2.2.4.3.1.2Proposed Presentation Contexts

The MPPS Application Entity is capable of proposing the Presentation Contexts shown in the following table:

2.2.4.3.1.3SOP 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-CREATEallows "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-SETallows "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:

Table 2.2-53: N-CREATE/N-SET Response Status Handling Behavior

Service	Further Meaning	Status Code	Behavior
Status
Success	Matching is complete	0000	The SCP has completed the operation successfully
Failure	Processing Failure –	0110H
