DICOM PS3.4 2024e - Service Class Specifications |

This Annex defines the Procedure Step SOP Classes.
This Annex formerly defined a Study Management Service Class that has been retired. See PS 3.4-2004.
The state information related to the Modality Performed Procedure Step is specified by the Modality Performed Procedure Step IOD in the Attribute Performed Procedure Step Status (0040,0252).
The Performed Procedure Step Object represents only the "performed" segment of the real-world procedure step and not the "scheduled" segment. The number of events is therefore limited; all events are initiated by the modality. The state "DISCONTINUED" means canceled or unsuccessfully terminated, which may happen when the performance of a Procedure Step has been started but cannot be finished by the modality. The modality shall convey this state change to the information system (the SCP), to allow the information system to reschedule or cancel the related Procedure Step. The state "COMPLETED" means that the acquisition of Composite SOP Instances has been successfully completed and the SCU has provided all required Attribute Values for the Performed Procedure Step.
Table F.1-3 describes the valid Modality Performed Procedure Step states.
Table F.1-4 defines the valid state transitions for the Performed Procedure Steps. For each of the above defined states the valid state resulting from the occurrence of events is specified. These state transitions are managed by the Modality Performed Procedure Step SOP Class.
