Application Context Name​

F.4.2.2.2.2 Number of Associations​

 

TheQUERY-RETRIEVE-SCPAEcansupportmultiplesimultaneousAssociations.EachtimetheQUERY-RETRIEVE-SCPAEreceives​ an Association, a child process will be spawned to process the Verification, Query, or Retrieval request. The maximum number of​ child processes, and thus the maximum number of simultaneous Associations that can be processed, is set by configuration. The​ default maximum is 10 in total. The maximum number of simultaneous Associations can be either an absolute number or a maximum​ number for each requesting external Application Entity. The latter flexibility can be useful if communication with one external AE is​ unreliable and one does not wish 'hung' connections with this AE to prevent Associations with other client AEs.​

10 (Configurable)​

F.4.2.2.2.3 Asynchronous Nature​

 

The QUERY-RETRIEVE-SCP AE does not support asynchronous communication (multiple outstanding transactions over a single​ Association). All Association requests must be completed and acknowledged before a new operation can be initiated.​

NotethattheSTORAGE-SCUAE,andQUERY-RETRIEVE-SCPAEusethesameImplementationClassUID.AllEXAMPLE-QUERY-​ RETRIEVE-SERVER AEs use the same Implementation Version Name. This Version Name is updated with each new release of the​ product software, as the different AE versions are never released independently.​

F.4.2.2.3 Association Initiation Policy​

The QUERY-RETRIEVE-SCP AE does not initiate Associations.​

F.4.2.2.4 Association Acceptance Policy​

F.4.2.2.4.1 Activity - Handling Query and Retrieval Requests​

F.4.2.2.4.1.1 Description and Sequencing of Activity​

The QUERY-RETRIEVE-SCP AE accepts Associations only if they have valid Presentation Contexts. If none of the requested​ Presentation Contexts are accepted then the Association Request itself is rejected. It can be configured to only accept Associations​ with certain hosts (using TCP/IP address) and/or Application Entity Titles.​

If QUERY-RETRIEVE-SCP AE receives a query (C-FIND) request then the response(s) will be sent over the same Association used​ to send the C-FIND-Request.​

If QUERY-RETRIEVE-SCP AE receives a retrieval (C-MOVE) request then the responses will be sent over the same Association​ used to send the C-MOVE-Request. The QUERY-RETRIEVE-SCP AE will notify the STORAGE-SCU to send the requested SOP​ Instances to the C-MOVE Destination. The STORAGE-SCU AE notifies the QUERY-RETRIEVE-SCP AE of the success or failure of​ each attempt to send a Composite SOP Instance to the peer C-MOVE Destination AE. The QUERY-RETRIEVE-SCP AE then sends​

- Standard -​

DICOM PS3.2 2020a - Conformance​

Page 237​

a C-MOVE Response indicating this status after each attempt. Once the STORAGE-SCU AE has finished attempting to transfer all​ the requested SOP Instances, the QUERY-RETRIEVE-SCP AE sends a final C-MOVE Response indicating the overall status of the​ attempted retrieval.​

Figure F.4.2-2. Sequencing of Activity - Handling Query and Retrieval Requests​

The following sequencing constraints illustrated in Figure F.4.2-2 apply to the QUERY-RETRIEVE-SCP AE for handling queries (C-​ FIND-Requests) :​

1.​Peer AE opens an Association with the QUERY-RETRIEVE-SCP AE.​

2.​Peer AE sends a C-FIND-RQ Message​

3.​QUERY-RETRIEVE-SCP AE returns a C-FIND-RSP Message to the peer AE with matching information. A C-FIND-RSP is sent​ for each entity matching the identifier specified in the C-FIND-RQ. A final C-FIND-RSP is sent indicating that the matching is​ complete.​

4.​Peer AE closes the Association. Note that the peer AE does not have to close the Association immediately. Further C-FIND or​ C-MOVE Requests can be sent over the Association before it is closed.​

The following sequencing constraints illustrated in Figure F.4.2-2 apply to the QUERY-RETRIEVE-SCP AE for handling retrievals (C-​

3.​QUERY-RETRIEVE-SCP AE notifies the STORAGE-SCU AE to send the Composite SOP Instances to the peer C-MOVE Des-​ tination AE as indicated in the C-MOVE-RQ.​

4.​After attempting to send a SOP Instance, the STORAGE-SCU AE indicates to the QUERY-RETRIEVE-SCP AE whether the​ transfer succeeded or failed. The QUERY-RETRIEVE-SCP AE then returns a C-MOVE-RSP indicating this success or failure.​

5.​Once the STORAGE-SCU AE has completed all attempts to transfer the SOP Instances to the C-MOVE Destination AE, or the​ first failure occurred, the QUERY-RETRIEVE-SCP AE sends a final C-MOVE-RSP indicating the overall success or failure of the​ retrieval.​

6.​Peer AE closes the Association. Note that the peer AE does not have to close the Association immediately. Further C-FIND or​ C-MOVE Requests can be sent over the Association before it is closed.​

The QUERY-RETRIEVE-SCP AE may reject Association attempts as shown in the table below. The Result, Source and Reason/Diag​ columns represent the values returned in the corresponding fields of an ASSOCIATE-RJ PDU (see Section 9.3.4 “A-ASSOCIATE-​ RJ PDU Structure” in PS3.8). The following abbreviations are used in the Source column:​

a.​1 - DICOM UL service-user​

b.​2 - DICOM UL service-provider (ASCE related function)​

c.​3 - DICOM UL service-provider (Presentation related function)​

F.4.2.2.4.1.3 SOP Specific Conformance for Query SOP Classes​

The QUERY-RETRIEVE-SCP AE supports hierarchical queries and not relational queries. There are no attributes always returned​ bydefault.Onlythoseattributesrequestedinthequeryidentifierarereturned.QueryresponsesalwaysreturnvaluesfromtheEXAMPLE-​ QUERY-RETRIEVE-SERVER database. Exported SOP Instances are always updated with the latest values in the database prior to​ export. Thus, a change in Patient demographic information will be contained in both the C-FIND Responses and any Composite SOP​ Instances exported to a C-MOVE Destination AE.​

Patient Root Information Model​

All required search keys on each of the four levels (Patient, Study, Series, and Image) are supported. However, the Patient ID​ (0010,0020) key must have at least a partial value if the Patient's Name (0010,0010) is not present in a Patient Level query.​

Study Root Information Model​

All the required search keys on each of the three levels (Study, Series, and Image) are supported. If no partial values are specified​ for Study attributes then either the Patient ID (0010,0020) key or the Patient's Name (0010,0010) must have at least a partial value​ specified.​
