C.4.2.1.4.2 Activity - Configured AE Makes Procedure Step Request​

When a configured remote AE sends a conformant association request including one of the Modality Performed Procedure Step​ Presentation Contexts in the table below then DICOMSRV will accept the Association.​

C.4.2.1.4.2.1 Description and Sequencing of Activities​

As mentioned above, DICOMSRV is started at system boot time and is thus ready to process MPPS messages at any time thereafter.​ The sequencing diagram below specifies a common flow of messages related to this activity. Prior to this sequence of messages it​ is necessary that orders have been received from the HIS interface or created via DICOMRis Ordering and Scheduling application.​ Attributes from the orders and created procedures, usually queried using MWL, will be included in the MPPS messages the Modality​ sendstoDICOMSRV.KeyattributesintheMPPSN-CREATEandN-SET,specifiedbelow,areextractedandmatchedagainstvalues​ in the DICOMRis database. A match allows full update of all applicable DICOMRis database tables.​

Page 148​

DICOM PS3.2 2020a - Conformance​

The figure above is a possible sequence of messages and events for the Configured AE Makes Procedure Step Request activity.​

1.​The Modality opens an Association to update DICOMSRV using MPPS​

2.​The Modality sends an N-CREATE Request to indicate that it is performing one or more Requested Procedures​

3.​The Modality performs all or part of the procedure(s)​

4.​DICOMSRV stores the MPPS and executes the matching algorithm described in the conformance section below. If a successful​ match is found, then updates to various tables per the N-CREATE are performed. See Table C.4.2-10 for additional detail. In the​ matching case, the procedure state of the procedure(s) referenced in the MPPS is updated if so configured​

5.​The Modality sends an N-SET setting the status of the MPPS to COMPLETED​

6.​DICOMSRV stores the MPPS. If the N-CREATE for this step matched then updates are performed as specified in step 4​

7.​The Modality closes the Association​

DICOMSRV also supports the 5 IHE Unidentified Patient Use Cases. Cases 1, 2 and 4 are transparent to the MPPS SCU and follow​ the normal flow. In case 3, the patient upon whom a given procedure must be immediately performed has been registered on the HIS​ and has a valid Patient ID but has no order specifying the applicable procedure. DICOMSRV recognizes this case when an MPPS​ N-CREATE is received with a matching Patient ID, zero-length Accession Number (0008,0050) and Requested Procedure ID​ (0040,1001). If the MPPS SCU is configured for support of IHE Trauma cases, DICOMSRV will order a procedure corresponding to​ the code contained in the Procedure Code Sequence (0008,1032), if this code is recognized, or will order a default procedure based​ on configuration. If the default procedure is ordered then a user may modify the procedure using DICOMRis Ordering and Scheduling​ application.​

In case 5, there is no existing registration or order for a patient on whom a procedure must be immediately performed. Values are​ enteredontheModalityidentifyingthepatientandprocedure.DICOMSRVrecognizesthiscasewhenanMPPSN-CREATEisreceived​ containing a Patient ID within a configured range. This range will never contain Patient IDs created in the normal flow. If the MPPS​ SCU is configured for support of IHE Trauma cases, DICOMSRV will register the patient with the Patient ID provided and will order​ a procedure as described above.​

C.4.2.1.4.2.3 SOP Specific Conformance for MPPS SOP Class​

The table below lists all Modality Performed Procedure Step attributes, whether they may be created by N-CREATE and updated by​ N-SET and what parts of the DICOMRis database they are used to update. All MPPS messages and thus their attributes are stored​ for the configurable Purge Period described below. The 'Database Updates' column considers updates separate from the storage of​ MPPS messages. If no value is present this indicates that there are is no update to the database associated with the given element.​
