5 DICOM Storage Commitment SCU Conformance
5.1 Introduction
This section of the DICOM conformance statement specifies the Storage Commitment Push
Model SOP class as user, the optional attributes and service elements supported.
5.2 Implementation Model
5.2.1 Application data flow diagram
Illustration 5.1.1 shows the data flow diagram of Storage Commitment SCU. There is only one
Real-World activity that will cause the DICOM Server Application Entity (DICOM Server AE) to
initiate an association to a remote DICOM entity that is a Service Class Provider (SCP) of the
Storage Commitment SOP class.
The Choose Archive save Option Real-World activity consists of an operator choosing a remote
DICOM AE that supports Storage Commitment as provider as the archive device and selecting
one or more exam or series from the local database and choosing either Save Exam or Save
Series from the archive menu. The images to be committed are sent to the remote provider
entity first. The Commitment request for the transferred image instances is sent after the
complete image transfer. The Commitment response must come on a different association.
There is no Real-World activity required for the DICOM Server AE to respond to an incoming
Storage Commitment response from the remote DICOM AE.
