SMART Imaging Access
0.1.0 - ci-build
SMART Imaging Access, published by Argonaut Project. This guide is not an authorized publication; it is the continuous build for version 0.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/argonautproject/smart-imaging/ and changes regularly. See the Directory of published versions
| Official URL: http://fhir.org/argonaut/smart-imaging/StructureDefinition/smart-wado-endpoint | Version: 0.1.0 | |||
| Draft as of 2026-08-21 | Computable Name: SmartWadoEndpoint | |||
A DICOM WADO-RS endpoint referenced from a SMART ImagingStudy.
The address is a WADO-RS base URL: the app appends
/studies/{Study Instance UID} (and optionally deeper paths) to retrieve
DICOM data. The requires-access-token extension says whether the app
presents its SMART access token on those requests.
Usages:
You can also check for usages in the FHIR IG Statistics
