Figure 12: SEQUENCING OF ACTIVITY – HANDLING MODALITY WORKLIST QUERY REQUESTS
The following sequencing constraints illustrated in Figure 12 apply to the MODALITY-WORKLIST-SCP
AE for handling Modality Worklist queries (C-FIND-Requests):
1.
2.
3.
4.
Partner AE opens an Association with the MODALITY-WORKLIST-SCP AE.
Partner AE sends a C-FIND-RQ Message.
MODALITY-WORKLIST-SCP AE returns a C-FIND-RSP Message to the Partner AE with matching
information. A C-FIND-RSP is sent for each entity matching the identifier specified in the C-FIND-RQ.
MODALITY-WORKLIST-SCP AE checks for a C-FIND Cancel Request after each sent Pending
response message. If a Cancel is received then no further Pending responses are sent. A final CFIND-RSP is sent indicating that the matching is complete or the query was canceled.
Partner AE closes the Association. Note that the Partner AE does not have to close the Association
immediately. Further C-FIND Requests can be sent over the Association before it is closed.
The MODALITY-WORKLIST-SCP AE may reject Association attempts as shown in Table 70. The Result,
Source and Reason/Diag columns represent the values returned in the corresponding fields of an
ASSOCIATE-RJ PDU (see PS 3.8, Section 9.3.4). The following abbreviations are used in the Source
column:
d. 1 – DICOM UL service-user
e. 2 – DICOM UL service-provider (ASCE related function)
f. 3 – DICOM UL service-provider (Presentation related function)
