Functions from the "Help" menu: User manual - Opens the user manual About - Shows a dialog box containing program specific information (e.g. program version). 3.1 Diagnostic Client Menu The submenu Diagnostic Client contains additional user interface layout options that are available only for a Diagnostic Client. Mainly, these options should improve the ergonomics on systems with more than one screen connected. Fig. 5: Diagnostic Client Menu Study Manager on first monitor If this options is checked and the application main frame is stretched over two screens on a dual monitor system, the study manager will be shown in a split pane in the first (left) monitor. Study Manager in separate windows If checked, the study manager will be moved into a separate window. This windows can be freely positioned on any screen. This option is recommended when using a system with two high resolution (medical) displays in combination with a 3 rd (smaller) display to be represent the study manager window. The keyboard shortcut CTRL-Shift-X can toggle this option on/off. The window JiveX [rv] User Manual

11 position is stored separately for both the detached study manager window view and the integrated view. Reduced Study Manager font size This option is only activated when the study manager is detached into a separate window. For ergonomic reasons, JiveX automatically adapts (increases) the UI font size when detecting displays of 2 megapixel resolution or higher to keep fonts readable. Using a 3-display hardware setup as outlined in the previous section, with the study manager placed on a 3 rd (lowres) display, fonts may appear too large on it. Checking this menu option now decreases the font size of the study manager again. All matrix allowed Using a setup with two highres (medical) displays for images, it is very unlikely that the user wants to see a single image stack stretched over both monitors, cut by the monitor frames. Thus, the Diagnostic Client offers an option to disable such matrix settings (default is false, if not stored otherwise in the user profile). If required, the option can be enabled again. Normal Layout / Multi Monitor Layout This switch toggles the UI layout between standard layout and a layout adapted for a two display setup. If set to Multi Monitor Layout, the image viewer is optimized for systems with more than one (highres) display attached. For example, in Multi Monitor Layout, the preview and function panel will be cloned, one for each screen. 3.2 Demonstration Client Menü The submenu Demonstration Client contains additional user interface layout options that are available only for a Demonstration Client. Mainly, these options should improve the ergonomics on systems with more than one screen connected. JiveX [rv] User Manual

12 Fig. 6: Demonstration Client Menu Split user interface If this option is checked, study manager and image viewer will be arranged side by side in one frame (intended to be stretched over two displays). Study Manager on first monitor If this options is checked and the application main frame is stretched over two screens on a dual monitor system, the study manager will be shown in a split pane in the first (left) monitor. Study Manager in separate windows If checked, the study manager will be moved into a separate window. This windows can be freely positioned on any screen. This option is recommended when using a system with two high resolution (medical) displays in combination with a 3 rd (smaller) display to be represent the study manager window.

13 Study Manager Image Viewer This options are available only when using the Split user interface. Here, you can toggle the layout (positioning) of the Study Manager and Image Viewer in the application frame, either left right (default) or right left. Normal Layout / Multi Monitor Layout This switch toggles the UI layout between standard layout and a layout adapted for a two display setup. If set to Multi Monitor Layout, the image viewer is optimized for systems with more than one (highres) display attached. For example, in Multi Monitor Layout, the preview and function panel will be cloned, one for each screen. 3.3 Mammography Client Menu The submenu Mammography Client contains additional user interface layout options that are available only for a Mammography Client. The options available are identical to the options for the Diagnostic Client, see section above. Fig. 7: Mammography Client Menu 4 Tool bar Right below the menu bar the tool bar offers quick access to some of the most commonly used actions. The appearance/display may vary because some action are not available to all users due to restrictions specified in the user profile. The tool bar can be switched off using the "view" menu.

Its mainframe is divided into a database service provider, a search area, a series display and a status bar. The database service provider contains general functions, e.g. program information and log out. In the search area, criteria can be defined and a search can be run. The series display shows the search results and provides functionalities for the image communication. When logging out, the position and size of the application s main frame is stored on the JiveX Server. 5.1 Search area The search area (Fig. 9) is an application for series searches in a chosen database. By clicking on the triangle in the upper left corner, the display of the search area box can be minimized. JiveX [rv] User Manual

In case you use the JiveX [rv] Client to access data from a non Visus-JiveX component, it might be necessary to change the *-symbol to the %-sign Search configuration You can modify some of the search parameters using the Search configuration - dialog box from the Extra -menu. There you can specify how many studies and series are shown at once in the study manager s tables. You can also configure an update interval. If this function is enabled the last search is rerun after the specified amount of time. JiveX [rv] User Manual

16 5.2 Series display The series display (Fig. 10) lists the search results in a table and provides functionality for image communication. Fig. 10: Series display The table displays identified entries in the following way: Archive status - The archive status indicates if a study has been archived. The study has not been archived yet. The archiving process for the study has been started. The study has been archived. Online status - The online status indicates a series'/study's image availability Uncompressed image data is available. Only compressed image data is available. There is no image data (available) online. To access the specified series/study a Restore Job has to be created. The following functions can be applied to the entries: Request a series. Request a series and loads it in the second viewer. Request key images only on/off. Request compressed images on/off. JiveX [rv] User Manual

17 Show all studies for the selected patient. Send the selected entry to a predefined DICOM node. When connected to a remote server and a local worklist is available this action transfers the selected study to the local worklist. Display all study relevant information in a separate dialog box. Add the currently selected study/series to the image report selection. Open the image report dialog box for creating image report jobs. Restore archived image data from an offline archive. Change a series assignment. Delete all selected studies from the database. Note: The buttons' availability depends on the currently logged in user's profile. For example, the Delete-button is only available in administrative accounts / if you have administrator rights Result set The resultset for a database query is limited to a certain number of rows. Please use the following navigation buttons to browse through the result set: First series or study. Previous series or study. Next series or study. Last series or study Sorting By left-clicking on the column s header, the column is sorted in ascending order. A second mouse click sorts it in descending order. An arrow inside the table header indicates the sorting order. JiveX [rv] User Manual

18 Fig. 11: Arrow indicating the sorting order It is also possible to define a second and third sort criterion in the user's profile Optimal width for columns Please Double-click on the head of a column to set it's optimal width. Please use the context menu of the column head to calculate the optimal with for the whole table Configuring the table It is possible to configure the table s columns.

This opens a context menu (Fig. 12) which enables you to either disable the selected column or to enable any of the columns listed in the menu. Fig. 12: Configuring the Series display You can also resize the tables' height by dragging the horizontal bar between the two tables up or down. Another possibility is to maximize each of them pushing the little arrows on the left side of the divider bar. JiveX [rv] User Manual

19 Fig. 13: Arrows Result view If configured by the administrator the Review Client is able to integrate a text area in the lower table in which result texts are displayed when available. Fig. 14: Result text area You can manipulate the text area size in the same way as the table size. 5.3 Actions To request a series of images, they need to be selected from the table first. The corresponding series is displayed after either pressing <enter> or clicking on the button or. Additionally, it is possible to request a series of images by double-clicking on their respective table entry. JiveX [rv] User Manual

20 To request two series simultaneously e.g. for comparative reasons (or a direct comparison), you have to select them both and confirm by pressing <enter> Requesting key images Using the toggle button, it is possible to suppress loading non-key images when requesting a series or study. If the requested series does not have any key images this option will be ignored and all images will be shown Requesting compressed images Enabling the toggle button causes the Review Client to request compressed images from the server if available. Disabling it requests uncompressed images. If the requested series does not have or only has compressed images, this option may cause the client not to load any images Patient name filter To search for all available studies with the selected patient's name, please press the button Sending studies To send a study to a remote DICOM Storage SCP, select the study and push the button. Receivers that should be listed as targets have to be configured on the server by the administrator. JiveX [rv] User Manual

21 Fig. 15: Send study dialog box Select the target from the combo box in the upper right corner. Depending on the receiver's configuration a compression of image data may be available. After pressing the OK button a DICOM-Send-Job will be created. If no receivers are available a warning message will appear. Fig. 16: No receiver message Image Report The buttons and are explained in the chapter Image Report creation Restoring archived image data After image data has been archived it may be compressed or deleted. If you need the uncompressed image data (e.g. to generate an image report) you have to create a Restore Job. Select all studies you want to restore and press the button. If the selected studies do already have the status the request will be canceled and the following message appears: JiveX [rv] User Manual

22 Fig. 17: No restore job created - message Change Assignment It is possible to change a series assignment to a study. For example this way you can move a series from one study to another. Clicking the -button shows all functions in a separate window. Please note that the user needs DELETE-rights to use this function. Fig. 18: Assignment dialog box Depending on your selection in the series manager there are different functions available: Cut the currently selected series. Undo a previously cut. Paste a previously cut series to the currently selected study. Extract the selected series to a new study. You can edit some of the new study s attributes in a separate dialog. JiveX [rv] User Manual

23 Merge all selected studies. After selecting this function you have to select a master study into which all other studies will be merged Study Verification When using a DICOM Modality Worklist in your workflow, incoming studies can be automatically checked against existing worklist entries. Studies that can not be assigned to specific worklist entry, e.g. due to no worklist entry available during image acquisition or mistyped patient s demographic data at the imager s console, can retroactively be assigned by the user. To manually assign a study to a worklist entry, the acting user needs edit- and delete-rights in JiveX. The current status of assignment of a DICOM study can be reviewed in the according study table column: The study has not been assigned yet. An automated assignment of the study failed. This study has to be assigned manually by the user. A worklist entry has successfully been assigned to the study. An assignment of this study is impossible. To assign a study to a worklist entry or release the assignment again or to simply view the current assignment, please click the button to open the study verification dialog window. JiveX [rv] User Manual

24 Fig. 19: Study Verification Dialog The study verification dialog is divided into three functional parts: The uppermost panel that shows information about the currently selected study, the (collapsible) worklist query panel below and the worklist entry table in the lower part of the dialog. If, on opening the study verification dialog, the selected study has been assigned successfully, the worklist table will show the assigned worklist entry only. Otherwise, the table will automatically list the worklist entries of the past 7 days Navigation through Studies To select another study from the study manager table, you can use the navigation buttons in the upper right hand corner of the dialog, see Fig. 19. Alternatively, you can directly select a study in the study manager table with a single click; this will update the study verification dialog fields automatically Release an Assignment To release an already assigned study again, please click on the button Release. A release also will automatically reset the AccessionNr of a study. Please note that processing a release action might take some time, dependent on the study size and actual server workload, since every image of the study as to be accessed. After a release, the newly released study can be reassigned again. JiveX [rv] User Manual

25 Assigning a Study To assign a study, please select the related entry from the worklist table and click on the button Assign in the bottom left hand corner. A double click on a row in the worklist table will also trigger an assignment action. If an assignment of the study is not possible, the status display next to the Assign button will show an explanation why. Possible reasons are: The study is protected You don t have the necessary right to modify study assignments The study is currently processed by the server (e.g. during image data receive) The study is no longer available on the server No study has been selected No worklist entry has been selected In the case of trying to a assign a study to worklist entry is already assigned to another study, a warning dialog is displayed, see next figure. Thus, to assign the worklist entry multiple times, you must answer yes in this dialog. WARNING: Assigning a worklist entry to multiple study may result in data inconsistency! Fig. 20: Warning Dialog: Worklist entry already assigned Please note that processing a release action might take some time, dependent on the study size and actual server workload. Every image of the study is being accessed, changing the patient s demographic data, accession number and study description according to the selected worklist entry. After all changes have been applied, the next study from the study manager talbe will automatically be selected Deleting images A selected series can be deleted by pressing <delete> or clicking the button. However, use this command with care! Not only will the corresponding image files be deleted but also the corresponding database entry of the study.!!! Caution!!!

It consists of a pictorial index, a status bar. (Fig. 21) and additionally, there are viewports which display either a single image or a matrix of images (see section Altering the image matrix). The pictorial index contains all loaded images as thumbnails. The status bar provides information on the current display. When Compare Mode is activated, JiveX simultaneously displays two or more viewing sections. Thus you can easily compare images. JiveX [rv] User Manual

28 Pictorial index Status bar Fig. 21: Viewing section In Compare Mode the active viewport is marked with a green frame. You can select a viewport by simply clicking on it. If a viewport displays a matrix of images, the selected image has a cyan frame. There can only be one selected viewport or matrix element at a time. 6.1 The Pictorial Index The pictorial index displays a miniaturized overview of every image loaded in the viewing section (Fig. 22). These miniaturized images are ordered by image number derived from their DICOM information. If such a miniaturized image is clicked with the left mouse button, it is displayed in a previously selected viewport. This viewport is then marked with a green frame. If the thumbnail is clicked with the right mouse button, its successional images are displayed as well, provided the viewport shows a matrix. Otherwise, only the clicked image is displayed (see section Changing the Image Matrix). JiveX [rv] User Manual

29 Fig. 22: Pictorial Index When the mouse pointer is moved over a certain image of a viewport, the corresponding image in the pictorial index is marked with a white frame (Fig. 22). You can also drag and drop images from the pictorial index to the image viewport with a pressed mouse button. If you click the right mouse button on the pictorial index, a context menu allows you to toggle the current series sort order (of the series under the mouse cursor) or to remove the series or whole study from the viewer. 6.2 The Viewport The viewport is the display area for images. When the mouse pointer is moved over the image, the corresponding thumbnail in the pictorial index is marked with a gray frame. JiveX [rv] User Manual

30 The upper red box in the upper right corner allows locking an image (see section Locking Image). Locked images cannot be manipulated and are excluded from all following operations. This is of particular interest if you want to use the application mode Series. In this case image manipulations are applied to all images displayed in the viewing section, except the locked ones (see section Application Mode). For the JiveX[rv] and JiveX[dv]-Light the second red box allows to mark images as key images. The lower red box can be used to chain series. If you chain two or more series, you can pan, zoom, flip or rotate and navigate all these chained series simultaneously. However, the function Windowing is excluded from this chain mode. Patient information can be displayed in the viewport s upper left corner (see section Navigation Panel). In the middle of the right border you can display a ruler and at each side orientation letters can be shown. Additionally, the consecutive image number of each image in its series can be displayed. Clicking the right mouse button on the viewport opens a context menu (as long as the click position is not located on the border of an annotation). This menu (see Fig. 23) allows the following operations: Show one of the loaded series in the current viewing section. If you have more then one study, the series are submenu items of their studies in the menu. The action for the left mouse button can be toggled (pan, window, zoom or navigate). Viewer specific annotations such as patient information, a ruler, orientation letters, JiveX image number and user defined DICOM tags can be switched on or off. A copied annotation can be pasted to the current image or to all images of the current series. Change the scout icon or show cutlines or a locator image. Export the current image / matrix / series as JPEG, BMP, PNG, TIFF, etc. To print the current image / matrix / series use the print submenu of the context menu. The bottommost menu item will switch the compare mode on or off depending on the current mode. Selection of the series matrix (Compare mode=2x1, Single series mode=1x1, predefined matrices). Zoom to original size or to maximize the images in their viewports. Split series (only CT and MR see below). Toggle the series sort order. Choose a predefined window setting. JiveX [rv] User Manual

31 Fig. 23: Context menu Depending on the context, some more menu items are available: Lock all / Unlock all to lock or unlock all image areas of the selected viewing section. Show only key images / Show all images shows only the key images of the selected series or displays the whole series. Show previous study (inside) and Show previous study (aside): If you have a main examination (study) and one or some previuos studies, you can show the matching series of a previous study either series beside series or JiveX [rv] User Manual

32 the previous study beside the main study. Example: A main study (MS) of MR modality is shown in a 2x2 series matrix: T1 sag T1 cor T2 sag T1 cor A previous study (PS) now can be showed that way, that either relating series of the main and the previous study are showed side by side ( inside ) or that the studies are showed side by side ( aside ). The result would be: Show previous study (inside) T1 sag (MS) T1 sag (PS) T2 sag (MS) T2 sag (PS) Show previous study (aside) T1 sag (MS) T2 sag (MS) T1 sag (PS) T2 sag (PS) T1 cor (MS) T1 cor (PS) T2 cor (MS) T2 cor (PS) T1 cor (MS) T2 cor (MS) T1 cor (PS) T2 cor (PS) Attached to the right side of the image (matrix), a vertical scrollbar is displayed. It can be used to navigate through the currently loaded series: a mouse click above or below the scrollbar nub or on the scrollbar s arrows will shift the images in the current matrix by one complete matrix up or down (e.g. when the current matrix is 3x3, the next 9 images will be displayed). If the [CTRL] key is pressed while clicking, images will be shifted by one row up or down; dragging the nub itself will shift image-wise. You can also navigate through the series with the cursor keys, or with up- and down mouse-movements with a pressed right mouse button. Moreover, the mouse wheel can be used to navigate through the images of a series. It functions in much the same way as the scrollbar: Each wheel turn (click) shifts images matrix-wise, pressing the [CTRL] key while using the wheel will scroll by one row. If the S -key is pressed during the navigation and the viewer is in the compare mode, both series will be scrolled through synchronously by the same number of images. If the E -key is pressed during the navigation and the viewer is in the compare mode, both series will be scrolled through synchronously by the same distance in millimeter. However, if the two series differ in thickness, images might be skipped. Additionally, panning or zooming in/out on an image can be achieved by using the appropriate buttons on the mouse wheel. If you press the left mouse button (and hold it down) and then click the right mouse button, the action for the left mouse button is changed to the next possible action (see the statusline action icon) that means: window -> navigate -> zoom -> pan -> window. If at least two series are being displayed (with the same image direction), you can equalize the image planes of these series to view similar images of the same (nearest) image position. To do so you have to choose a source series to which you want to equalize another series. Press the shift key (and hold it down) and press the right mouse button over the "source series (and hold it down too). Then move the mouse to the "destination series and release both the mouse button and the shift key. The context menu will open and a new menu item named "Equalize image plane appears. Choose that item and the "destination series will show images of the same (nearest) image position as the source series. JiveX [rv] User Manual

33 In some cases you wish to change the image order, that means an image from e.g. the third position must be moved to the 5 th position. To do that you can select the image, press the shift-key (and hold it) and move the image with the left mouse button to the destination position. The images should be shown in a matrix. You can use the [Pause]-key to show all images of the current series in an optimized matrix. 6.3 Split series With the menu item Split series coherent CT or MR series and their series components are separated. There are three types of split methods: Acquisition technique, Time sequences and Position sequences. Acquisition technique With this method the images are checked for attributes of their acquisition technique and separated by differences. These attributes are e.g. echo time, repetition time, image orientation or a contrast agent. Time sequences In cardio diagnostics you often find sequences of images on the same position as a time sequence (e.g. over one heart beat). For example: over 30 images over time per 6 different positions. These series can be split keeping images of the same position together. With respect to the above mentioned example this results into 6 series each with 30 images. Position sequences Some modalities create series with multiple image positions like 30 coronal images of the head, 30 coronal images of the chest and 30 coronal images of the abdomen. JiveX [rv] User Manual

34 Such a series would be split into 3 series containing 30 images each. This method also allows to split images with the same image position (to allow MPR). 6.4 The Status Bar The status bar shows information about the viewport s status or the operations in progress. E.g. while performing a grayscale windowing, the status bar displays the corresponding values of the window s center and width. Fig. 24: Status Bar 6.5 Scouts and scanlines It is possible to display a scout inside the image viewport, in case of an existing scout image. After displaying the scout image you can set this image as image scout. JiveX [rv] User Manual

35 Fig. 25: Context menu The scout is then displayed in the bottom right hand corner of each image viewport. The scanline of each image is marked in the scout with a yellow line. The scout view can be disabled by selecting the appropriate menu item form the context menu Scanline display accuracy To calculate and display the scanline accurately, the angle between the norm vectors of the scout image plane and the displayed image plane should be less than 10 degrees. Dependent on the set recording parameters, this criterion may not be fulfilled in some studies. As a result mathematically speaking it is not possible to calculate an accurate value to display an exact scanline. However, by allowing a user defined "deviation of the expected 10 degree minimum angle JiveX is able to generate a so called projection of the image plane. This is then being displayed onto the scout plane instead of a scanline. In this case, the scanline is displayed "dashed. Additionally, a yellow exclamation mark with an according tooltip is being displayed on the scout image. JiveX [rv] User Manual

36 Fig. 26: Scanline plane angle warning 6.6 View cutlines Via the context menu you can activate the cutlines. If many series are displayed in each image the cutline from the selected (focused) image including the image number will be shown (if possible): JiveX [rv] User Manual

The "Previous Studies dialog box can be opened via the context menu (right click on image) or by clicking the button of the menu toolbar. The screenshot (see below) shows the way in which the dialog box lists all previous studies of the patient, here sorted by study date in ascending order. JiveX [rv] User Manual

38 Fig. 28: Dialog window Previous Studies" To mark studies for loading tick the checkboxes in front of the studies. Should only single series of a study be loaded, one click on the arrow of a study entry will expand the series list for that study. Once all required studies / series have been selected press the "Load selection key to initiate the data transfer. To load all studies listed you can directly click "Load all. "Cancel closes the dialog box without loading any additional images. Studies that are already loaded will be displayed in italic letters with a prefix <already loaded> whereas studies that are offline or not accessible will be marked with a prefix <not available>. The upper part of the dialog shows an Information section with a summary about selected/loaded studies as well as an Options section. Both sections can be expanded or collapsed using the small triangle buttons in the frame top. The section Options can set the following attributes for access to previous studies: Study Selection: Same JiveX Patient ID If this option is active, the study list will contain (all studies of) patients that are JiveX [rv] User Manual

39 detected by the JiveX Server to be identical with the case actually displayed. Same Patient ID If this option is active, the study list will additionally contain (all studies of) patients that have the same Patient ID as case actually displayed. filtered This is related to the option Same Patient ID. Since, principally, there might be DICOM studies in the system stored under a wrong Patient ID (because the modality sent it that way), the study list of all patients with the same Patient ID might contain data from more than one patient. If filtered is checked, falsely detected data sets are removed from the study list computed with the option Same Patient ID. Same name & birth date If this option is active, the study list will additionally contain (all studies of) patients that have the same name and birth date as case actually displayed. Additional Study Information: Patient name If selected, the patient s name is displayed with each entry in the study list (see Fig. 28). This can be useful when patients with identical Patient ID are dislayed, to check whether all studies are from the same patient or not. Patient birth date If selected, the patient s birth date is displayed with each entry in the study list. Patient sex If selected, the patient s sex is displayed with each entry in the study list. Please remark that changes in the Options section will not be applied directly to the study list. You will have to click the buttn Update first. 6.8 Multi Monitor Support By default, multi monitor systems are supported. For a proper display, dual monitor systems must fulfill the following requirements: Both monitors running at identical screen resolution Both monitors running at identical color depth (using an identical color model) The multi monitor mode of the image viewer is optimized for two monitors in a row, one next to each other (nevertheless, two monitors in a column are possible as well). The user interface of the image viewer will automatically switch to special mode adapted to multi monitor display, as shown in Fig. 29. JiveX [rv] User Manual

40 Fig. 29: User interface in multi monitor mode One function panel together with a preview bar is displayed to the left and right hand side of the application frame. The functionality of both areas stays transparent, e.g. modifying the zoom factor on the left function will move the slider on the right functions panel as well. In dual mode, actions will always be applied to that series (or image) which is currently being selected (marked by the green frame). The other differences to the single monitor mode are: Dialogs and input boxes are placed on the screen relative to the position of the mouse pointer. For Example, if the mouse pointer is on the right monitor, the print preview dialog box will appear in the center or the right monitor. The layout of the image viewer is optimized for a full screen display. This guarantees that when the application s main frame is maximized to full screen, none of the images displayed in the matrix is cut by a monitor s frame. In contrast to single monitor systems, when running the image viewer in single mode, only those matrixes with an even number of columns are allowed. In compare mode, any matrixes are allowed. Pressing the CTRL key while the application s main window is maximized through a mouse click, the window will be stretched on both monitors and take up all the available space Connecting different Monitors The dual monitor mode with Windows operating systems by default does not forbid using different Monitors, e.g. with different resolution or color depth. If the monitors connected do not have the same screen resolution, the user interface of JiveX will not automatically switch to dual monitor layout. If the monitors do not use the same color depth, JiveX will always use the color model of the primary system monitor as a base for calculation and display of images. JiveX [rv] User Manual

41 6.9 The Viewing Section Toolbar The viewing section toolbar is organized in tabbed panels which provide various controlling and image manipulation functions (Fig. 30). Grayscale windowing is only one example of the functions contained in the Function tab panel. Opening the tab panel Cine offer the possibility to perform a filmlike display of all images of a viewing section ( Cine-loop ). The tab panel Annotations contains functions to create and manipulate graphical and textual annotations. The different functions are organized in function groups. Each group has its own frame with a small click-able triangle in the upper left corner. When clicked with the left mouse button, this triangle opens or closes a function group (Abb. 9/10). If the triangle points up, the function group is open showing all the avaliable functions. If the triangle points down, the function group is closed. Fig. 30: Viewing Section Toolbar JiveX [rv] User Manual

42 6.9.1 Processing Functions Application Mode The application mode defines if image manipulations, e.g. grayscale windowing or zoom, are applied to single images or to complete series. Fig. 31: "Apply to" Function Group The following application modes are avaliable: Image Manipulations are applied to the image previously selected. The selected image is marked with a green frame. Series Manipulations are applied to all images of a series except the locked ones. In Compare Mode, manipulations are applied only to the series of the currently selected viewing section. Please remember that geometric and textual Annotations (see chapter Image Annotations), Calculations (see chapter Calculation Functions) and Shutters (see chapter Shutters) will always be applied to the actual image. In this case, the selected application mode will be ignored Image Locking Locking an image: Each viewport has a small red box in the upper right corner (Fig. 32). This box can be activated and deactivated with a mouse-click. If an image has been locked, it will be excluded from all manipulations applied hereafter, until the lock is deactivated again. Alternatively, in order to lock or unlock images, you can also use the context menu. JiveX [rv] User Manual

43 Fig. 32: Activated lock Selecting an Image An image is selected by clicking into the viewport displaying the image. The viewport is then marked with a green frame. The corresponding image in the pictorial index is also marked with a grey frame (Fig. 33). JiveX [rv] User Manual

46 Fig. 36: Context menu with window presets Zoom Functions Another function group within the viewing section toolbar provides further options to alter the size of the images. An absolute magnification can be entered into the input box. Images can be dynamically zoomed out or in by using the slider. The icon 1:1 displays the image in its original size (or exactly: One pixel of the DICOM image corresponds to one pixel on the monitor). JiveX can auto-calculate the image size in order to optimize its fit in the viewport. To do so click on the icon Fit to Viewport. Fig. 37: "Zoom" Function Group Clicking on the icon ROI Zoom (Region Of Interest) (Fig. 32) selects a desired area of the image using the mouse. First, activate the icon ROI Zoom with a mouse click. Then, position the mouse pointer on the image and select/mark the desired area (keep the left mouse button pressed while moving the mouse). A yellow rectangle appears which marks the selected area. As soon as you release the mouse button, the selected image area is adapted to the current viewport size and displayed zoomed in maximally. To change the zoom factor press the Z -key whilst dragging the image into the viewport with the mouse. JiveX [rv] User Manual

47 With the Adjust Ruler -checkbox you can adjust the rulers of all visible images, so that all images have the same measurements. If one of the images is then zoomed in/out, all images are adjusted in their size accordingly. Please note that images without given pixel sizes are excluded from this ruler adjustment Filter If images are displayed inside the viewer you can decide which kind of display method should be used for the images. At the moment three different types are supported. These filter types are applied to all images inside the viewer: Unfiltered. If images are displayed with a zoom factor greater 1.0 the additional pixels are replicated. Interpolation. If images are displayed with a zoom factor greater 1.0 the additional pixels are calculated as average values to generate a smoother look. Sharpen. Edges within images are emphasized (big color changes are called edges). Fig. 38: "Zoom" Function Group Magnifying Glass The magnifying glass option allows to magnify sections of the underlying DICOM image without loosing the orientation inside the image. The magnifying glass can be moved over the image using the mouse. To move the selected area or to resize it just drag the mouse inside the resizebox in the bottom right hand corner of the magnifying glass area. JiveX [rv] User Manual

53 6.9.3 Image Annotations There is a whole variety of drawing tools to annotate images. They have their own tab panel in the viewing section toolbar of the viewer. Fig. 43: Overview Annotations JiveX [rv] User Manual

54 Drawing Annotations Please, select a color and a type for the annotation you wish to create (see Fig. 44). All annotations except polygons require two clicks with the left mouse button. Click once to start drawing the annotation, then move the mouse pointer and click a second time to finish the annotation. When drawing polygons, use as many left mouse clicks as you need to define new polygon points. A final double click will finish the annotation. Circle Rectangle Closed polygon Arrow Circle with center point Text with anchor point Circle over 3 points Ellipse Text annotation Fill annotation Line Open polygon Fig. 44: Types of Annotation A dialog box is opened when creating a textual annotation. Please enter your annotation text into the text field of this dialog box. Further characteristics can be defined here: the positioning of the text, its color and the creation of an anchor point if desired. After confirming the entry, the position of the text is determined by the first mouse click, the anchor point is set with a second click. If you press the [C]-key while creating an annotation, the mouse cursor will be hidden to allow accurate positioning of points/lines/objects. JiveX [rv] User Manual

55 Textual annotations with anchor point Textual annotations without anchor point Fig. 45: Textual Annotations Manipulating Annotations Existing annotations can be altered. By simply clicking on an annotation and keeping the left mouse button pressed, it can be shifted. Please make sure you click on the (imaginary) bounding box of an annotation you wish to modify. If an annotation has been selected, a context menu can be opened with the right mouse button. From this context menu a property dialog can be opened. The position of the annotation can be altered in relation to other annotations and it is also possible to delete the annotation completely. In the property dialog of a graphical annotation, it is possible to subsequently alter the color of the annotation. Unfilled closed annotations can be filled and vice versa. Annotation positions can also be converted from image relative into display relative, which means, that they are not shifted together with the image anymore. If you are creating textual annotations, a dialog box - similar to the initial property dialog - appears. Here, the text can be corrected, its position can be altered and the anchor point can be switched off. Additionally, the color can be changed and switched from image relative to display relative. Normally you can either move the text of a textual annotation or its anchorpoint. If you press the Ctrl-key during the move you can move the whole textual annotation. You might be in need of the option to alter the order of overlapping or filled in annotations on the screen. In that case, you are able to use the context menu to shift annotations from the background to the foreground Deleting Annotations An annotation can be deleted by using its context menu.

56 Calculation Functions On the images, distances and angles can be displayed and a statistical evaluation of the pixels can be run. Annotations are drawn in the pre-selected color and are created as explained above. To calculate an angle, the three points of its two arms are entered through mouse clicks. Distances are calculated the same way as lines are drawn and running a statistical evaluation is comparable to the drawing of a rectangle. The image DICOM information is used for the calculation. If no size information is contained in the image, the distance information is specified in pixel values. Angle measurement Open angle measurement 3 way angle measurement 4 point angle measurement Distance measurement Line relation measurement Parallel line with distance Plumb line with distance Statistic measurements (rectangle) Statistic measurements (polygon) Statistic measurements (circle) By using the context menu, it is possible to subsequently alter the color (by clicking on properties ) as well as the position. It is, of course, possible to delete calculations again. For the both open angle calculations you can move the lines or the text separately from the whole annotation if you press the Ctrl-key during the move Shutters By using shutters, structures inside a chosen area can be shut out. There are three different types of shutters (circles, rectangles and polygons). Each one of the three can be used only once on an image, in accordance with the DICOM standard. It is, however, possible to combine the different types of shutters. With a second click on a shutter button you can remove a selected shutter type. A selection list among the buttons enables you to define the gray value used to fill the shutter s surrounding. JiveX [rv] User Manual

58 6.11 Volume Rendering The Volume Rendering function panel (Fig. 46) offers different methods for planar reconstructions (axle-parallel ( axially ) and inclined ( oblique )) of a series. The reconstructed image stack is created dynamically and initially exists in the memory of the computer only. Before a reconstruction is possible, any series to be reconstructed must be loaded completely into the JiveX viewer. The reconstruction is produced on demand on click of a button (section ). Fig. 46: The Volume Rendering function panel The section describes how to create a MPR whereas section describes the different properties of the reconstruction. The MPR function is only selectable if the series loaded permits an appropriate treatment. Otherwise the control elements are deactivated. JiveX [rv] User Manual

59 Creating a planar reconstruction The function group Create MPR offers functions to assist planar and inclined reconstruction. These functions are available only if the series is loaded completely into the viewer and is suitable for a multi-planar reconstruction (see section ). A planar reconstruction is accomplished with the orientation buttons (see Fig. 47). The reconstruction takes place alternatively axially or oblique: Fig. 47: The function area for the creation of a dynamic picture series: Line 1: individual axial reconstructions (coronal, sagittal, transverse) and all three axial directions; Line 2: oblique reconstruction and all four directions Every of the four possible axle-parallel space orientations coronal, sagittal, transverse and oblique is represented by a button. The dynamically reconstructed image stack replaces the current view in the viewport. When first shown, the middle slice of the reconstructed stack is initially selected in the viewport. All three reconstructions (coronal, sagittal, transverse) are computed in one step by the button. The display changes to a 2x2 series matrix with a1x1 picture matrix (stack) each. All currently displayed series are replaced by the newly produced reconstructions. This button serves as a shortcut to generate all three axial reconstructions. All four reconstructions are computed in one step by the button. The display changes to a 2x2 series matrix with a1x1 picture matrix each. All currently displayed series are replaced by the reconstructed stacks. This button serves as a shortcut to generate all four reconstructions. All processing functions available for static image series are available for reconstructions, too (cutlines, windowing, zooming, etc.). The reconstructions are represented as newly generated image series in the pictorial index with a series description defining the axle of the image stack. In contrast to static picture series the dynamic reconstructions are not represented through thumbnail views of the original sized images and their view can not the deflated ( reduced view ). In the top right hand corner of the images displays an overlay text to indicate that the stack is a reconstruction. If a Slab is selected (see section ), the slab thickness is appended to the text (see Fig. 48, Fig. 50). From the original series, a reconstruction can be created only once per axle and per display method, resulting in a maximum of 12 possible dynamic reconstructions (three display methods for any of the four image space orientations). If the execution of an already existing reconstruction is requested, JiveX [rv] User Manual

60 the reconstructed series is loaded into the active viewport and no new reconstruction is created. Fig. 48 shows reconstructions of all four image space orientations. Fig. 48: Reconstructions of all image space orientations Manipulating a reconstruction After a reconstruction has been done, its representation can further be changed using the properties area. The control elements are selectable only if a dynamically produced reconstruction is in the current (active) viewport. Elements which are not applicable for the selected picture series are deactivated. On static picture series, none of the operations is possible. Some control elements are selectable for all reconstructions, others only for oblique reconstructions. Section describes the elements which are selectable for all reconstructions. Section describes the elements which are only applicable for the oblique reconstruction only. In section , further characteristics of the oblique reconstruction are described. Requantization as a special manipulation of a selected (source) series is described in section JiveX [rv] User Manual

61 Properties for all reconstructions Two parameters are available for all reconstructions: the Slab and the Display Method The Slab A manipulation of the displayed volume range can be done by defining a Slab. A range of a volume is called Slab if it represents a range (number of) of subsequent images of the image stack that is rendered to the screen using a defined algorithm (e.g. MIP) and displayed as one slice. The Slab can be defined by a number of images to be combined or in mm thickness There are two input fields available for changing the Slab. The view of a slab displayed in a viewport is updated automatically after any input change in either of the fields. Remark that the two input fields are linked, that means that altering the value of the one will automatically adapt the other. Fig. 49: Defining the properties of a Slab The default Slab for any created reconstruction is set to 1 slice that is equally to the slice thickness as defined in the recording parameters of the imaging modality 2. The Slab is calculated immediately by the help of the voxel spacing of the images series. The correlated input field of other unit is updated immediately. The Slab can be defined slice-wise on the original image stack only. If the Slab is defined by distance in millimeters, it is rounded automatically to a multiple of the slice thickness. Example: The transversal images of a series have a slice thickness of 2mm. Thus, the spacing in view direction summarizes in 2mm steps. This means, a Slab of 10 layers measures 20mm. Although a Slab of 19,9mm can be entered in the input field Distance [mm], this value is rounded on 20mm, since only whole voxel layers can be summarized. If a Slab of 5 layers is entered, a corresponding distance of 10mm is computed automatically. Fig. 50 shows JiveX after a change of the Slab. 2 For axially parallel reconstructions, the spacing of the z-axle is defined by the pixel spacing of the original series. Doing oblique reconstruction, the smallest spacing occurring in the volume is used. JiveX [rv] User Manual

62 Fig. 50: The viewer after modifying of the Slab. In the top left viewport shows the coronal reconstruction with a Slab of 24 layers. The Slab is indicted by the green lines in the other reconstructions. The annotations in the top right hand corner of the viewport show the selected Slab and the used display method (MIP, AVG or MIN). The Slab can be individually adjusted for each reconstruction and will be indicated in the other viewports if cutlines are activated The display method For the summary of several image stack layers through a Slab, three different display methods are available (see Abb. 6). These are: MIP Using the Maximum Intensity Projection, each displayed pixel represents the largest, i.e. the brightest gray value that occurs at this position in the layers which are to be combined by the adjusted Slab into one image. AVG Using Average Intensity Projection summarizes all pixel values at a position in the layers and calculates the arithmetic average, which is displayed. MIN The Minimum Intensity Projection is the counterpart to the MIP algorithm, using the smallest occurring gray value. JiveX [rv] User Manual

63 Fig. 51: Selection of the display method. Any newly created reconstruction is initially using the same display as its origin, or MIP if the original series was a static series. The display method can be changed at any time. However, changing the display method will create It is to be noted however, that the represented dynamic series is not changed, but that a new series with the selected display method is produced. An example showing all three display methods is shown in Abb. 7. JiveX [rv] User Manual

64 Fig. 52: Different display methods compared: All reconstructions show a Slab of 25mm as visualized in the cutline of the bottom right hand corner viewport. The top left shows a Maximum Intensity Projection, the top right an Average Intensity Projection and the bottom left a Minimum Intensity Projection Modifying the oblique reconstruction For the oblique reconstruction, besides the properties already introduced, supports additional properties for manipulating the view axle (Fig. 53). JiveX [rv] User Manual

65 Fig. 53: The parameters of the view axle. The right slider represents the rotation of the horizontal axle, the lower slider the angle of the vertical axle. The values for the angles are whole degrees measured in goniometer unit ( ). The view axle equals to the direction in space of the z-axle of the viewport showing the oblique reconstruction. The view axle can be modified by two sliders representing the rotation angles: One for setting the horizontal axle of the view (the rows of the images), the other for the vertical axle (the columns of the images). The rotation axle settings remain constant even when a series is rotated or flipped. The button resets both angles to zero, shifting the oblique reconstruction into its initial position. The rotation angles can also be interactively manipulated with the mouse: press the X key on the keyboard and the left mouse button together. The mouse cursor should change to a oblique rotation arrow cursor. Moving the mouse up and down changes the horizontal angle, left and right changes the vertical Algorithm used for oblique reconstruction The computation of the oblique reconstruction is far more complex than a standard computation of the stack along the default transversal, sagittal or coronal axle and requires high CPU usage. Depending in the number of images in the stack and the slab range, there may be noticeable delays in the screen refresh when interactively changing the view axles. If the delay is not acceptable and should be avoided, it is possible to modify the computation of the reconstruction. The algorithm will then compute less voxels, resulting in a faster screen and refresh less exact view during rotation. Fig. 54 shows the control elements for adjusting the interactivity. JiveX [rv] User Manual

66 Fig. 54: Selecting the quality of reconstruction There are three settings available: The setting Accurately is activated per default. Each pixel of the displayed picture is visualized at a maximum quality. The algorithm takes more computational steps and may result in a slower refresh. The setting Speedily is a compromise between view accuracy and speed 3. If the setting Fast is selected, it is guaranteed that at least 5 pictures per second are reconstructed. Depending on speed of your computer, the image quality may be reduced noticeably. A reduction of the image quality as a result of the setting Speedily or Fast is applied only while changing the view axle interactively. Once the mouse button is released, the view is recomputed at maximum quality! Requantize an image series A reconstructed image stack can, when displayed, be requantized by clicking the Requantization button on the function panel (see Fig. 46). The process of requantization (irreversibly) summarizes a defined number of slices of its original image series. Thus, a requantization offers the possibility to reduce the overall number of images of a series, e.g. for export or printing purposes or for reducing the amount of data. The requantization algorithm is basically identical to the slab calculation on a dynamic series as introduced above. The user specifies the number of summarized image slices (see section ) and a display method (see section ). Both input field are pre-filled with the values of the series to be requantized (that is in the currently selected viewport). Fig. 55 shows the requantization dialog window. 3 This setting replaces the Trilinear interpolation with a Nearest Neighbour interpolation. JiveX [rv] User Manual

67 Fig. 55: The Requantization dialog window: The box current series shows the properties of the selected original series. The input fields in the lower part of the dialog preview the properties of the requantized series. The input field Number of summarized slices is currently the only modifiable value. The value entered defines number of slices in the resulting series and their slice thickness accordingly. Confirming with OK starts the requantization process immediately. The new image series is added automatically to the viewer. The original series is not removed and is still available. A requantized image series is no longer a dynamic series. Its properties, e.g. the number of requantized imges and the viewing method can not be altered after the requantization process. In most cases, the number of slices of the image series to be requantized may not be divided by the number of slices of the resulting series without a numerical rest. Thus, the last slice of the resulting series usually is a bit thinner. Because of the last thinner slice, a requantized series may not be suitable for a planar reconstruction any longer (see section , statement 5) Preconditions for reconstruction The planar reconstruction cannot be applied to all image series. The following preconditions must be fulfilled: 1. The series must contain at least two images. 2. The pixels of the source image series must be stored with 16 Bits gray or less per pixel (DICOM Tag Bits Stored (0028,0101) ). 3. The pictures are sorted ascending by image position. It is recommended to use the Hanging Protocol feature Automated Image Sorting to ensure the correct order. If this Hanging Protocol option is deactivated, the resulting reconstruction might appear headfirst or can not be created at all (buttons stay disabled). 4. All images of the source series (stack) are parallel in their z-axle. 5. The distances between each pair of images is constant throughout the whole series and is not equal to zero. JiveX [rv] User Manual

68 If one or more preconditions are not fulfilled, a reconstruction is not applicable and the control elements of the Volume Rendering function panel (see Fig. 46) stay disabled. JiveX [rv] User Manual

69 6.12 Exporting to JPEG, BMP, PNG, PNM, TIFF, AVI and DICOM JiveX supports the export of images in JPEG, BMP, PNG, TIFF, PNM and DICOM image format. Please click on the Export -button on the navigation panel (see chapter Navigation Panel), to select images and save them to the hard drive (disk). There are a number of selections to choose from before saving the image: The user can either export the original image with its present windowing status or alternatively export the image together with the currently selected viewport and all the annotations belonging to it. (Not available when exporting to DICOM) Either the selected image, the current matrix or all images of one series can be exported. The size of the image to be exported can be changed. (Not available when exporting to DICOM) When exporting to JPEG you can choose between three different levels of quality. The higher the quality, the larger the exported files. When exporting to DICOM you can anonymize the DICOM files. Fig. 56: Export If exporting a matrix or series, the image number will automatically be appended to the filename. If e.g. a series of 42 images is exported to JPEGs using the filename TestSeries, files named from TestSeries_000.jpg to TestSeries_041.jpg will be generated. While the export runs, a progress bar is displayed to inform about the export status. JiveX [rv] User Manual

70 Properties of AVI Export Limitations The export to AVI file format is available for DICOM multiframe images only and must be separately configured in the user profile. By default, the export to AVI is disabled. Codec For exporting, the AVI data stream is generated by the JiveX Server. Thus, the compression algorithm ( codec ) used is also configured in the JiveX Server. The default codec used is the XVID codec which generated MPEG4 compressed data. To playback the AVI file, you must have an MPEG4 codec installed on your computer. Duration Creating an AVI from larger DICOM multiframe series is a CPU intensive job and might take some time, dependent of the current workload of the JiveX Server. When creating an AVI, the following dialog is displayed. If you choose to Continue working, the JiveX Review might react somewhat slower for the time the AVI is streamed. Fig. 57: Continue work during export 6.13 Key Images Key images can be defined to mark result-relevant images. To mark an image as a key image click in the second red box located in the upper right hand corner of each image viewport. A key icon is being shown in this box. To remove the key image status, just click in this box again. JiveX [rv] User Manual

71 Fig. 58: Key Images In the thumbnail tree key images are marked with a key symbol, too. The context menu of the image viewports opens the result view. From this dialog box you can save the key image status (among other things). Out of the study browser you can load only those images (out of a whole series) which are marked as key images. To do so, please click on the button with the key symbol. JiveX [rv] User Manual

The hanging protocols allow you to introduce those settings. With the Extra-menu you can open the hanging protocols-editor dialog window (see below). JiveX [rv] User Manual

91 Fig. 67: Hanging Protocol editor Hanging protocols can be applied to studies and their series that fit a given criteria, consisting of a modality and a study description. They also have an alias name for an easier identification. This alias name will be shown in the context menu for subsequent use too. An important attribute is also the function use automatically. If the box is ticked, a hanging protocol can be used automatically while loading images. Otherwise you can use hanging protocols subsequently over the context menu. To create a hanging protocol for all studies/series, just enter an asterisk in the modality and study description field. This asterisk can be used as a wildcard. To define additional conditions, click on the 3-points-button on the right side of the condition-dropdown-list. A new dialog window will open (see next figure): JiveX [rv] User Manual

92 Fig. 68: Condition editor Here you can enter a list of DICOM-tags with an alias name (which can be selected in that drop down box in the hanging protocol dialog). You can choose an operator (=, >, <, >=, <=,!=) and a value to check. All topics of a hanging protocol can be accessed via tabs ( General, Full screen, Matrix, Series and if applicable Mammography and Previous Studies ). If the viewer contains DICOM images, the study and series description fields on the respective tabs can be filled automatically with the known descriptions. In this case right of these fields a button will appear. After clicking on this button, a drop-down list will open with all study or series descriptions (depending on the field) known in the viewer. Any change to the hanging protocols must be accepted with the Update -button, a selection of another hanging protocol accepts changes, too. The Copy -button duplicates the current hanging protocol (which is not used automatically because the criteria will overlap with the source hanging protocol). The dialog box can be closed with the OK -button (all changes will be saved) or the Cancel -button (without saving the changes). Please note: Any changes to the hanging protocols will be save to your user profile (on the server) when you log out of JiveX[rv]. However, just closing the JiveX[rv] application will discard any changes! 9.1 The General -tab The General -tab contains attributes for common viewer settings. JiveX [rv] User Manual

93 Fig. 69: The General -tab Use automatically means this hanging protocol can be used during the image loading process. Otherwise it can be applied subsequently. If there are many hanging protocols with the same criteria (modality and study description) only one hanging protocol can be used automatically. This attribute is equal to the checkbox inside the table with the list of hanging protocols (first column, named Use ). Summarize all images means that series from the same modality will be summarized to one series of that modality. Split multiframes will separate all frames of a multiframe image Automatic sorting will sort all series in the same direction which means from anterior to posterior, from right to left and from head to foot. A given series sorting in the series tab will override this setting. Automatic image orientation will rotate or flip images to achieve a standarized image orientation Restricted sync. Scrolling will scroll linked series only in case of an equal image orientation. Filter HPs in contect menu will hide HPs with a wrong modality or a wrong study description Cutlines: Enables or disables cutlines inside the viewer. Ruler adjustment: Enables or disables the ruler adjustment mode. Autoplay multiframes will start the cine mode after navigating to a multiframe image Apply functions to: Changes the mode to this image or current series. Image filter: Changes the filter method for image visualization. Possible values are: Interpolation, unfiltered and sharpen. Function panel: Shows or hides the function panel. Thumbnail tree: Shows or hides the thumbnail tree. Play AVI/MPG in fullscreen will play movies in a fullscreen player Don t show scout series loads but not visualizes scout series Next HP will define a following hanging protocol that can be applied with the [+]-key on the numeric key pad. The previous called HP cann be applied with the [-]-key on the numeric key pad. JiveX [rv] User Manual

94 9.2 The Fullscreen -tab The Fullscreen tab will configure the appearance of an image after double-clicking on it. Fig. 70: The Fullscreen -tab Fullscreen is equal to a 1x1 series matrix does not open a fullscreen window with the selected series, but changes the series matrix to 1x1 (per monitor) and shows the selected series there. The Fullscreen-Imagematrix defines the image matrix inside the fullscreen mode (after a double click on an image). The default matrix is 1x1 per monitor. In case of a double monitor system you can decide (if you maximize only one series) if this matrix is expanded to all monitors or if it defines the matrix on one monitor. Start cine in fullscreen starts the cine mode after maximizing an image Show functions in fullscreen shows a toolbar with the most common viewer functions on the top border. Always show one series in fullscreen maximizes always only one series, even if normally two series would be maximized on a double monitor system. 9.3 The Matrix -tab Inside the Matrix -tab you can define a series and an image matrix. You can also assign series to viewing sections and link them with other series. To assign series to viewing sections, enter the series description at the correct series list item and - in case of loaded preliminary enquiries include the study index (values from 1 to n). The main study has the index 1, previous studies start at index 2. If you wish to show a specific image inside a series, you can set the image number. To link check the checkbox Link. You can also create MPRs in three orientations (coronal, sagittal, transversal) with three methods (MIN, MAX, AVG). JiveX [rv] User Manual

95 Fig. 71: The Matrix -tab 9.4 The Series -tab Inside this tab you can change series-specific attributes like window settings, zoom or topogram settings: Fig. 72: The Series -tab For multiple series settings just add a new series item (see buttons "New and "Accept series ). With the series description the right settings for a series can be both found and applied. Existing series items will appear in the list box on the right side. JiveX [rv] User Manual

96 Separate combined series separates combined series to different series like functional heart scans (multiple image planes for different times). The following four window setting types cannot be selected at one time. Only one or none of these settings can be used: Window defines a window for a series. Use Pixel Range means, a window will be calculated out of the minimal and maximal pixel value of a series. Window-Offset defines an offset for a given window. The center and width values are added to the given window. Optimize Window calculates a window out of the pixel range, excluding a proportional percentage derived from the upper and lower pixel values. Ignore Presentation LUT ignores a PLUT that could incorrectly invert images. Invert series inverts a series Zoom defines a zoom factor for a series. Image sorting defines a sort order for images inside a series. If the automatic sorting is activated, this setting overrides the automatic sort order. Topogram shows a topogram icon on each image in the bottom right corner. In case of IHE-conform images the topogram icon can be found automatically or it can be manually specified by a series description and an image index (values from 1 to n). Image locator shows the image locator inside the image area. 9.5 The Mammography -tab The Mammography -tab is only available in the Mammo Client. This menu specifies the alignment and orientation of mammography images. JiveX [rv] User Manual

97 Fig. 73: The Mammography -tab Correct orientation of mammo images flips mammo images if necessary. Auto image alignment sets images to left or right alignment (in relation to the center) Ignore VOI LUT ignores a VOI LUT to avoid a false image visualization Auto shutter enables the mammography auto shutter Image order defines the image order for mammography images as RCC-LCC- RMLO-LMLO or RCC-RMLO-LCC-LMLO Start sector sampling starts the sector sampling Place earlier views to the end places wrong images with an earlier timestamp always to the end of the mammo series. 9.6 The Previous Study -tab With this tab you can load fitting preliminary enquiries. If the box Load previous Studies is checked, fitting studies will be loaded in addition to the chosen study from the JiveX[rv] series manager. These studies can be restricted with the following options: Maximum number of studies restricts the number of additional loaded studies. Starting from this date sets a start date from which studies can be loaded Otherwise studies can be loaded with Studies of the last n days/weeks or month. Load only the following studies loads only studies with the given criteria (consisting of a modality and study description). JiveX [rv] User Manual

98 Fig. 74: The Previous Study -tab 9.7 Subsequent use of hanging protocols Hanging protocols can be used subsequently.

For further information see the chapter "Configuration" of the server's user manual. JiveX [rv] User Manual

107 13 Troubleshooting 13.1 Login By default, the name of the current user will be displayed as a (pre-entered) input for the user text field of the login dialog box. Do disable this function and thereby leave the user input field blank initially, please enter the following command into the Java Runtime Environment: rv.login.usesystemlogin.enabled=false On Windows operating systems, this feature can easily be added to the section "[JVM_PROPERTIES] of the configuration file "RVStart.ini or "RVStartWS.ini. If unsure how to modify the configuration file please contact your system s administrator License warnings If all available licenses are in use, a window appears informing the user that the maximum number of available log-ons is about to be exceeded. Nevertheless the viewer can be used. Fig. 82: License warning If a diagnostic or demonstration client is started and there is no free license for that client type available, a standard ReviewClient license is acquired instead. Please note that all diagnostic or demonstration specific features are disabled in this case. If a review client is started and there is no free license for that client type available but there is a free diagnostic license available, this license is used instead. Please note that this may cause performance problems in that you can start less diagnostic clients than diagnostic licenses available, because some of the diagnostic licenses are used by normal review clients.

108 Fig. 83: Diagnostic license warning Insufficient Memory The client checks the memory available for the Java-VirtualMachine. If there is not enough memory available to start the client aborts logging in and shows an error message. Fig. 84: Insufficient memory error 13.2 Graphic Boards Grayscale Display If grayscale displays or graphic boards are used, the system setup should use a static grayscale palette with 256 colors. The according parameters can normally be entered in the driver of the graphic board. JiveX [rv] User Manual

109 Dual- and Multi-display Setups Connecting multiple displays to a single workstation system sometimes results in rendering problems on grayscale displays. Here, Java can force applications to be rendered in grayscale, by setting a (system-wide) environment property: FORCEGRAY=TRUE If unsure how to set system-wide environment properties, please contact your administrator Barco Medical Graphic Boards A known problem of BarcoMed graphic boards (3MPxxx, 5MPxxx) is the occasional incorrect display of cursor icons. To circumvent this problem on windows operating systems, please disable the video cursors. Barco can supply a registry patch to automate this. Please contact the Barco support for appropriate instructions and further details (image.care@barco.com or MedDevSupt@barco.com) DirectX Incompatibility In case of graphical problems of the JiveX [rv] or incompatible hardware to the Windows DirectDraw you can disable DirectDraw for the Java Virtual Machine. Note this should be only done with care because disabling the DirectDraw will cause reduced performance of JiveX [rv] (e.g. in the DICOM Viewer). To disable DirectDraw for Java, you can pass the property: sun.java2d.noddraw=true to the Java Virtual Machine. On Windows systems, this property can easily be added to the section [JVM_PROPERTIES] of the configuration file RVStart.ini or RVStartWS.ini. If unsure how to modify the configuration file, please contact your administrator Java Runtime Environment Font Loading For unknown reasons, sometimes the detection of installed system fonts during the startup of the Java Runtime Environment fails. So far, this problem has only been reported for Windows operating systems. You may get the following error message (see below): JiveX [rv] User Manual

110 Fig. 85: Font initializing problem As a result, the Java Runtime Environment does not start up and dies. The following instructions will circumvent this problem: To skip the system font initializing during startup, please pass the parameter com.visustt.xpstylepasswordfieldenabled=false to the Java Virtual Machine and try to run JiveX [rv] again. On Windows systems, this property can easily be added to the section "[JVM_PROPERTIES] of the configuration file "RVStart.ini or "RVStartWS.ini. If unsure how to modify the configuration file, please contact your administrator. JiveX [rv] User Manual
