Implementation Model of dicompacs Viewer 2.2. Functional Definitions of AEs dicomcc is the main control process of dicompacs. It implements the following service classes: DICOM Verification Service Class (SCP) DICOM Storage Service Class (SCU and SCP) DICOM Query/Retrieve (SCP) DICOM Storage Commitment (SCP) WL-Server is an application entity which implements the DICOM Modality Worklist service class as SCP. ORPrintSCU implements the Basic Grayscale Print Management service class as SCU. The process is used by dicompacs Viewer to send print jobs to DICOM printers. PrintSCP implements the Basic Grayscale Print Management service classes as SCP. It is used to redirect DICOM prints to a standard system printer. The dicompacs Viewer is able to send query/retrieve requests to other DICOM AE s. It starts a storage SCP together with a retrieve request. Received images are imported into the viewer. Retrieved images may be archived by the user manually. All AE s which implement SCP functions do respond on C-Echo requestes. DICOM Conformance Statement dicompacs 5 - Rev. 005 Page 6 of 21

9 3.2. DicomCC General dicomcc accepts an association when it receives an association request from a remote DICOM AE which contains at least one supported presentation context. The support of SOP classes may be disabled by the configuration or license limitations.. It accepts incoming association requests on a set of port numbers defined in the configuration file. The maximum PDU length can be configured in the range bytes. The default is bytes. There is no enforced limit on number of associations of the SCP function. System configuration (CPU, memory, Disk) may enforce practical limitations. The maximum number of connections is configurable. dicomcc does not support asynchronous transactions Send Image (StoreSCU) dicomcc will attempt to establish an association whenever an image was received by StoreSCP and if a forward rule exists. dicomcc also handles manual send requests initiated by a user via the dicompacs -Viewer. The StoreSCU function will attempt only one association establishment at a time. The default behaviour of the Store SCU is to propose the SOP class of the images to be sent in combination with the Implicit VR Little Endian transfer syntax and one of the other supported transfer syntaxes (see section 3.1.2). The transfer syntax is selected according to the definition in the configuration file. The Implicite Little Endian VR transfer syntax will always be the last in the list of the proposed transfer syntaxes Receive Echo (EchoSCP) The EchoSCP function sends a C-Echo response to the calling AE. dicompacs 5 will accept any presentation context containing the Verification SOP class and following transfer syntax: Name UID Name List UID List Negotiat Verification Implicit VR Little Endian SCP none Receive Image (StoreSCP) The StoreSCP function conforms to the Storage Service Class at Level 2 (Full). No elements are discarded or coerced. In the event of a successful C-STORE operation, the image has been written successfully to the incoming data pool. The following processing forwards the image files to predefined destinations and archives it in the image database. After archiving the images are available for viewing. StoreSCP function supports transfer syntaxes listed in section It prefers to receive images encoded in lossless compressed transfer syntax. Extended negotiations are not supported. If inserting of images into the incoming data pool fails then association is aborted and a suitable error code is returned. DICOM Conformance Statement dicompacs 5 - Rev. 005 Page 9 of 21

10 Association requests can be rejected with the following status codes and reasons: Result Source Reason Description rejected permanent provider, present. related temporary congestion Resource limitation: thread creation Failed, memory failure, limited local disk space rejected user app. context name not Incorrect application context name transient rejected permanent supported user no reason Unknown AE-Titles, hostnames or IP addresses The following error/warning status codes can be sent by the Store SCP in the context of a C-STORE-RSP message: Code Name Severity Description a700 refused: out of resources failure Application out of memory, file system or database write error (e. g. full) a800 refused: SOP class failure Received C-STORE-RQ for non-storage SOP class not supported a900 error: data set does not match SOP class failure SOP class or instance UID in C-STORE-RQ does not match UIDs in the received dataset c000 error: cannot understand failure Received dataset without SOP class or instance UID; received Presentation State that failed syntax check; internal application error Query images (FindSCP) dicomcc conforms to the C-Find service class baseline behaviour. It does not support extended negotiation nor priority processing. dicomcc can limit the number of response datasets if a search on patient or study level is performed. The maximum number is configurable in the configuration file. The function supports following presentation contexts: Name UID Name List UID List Negotia Patient Root Query/ Implicit VR Little Endian SCP none Retrieve SCP none Information Model - FIND SCP none Patient Root Query/ Retrieve Information Model - FIND Patient/Study Only Query/Retrieve Information Model - FIND Implicit VR Little Endian SCP none SCP none SCP none Implicit VR Little Endian SCP none SCP none SCP none The software supports matching and retrieval of some optional attributes. The following table list all supported attributes while the column Type has following meanings: Type Meaning Type Meaning U Unique key - Matching is supported R Key can be returned but no M Matching is supported matching is performed Attribute Tag Type Patient Level Attributes Patient Name (0010,0010) M Patient ID (0010,0020) U Patient Birth Date (0010,0030) M DICOM Conformance Statement dicompacs 5 - Rev. 005 Page 10 of 21

The AE must be configured in the configuration file. dicomcc supports following presentation contexts: Name UID Name List UID List Negot. Patient Root Query/ Retrieve Information Model - MOVE Patient Root Query/ Retrieve Information Model - MOVE Patient/Study Only Query/Retrieve Information Model - MOVE Implicit VR Little Endian SCP none Implicit VR Little Endian SCP none Implicit VR Little Endian SCP none Storage Commitment (SC-SCP) dicomcc handles Storage commitment request as follows: - N-ACTION request is accepted from all AEs which are defined in the configuration file (with AE-Title, hostname and port). All other requests are rejected. - dicomcc send response for the N-ACTION request. - dicompacs database is searched for requested SOP instances - dicomcc establish a new association to the AE and sends N-EVENT-REPORT. The SCU must be able to handle the request for a separate association. DICOM Conformance Statement dicompacs 5 - Rev. 005 Page 11 of 21

12 dicomcc supports following presentation context for Storage Commitment: Name UID Name List UID List Negot. Storage Commitment Push Model Implicit VR Little Endian SCP none In default configuration dicomcc does not delete SOP instances. If no space is available for new images then C-STORE requests are rejected. dicomcc can be configured to remove eldest images if the system runs out of storage capacity. Application profiles, Storage Media File-Set ID and UID attributes are not supported.

19 dicompacs -Viewer starts the SCP feature during the application startup if at least one query/retrieve destination is defined and the appropriate license is available. The SCP feature is supposed to receive data requested by DICOM Retrieve. All received images are stored in a local filesystem folder and imported by the viewer. dicompacs -Viewer accepts an association when it receives an association request from a remote DICOM Storage or Verification SCU which contains at least one supported presentation context. It accepts incoming association requests on a set of port numbers defined in the configuration file. The maximum PDU length can be configured in the range bytes. The default is bytes.there is no enforced limit on number of associations of the SCP function. System configuration (CPU, memory, Disk) may enforce practical limitations.
