6 The application provides a user interface, internal database and network listener. Conceptually the network services may be modeled as the following separate AEs, though in fact all the AEs share a single (configurable) AE Title: - ECHO-SCP, which responds to verification requests - ECHO-SCU, which sends verification requests to remote AEs - STORAGE-SCP, which stores incoming images in the local storage - STORAGE-SCU, which sends images to remote AEs - FIND-SCP, which responds to queries from remote AEs with matching lists of studies, series and instances - FIND-SCU, which queries remote AEs for matching lists of studies, series and instances - MOVE-SCP, which moves specified studies, series or instances to remote AEs - MOVE-SCU, which retrieves selected studies, series or instances Functional Definitions of AE s ECHO-SCP ECHO-SCP waits in the background for connections, will accept associations with Presentation Contexts for SOP Class of the Verification Service Class, and will respond successfully to echo requests ECHO-SCU ECHO-SCU is activated through the user interface when a user wants to verify if a certain remote AE accepts associations with Presentation Contexts for SOP Class of the Verification Service Class STORAGE-SCP STORAGE-SCP waits in the background for connections, will accept associations with Presentation Contexts for SOP Classes of the Storage Service Class, and will store the received instances to the local database where they may subsequently be listed and viewed through the user interface STORAGE-SCU STORAGE-SCU is activated through the user interface when a user selects instances from the local database and requests that they are sent to a remote AE (selected from a pre-configured list) FIND-SCP FIND-SCP waits in the background for connections. It will query the application s local database for matching studies, series and instances according to the level requested by the remote AE. The results will be sent back to the remote AE FIND-SCU FIND-SCU is activated through the user interface when a user selects a remote AE to query (from a pre-configured list), then initiates a query. Queries are performed recursively from the study through the series and instance levels until all matching instances have been listed MOVE-SCP MOVE-SCP waits in the background for connections. It will query the application s local database for the specified studies, series and instances according to the level requested by the remote AE. The instances will be sent to the destination AE on a separate association using the STORAGE-SCU functionality.

7 MOVE-SCU MOVE-SCU is activated through the user interface when a user selects a study, series or instance for retrieval. A connection to the remote AE is established to initiate and monitor the retrieval and the STORAGE-SCP AE receives the retrieved instances. 2.2 AE SPECIFICATIONS ECHO-SCP SOP Classes ECHO-SCP provide Standard Conformance to the following SOP Class(es): Table SOP CLASSES SUPPORTED BY ECHO-SCP SOP Class Name SOP Class UID SCU SCP Verification SOP Class No Yes Association Policies General ECHO-SCP accepts but never initiates associations MAXIMUM PDU SIZE RECEIVED AS A SCP FOR ECHO-SCP Maximum PDU size received Unlimited Number of Associations NUMBER OF ASSOCIATIONS AS A SCP FOR ECHO-SCP Maximum number of simultaneous associations Unlimited Asynchronous Nature ECHO-SCP will only allow a single outstanding operation on an Association.

16 FIND-SCU provides standard conformance to the supported C-FIND SOP Classes. Only a single information model, Study Root, is supported. All queries are initiated to the level of the information model (STUDY, SERIES or IMAGE level) selected by the user in the application user interface. Initially the user queries for studies (STUDY level) to list all the studies that match the filter fields (e.g. Patient Last Name, Modality, etc) selected by the user in the user interface. The lower levels (series and images) will be not retrieved automatically for all the studies for performance reasons; the series will be listed when the user selects a listed study. The images are listed when the user selects a listed series. No CANCEL requests are ever issued. Requested return attributes not returned by the SCP are ignored. Non-matching responses returned by the SCP due to unsupported (hopefully optional) matching keys are not filtered locally by the FIND-SCU and thus will still be presented in the user interface. No attempt is made to filter out duplicate responses.

MOVE-SCU completely ignores whatever activities are taking place in relation to the STORAGE-SCP AE that is receiving the retrieved instances. Once the C-MOVE has been initiated it runs to completion (or failure) as described in the C-MOVE response command message(s). There is no attempt by MOVE-SCU to confirm that instances have actually been successfully received or locally stored. Whether or not completely or partially successfully retrievals are made available in the local database to the user is purely dependent on the success or failure of the C-STORE sub-operations, not on any explicit action by MOVE-SCU. Whether or not the remote AE attempts to retry any failed C-STORE sub-operations is beyond the control of MOVE-SCU. If the association on which the C-MOVE was issued is aborted for any reason, whether or not the C- STORE sub-operations continue is dependent on the remote AE; the local STORAGE-SCP will continue to accept associations and storage operations regardless Association Acceptance Policy MOVE-SCU does not accept associations.

It acts as an SCU of the DICOM print management SOP class Functional Definitions of AE s PRINT-SCU DICOM Print SCU establishes the Association with the requested printer to print the composed film. If the Remote AE accepts the presentation context applicable to the print job, the DICOM Print AE SCU will send the print job to the receiving Remote AE by using the N- CREATE and N-SET services Sequencing of Real-World Activities The user will select the DICOM printer from the User Interface. The images to be printed will be selected in the Viewing application. The user can print either

28 grayscale, either color images, but cannot mix grayscale and color images in a session. The Print SCU will start the Print Session which involves the following sequence of activities. The Print SCU establishes the DICOM association with the printer. The Print SCU gets the Printer status using the N-GET service. If the Printer returns FAILURE status the print session will be terminated. The Print SCU sends a request to the printer to create the film session using the N-CREATE service. In case of error the print session will be terminated. The attribute values for the Film session will be specified with the film session request. The Print SCU sends a request to the printer to create the film box using the N-CREATE service. The print session will be terminated if the printer fails to create the film box. The film box attribute values will be sent in the film box create request. The image attributes for the images to be printed in this session will be set using the N-SET service. If the printer fails to accommodate the images in the image set to be printed the print session will be terminated and the user notified. The Print SCU sends a request to the printer to print the film using the N-ACTION service. Only film box printing is supported. In case of error the print session will be terminated. The Print SCU sends a request to the printer to delete the film box instance using the N- DELETE service. The SCU does not wait for N-EVENT-REPORT from Printer. The association will be terminated. A successful print session just indicates the images to be printed have been successfully sent to the printer. 4.2 AE SPECIFICATIONS SOP Classes PRINT-SCU provide Standard Conformance to the following SOP Class(es): Table SOP CLASSES SUPPORTED BY PRINT-SCU SOP Class Name SOP Class UID SCU SCP Basic Grayscale Print Management Yes No Meta SOP Class Basic Color Print Management Yes No Meta SOP Class Printer SOP Class Yes No Association Policies General PRINT-SCU initiates but never accepts associations.

The supported attributes for the Film Session creation are: Attribute Number Of Copies (2000, 0010) Print Priority (2000, 0020) Medium Type (2000, 0030) Film Destination (2000, 0040) DICOM Tag If N-CREATE fails the association will be terminated Basic Film Box SOP Class The PRINT-SCU will create a basic film box using the N-CREATE DIMSE service. The supported attributes for the Film Box creation are: Attribute Image Display Format (2010, 0010) Film Orientation (2010, 0040) Film Size ID (2010, 0050) Border Density (2010, 0100) Empty Image Density (2010,0110) Referenced Film Session Sequence (2010,0500) >Referenced SOP Class UID (0008,1150) >Referenced SOP Instance UID (0008,1155) DICOM Tag If N-CREATE fails the association will be terminated. The PRINT-SCU will print the basic film box using the N-ACTION DIMSE service. If N- ACTION fails the association will be terminated. The PRINT-SCU will delete the basic film box using the N-DELETE DIMSE service. If N- DELETE fails the association will be terminated Basic Grayscale Image SOP Class The PRINT-SCU will set the image box attributes created by the basic film box using the N- SET DIMSE service. The supported attributes are:

If the failure message indicates that the image(s) sent to the printer don t fit the film box, the user will be notified Basic Color Image SOP Class The PRINT-SCU will set the image box attributes created by the basic film box using the N- SET DIMSE service. The supported attributes are: Attribute Image Position (2020,0010) Preformatted Color Image Sequence (2020,0111) >Samples Per Pixel (2028,0002) >Photometric Interpretation (2028,0004) >Planar Configuration (2028,0006) >Rows (2028,0010) >Columns (2028,0011) >Pixel Aspect Ratio (2028,0034) >Bits Allocated (2028,0028) >Bits Stored (2028,0101) >High Bit (2028,0102) >Pixel Representation (2028,0103) DICOM Tag If N-SET fails the association will be terminated. If the failure message indicates that the image(s) sent to the printer don t fit the film box, the user will be notified Printer SOP Class The PRINT-SCU will get the printer status using the N-GET DIMSE service. If N-GET fails the association will be terminated. The PRINT-SCU will examine the returned printer status and will take the following actions: Printer Printer Status Action Status Information NORMAL N/A Continue printing WARNING RECEIVER FULL The association will be terminated SUPPLY EMPTY The association will be terminated
