FHIR/DICOMweb use cases and boundaries

At the HL7 WGM in Orlando, there was discussion about the boundary between FHIR and DICOMweb, and whether the FHIR resources are at the right level of detail for the intended use cases.

Review the discussion and any progress.

Additional build warnings

Several build warnings don’t offer a straight-forward solution. Determine if we intend to file a tracker item to change the resource or request suppression of the warning. My email to the workgroups, and Grahame’s response, can be found in the listserv archives. The warnings include:

• Missing entered-in-error status
• Cannot search on ImagingStudy url elements
• ImagingObjectSelect missing identifier element; ImagingStudy identifier not searchable.

ONC standards advisory

HL7 has requested that working groups collect feedback on changes to the 2016 ONC Standards Advisory for in preparation for the 2017 Advisory. To date we have received one submission (attached). We will review the submission, and any other comments, to prepare WG feedback to HL7.

Proposed ImagingObjectSelection and ImagingStudy updates in response to MHD-I

II WG/WG-20 discussed IHE MHD-I in Orlando. IHE RAD TC met last week and modified the proposal to allow multiple retrieval URLs in ImagingObjectSelection.

Discussion of how to encode that:

• Replace url with wadoRsUrl, and wadoUriUrl
• Replace url (0..1) with Attachment (0..*) and with some means (extension?) of indicating which url is which
• ...?

Review outstanding tracker status
