14 4. Functional definition of AEs FluoroPRO DICOM functionality described above is spread over the following applications: STORE_SCP (a C-STORE SCP), STORE_SCU (ac-store SCU), a C- STORE SCU in response to C-MOVE requests from a remote Query retrieve SCU), QR_CLIENT (a Query Retrieve C-MOVE and C-FIND SCU), WORK_SCU (a Modality Worklist C-FIND SCU), PRINT_SCU (a DICOM Print SCU), and MEDIA STORAGE. 4.1 STORE_SCP AE: STORE_SCP can operate as a command line application or as a Windows NT Service, and provides C-STORE SCP functionality to FluoroPRO. Generally STORE_SCP is configured to begin automatically on system startup and run continuously until shutdown. As a SCP for C-STORE, FluoroPRO listens for storage proposals from remote AEs. Following acceptance by FluoroPRO of an association request from a remote AE, the remote AE transmits the DICOM Information Objects to FluoroPRO. FluoroPRO stores the received Information Object and updates its database. A response is sent to the remote AE indicating the result status of the storage operation. STORE_SCP also functions as a SCP for C-ECHO, and as such listens for communication verification requests from remote AEs, and replies with the C-ECHO response. 4.2 STORE_SCU AE: can operate as a command line application or as a Windows NT Service, and provides C-STORE SCU functionality to FluoroPRO. As a SCU for C-STORE, a user interface command causes FluoroPRO to request an association with a remote system. Following acceptance of the association by the remote system, FluoroPRO transmits the DICOM Information Objects. FluoroPRO returns the result status of the storage request to the user interface accordingly. 4.3 QR CLIENT AE: QR_CLIENT is a windows application that provides C-FIND SCU and C-MOVE SCU functionality to FluoroPRO. As an SCU for C-FIND, a user interface command causes FluoroPRO to request an association with a remote system. Following acceptance of the association by the remote system, FluoroPRO transmits the DICOM Query requests. The remote system returns the matches as DICOM Query responses to FluoroPRO, which displays them in the user interface. As a SCU for C-MOVE, a user interface command causes FluoroPRO to request an association with a remote system. Following acceptance of the association by the remote system, FluoroPRO transmits the DICOM Retrieve requests to the remote system. If a C-MOVE is requested, FluoroPRO will wait for a final response from the remote system returns which it displays the in the user interface. Version 1.1 Page 14 of th Feb 28

15 4.4 PRINT_SCU AE: PRINT_SCU can operate as a command line application or as a Windows NT Service, and provides DICOM Print SCU functionality to FluoroPRO. Images are preformatted by the CADRAN Viewer application, and a request to print them submitted. PRINT_SCU interrogates this print request list and sends the requested pages to the remote Basic Print SCP. PRINT_SCU waits for Print Job status reports from the remote Print SCP, and updates local the records of Print Job Status accordingly. 4.5 WORK_SCU AE: WORK_SCU is a windows application that provides Modality Worklist C-FIND SCU to CADRAN applications. As an SCU for C-FIND, a user interface command causes a request for an association with a remote system. Following acceptance of the association by the remote system, FluoroPRO transmits the DICOM Query requests. The remote system returns the matches as DICOM Query responses to FluoroPRO, which displays them in the user interface. 4.6 MEDIA STORAGE AE: The Media Storage AE can perform the following functions: It can initialize a piece of media, writing a new DICOM File-set onto the media. It can display a directory listing of the File-set on a piece of media. It can copy SOP instances from the media onto local storage. 5. Sequencing of Real World Activities NA 6. File Meta Information Options Implementation Class UID = Implementation Version = CADRAN_21 The Implementation Class UID is part of the File Meta Information written into every file and therefore necessary for any device that acts as an FSC.

16 7. AE Specifications 7.1 STORE_SCP AE Specification The STORE_SCP AE provides Standard Conformance to the DICOM V3. SOP Classes listed in Table 1 as an SCP. Note that the STORE_SCP AE is highly configurable, and as such not all classes in the list may be accepted when using the default configuration, i.e. configuration changes may be required (see section 1). Table 1 SOP Class UID SOP Class Verification SOP Class Secondary Capture Image Storage Multi-Frame Greyscale Byte Secondary Capture Image Storage Multi-Frame Greyscale Word Secondary Capture Image Storage Multi-Frame True Colour Secondary Capture Image Storage Standard Xray Angio Standard Xray RF Association establishment policies General The AE Title of the STORE_SCP AE is a configurable parameter. The default title is FP_ST_SCP. The STORE_SCP AE waits for an association as an SCP of the Storage Services. The maximum PDU size is configurable from a minimum of 4,96 bytes Number of Associations The STORE_SCP AE will handled up to 5 storage SCP associations simultaneously Asynchronous nature The STORE_SCP AE does not support asynchronous operations Implementation Identifying Information The Implementation Class Unique Identifier (UID) for the STORE_SCP AE is: The Implementation version name for the STORE_SCP AE is: CADRAN_21 Version 1.1 Page 16 of th Feb 28

17 Association initiation policy The AE Title of the STORE_SCP AE is a configurable parameter. The default title is FP_ST_SCP. STORE_SCP AE will attempt to establish an association to a remote Storage Commit SCU to facilitate a N-EVENT-REPORT reply to a N-ACTION Storage Commit request. The maximum PDU size is configurable from a minimum of 4,96 bytes Association acceptance policy The STORE_SCP AE accepts associations for the store and verification services Real World Activity Receive Echo Associated Real-World Activity Reply to Echo Request The associated activity is a C-ECHO request Proposed Presentation Contexts The STORE_SCP AE will propose Presentation Contexts as shown in Table 2.

Following acceptance of the association the STORE_SCP AE receives the images on the open association. The internal database is updated on transfer of each image. An appropriate response is returned. Version 1.1 Page 17 of th Feb 28

18 Accepted Presentation Contexts STORE_SCP AE will accept presentation contexts as shown in Table 3. Note that configuration changes (as outlined in section 1) may be required for STORE_SCP to accept a paticular Abstract Syntax/Transfer Syntax pair. Note that when STORE_SCP receives an uncompressed image of implicit little endian or explicit big endian, it is synchronously transformed to explicit little endian before storage. Uncompressed X- ray angio images (Abstract syntax UID ) are asynchronously transformed to transfer syntax JPEG lossless Hier14 (UID ) before storage. Images of all other transfer syntaxes are stored in the transfer syntax in which they are received.

21 Implementation Identifying Information The Implementation Class Unique Identifier (UID) for the STORE_SCU AE is: The Implementation version name for the STORE_SCU AE is: CADRAN_ Association initiation policy The STORE_SCU AE attempts to initiate an association for the following real world activity: Send images from STORE_SCU AE to a Remote AE Association acceptance policy The STORE_SCU AE does not accept associations Real World Activity Send Images to Remote AE Associated Real-World Activity The associated real-world activity is a C-STORE Request initiated by the user when images are selected for transfer to a remote AE Manual Operation The user selects the remote system and image sets to transfer in the user interface. Committing the transfer causes STORE_SCU AE to initiate an association with the remote AE for a C-STORE request System Operation In certain situations, STORE_SCU AE will initiate an asociation within a user request for a remote system for a C-STORE request Proposed Presentation Contexts STORE_SCU AE will accept presentation contexts as shown in Table 6. Note that FluoroPRO is not capable of translating to or from a particular encapsulated transfer syntax. If an image is received by the STORE_SCP in a given encapsulated transfer syntax, it can only be sent by the STORE_SCU in that same transfer syntax. STORE_SCU can freely translate between explicit little endian, implicit little endian and explicit big endian transfer syntaxes.

The association is aborted should a time-out occur Association Acceptance Policy PRINT_SCU does not accept associations Real World Activity Printing of DICOM images on a Remote AE Associated Real-World Activity Once the Print Image association has been established, PRINT_SCU, sends a Basic Film Session, N_CREATE message to the Basic Print SCP. This is followed by an Basic Film Box, N_CREATE message. The PRINT_SCU then sends a Basic Grayscale Image Box, N_SET message. Finally, an N_ACTION message is sent to instruct the Basic Print SCP to print either at the Basic Film Session (if collation is supported by the remote SCP) or at the Basic Film Box level (if collation is not supported). While the association with the remote SCP is open, PRINT_SCU will listen for and process N_EVENT_REPORT messages from the remote SCP. If the remote SCP supports the Print Job SOP Class, then the SCU will periodically poll the remote SCP for Print Job Status reports until all submitted print jobs are finished Proposed Presentation Contexts PRINT_SCU AE will propose presentation contexts as shown in Table 13.

35 1. Configuration The FluoroPRO products obtains their configuration information from the following files: merge.ini - Identifies the other three configuration files and also contains message logging parameters. The location of this file is specified by specific register settings, which may be set as described in the operator s manual. mergecom.pro - Defines run-time parameters for FluoroPRO product applications, such as the network timeouts and PDU size, etc. Most parameters in this file should never be changed, as doing so could disrupt the DICOM interface conformance. mergecom.app Defines applications on other network nodes (such as supported image types, transfer syntaxes, application entities, etc.) to which connections are possible. mergecom.srv - Service and sequence definitions. This file does not need to be altered, as long as standard DICOM image types are transferred. Most parameters in this file should never be changed, as doing so could disrupt the DICOM interface conformance. Database network nodes can also be defined within the database to which the application is connected. 11.

37 The Offline-Media Application Entity supports the SOP Classes and Transfer Syntaxes listed in the Table below: Table 2 Information Object Definition Media Storage Directory Storage X-Ray Radio Fluoroscopic Image Storage SOP Class UID Transfer Syntax Explicit VR Little Endian Explicit VR Little Endian Transfer Syntax UID AE Title / Presentation Address Mapping Presentation address mapping for remote SCP s is configured in the mergecom.app file. This is where the Host, Port Number, and Application Title map an Application Entity (AE) Title to a Presentation Address in TCP/IP for the provider to which you wish to connect is stored. The Presentation Address of local SCP and SCU s is defined as shown in the FluoroPRO products operation manuals. Note: The host name maps to an IP address as specified by your host table. Generally port 14 should be used for standard connectivity; since this is the well-defined port for a DICOM server. 13. Support of Extended Character Sets Not supported. 14.
