Rationale for Change: There are at least 3 places where DICOM usage conventions are documented in IHE:
1. In the IHE Supplement Template, Rev 10.6, 2022-01-17, Section 7.1, Table 7.1.2-1 and 7.1.2-2
2. IHE General Introduction, Appendix E, Section E.2
3. IHE RAD TF-2: 2.2.
The contents of these sections are not aligned.
Some issues: ·
- Appendix E.2 only contains query conventions; it does not contain usage conventions for content definitions (but does not refer to ‘storage’) ·
- The supplement template refers to Appendix E.2, and then adds usage conventions for content (but does not clearly distinguish between the two). ·
- The RAD TF contains conventions for query and storage (i.e. content).
- The content/storage conventions in RAD TF-2 and the supplement template are not identical. The query conventions are close in both documents (but the supplement template does not define R+* explicitly.
This is a problem. I have recently witnessed a new editor using the supplement template whose content is probably the most confusing (as it does not clearly distinguish between query and content/storage.
I recommend moving the RAD definitions into Appendix E, reviewing/updating that to ensure it’s clear and complete, and then updating references to point to the one source of truth for DICOM conventions. (Note that updating references is not a minor task. In the RAD TF, there are lots of references to RAD TF-2:2.2…. we could update RAD TF-2: 2.2 to point to E.2 rather than trying to find/replace all internal reference).
