Web-based Image Access (WIA) provide methods for image sharing and �interactive viewing of imaging studies �using RESTful services regardless of the backend image management infrastructure.
Summary
The Web-based Image Access (WIA) Profile provide methods for image sharing and �interactive viewing of imaging studies �using RESTful services such as �WADO-RS and QIDO-RS.
Benefits
- Provides a mechanism to query/retrieve DICOM imaging objects using DICOM RESTful API (QIDO-RS and WADO-RS) with JSON/XML representation of the object header (JSON in PS 3.18 and XML in 3.19) rather than traditional binary format
- Ease the adoption of non-traditional DICOM devices (e.g. mobile devices) to query/retrieve imaging objects from existing image sharing infrastructure (PACS, VNA, etc.)
- Enable interactive viewing for imaging studies on XDS-I
- Ease the access to imaging documents when integrating with ITI MHD
- Easy to work across firewalls using HTTP(S) compared to DICOM
- Easy to support authentication and encryption using HTTPS compared to DICOM without dependent on an existing secure network (VPN between sites)
Use Cases
- Image Sharing
- Interactive Viewing of Studies
Key highlights
- Neutral about backend image sharing infrastructure
- XDS/ XDS-I
- DICOM / DICOMweb
- Integrates with ITI MHD
- Document Consumer can locate and interact with imaging studies more efficiently using document metadata instead of manifest
Systems Affected
- Imaging Document Consumer (e.g. mobile tablet, medical camera, etc.) that queries or retrieve imaging objects
- Imaging Document Source (e.g. PACS, VNA, proxy) that responses to consumer imaging objects retrieval requests
- Imaging Document Responder (e.g. PACS, VNA, proxy) that responses to consumer imaging objects query requests
