2.2.4.3.1.3 SOP Specific Conformance – MPPS (1.2.840.10008.3.1.2.3.3)
"Workstation" (SCU) can send the following DIMSE services:
· N-CREATE
· N-SET
A N-CREATE allows "Workstation" to create an instance of the Modality Performed Procedure Step SOP
Class and provide information about a specific real-world Performed Procedure Step that is under control of
"Workstation".
A N-SET allows "Workstation" to set Attribute Values of an instance of the Modality Performed Procedure
Step SOP Class and provide information about a specific real-world Modality Performed Procedure Step that
is under control of "Workstation".
Note:
"Workstation" informs the Information System as soon as possible that the performance of the Procedure Step
has been started by sending the N-CREATE Service Request. This allows an SCP of the Modality Worklist SOP
Class (if supported) to update the Modality Worklist. Some of the attribute values are already known at the
beginning of the Procedure Step, they are sent in the N-CREATE command. Other mandatory attributes are
known only at the end of the Performed Procedure Step, they are assigned a value in the NSET command.
The behavior of MPPS AE when encountering status codes in an MPPS N-CREATE or N-SET response is
summarized in the Table below:
