Minutes
- Questions for IT Infra for performance of retrieve of large binary objects (image sets)
- Image studies are treated differently than other document sets in that they are not submitted to a repository; a Key Object Selection document is submitted
- Rad Tech has redrafted XDS.b to use the MTOM/XOP retrieve transactions for image sets
- One uid per image
- Questions for WG27 about security of WADO transactions: WG27 does not intend to address security of WADO, but to define Web Services transactions to replace it
- WADO retrieve uses a simpler transaction than the Web Services MTOM/XOP retrieve defined in XDS.b; is it possible to have a secure retrieve that allows for transformation of the data payload to jpg (as in WADO)?
- XCA: defines method for sharing across "communities" (affinity domains or other); requires that you need patient ID at site
- XCA can retrieve document set with transaction identical to the one in XDS.b
- XCA requires Home Community ID (which should already be provided in manifest)
- Focus on risk analysis: Is it necessary to authenticate individuals across sites? Is a request from a trusted node sufficient?
- Discovery of repositories
- Done via configuration (rather than as a Web service)
- Query and Retrieve Transactions
- Need capability to filter returns on patient, study type, date, etc
- Domain needs to organize its information in a particular way
- Is it possible to use Document Set as a proxy for Study (or series)
- XDS Queries can be limited by format code/type: manifest as a document type that should show up in query responses
