B.42 Bi-directional Proxies For Managing A Modality Performed Procedure Step

The DICOMweb Modality Performed Procedure Step Service may be deployed in a hybrid environment, i.e., an environment in which both DICOMweb and DIMSE are used. In such a hybrid environment, a proxy can broker Transactions from one service to the other, allowing a DICOMweb origin server or a DIMSE SCP to support workflow primitives for a mixed set of DICOMweb user agents and DIMSE SCUs.

DICOM does not require an implementation of proxies; however, since they would be very useful in a hybrid environment, the examples in this section show how this could be done.

Figure B.42.1-1 shows how a proxy could facilitate a request for creating a modality performed procedure step from a DIMSE SCU to a DICOMweb origin server.

Figure B.42.1-2 shows how a proxy could facilitate a request for creating a modality performed procedure step from a DICOMweb user agent to a DIMSE SCP.
