3. www.ihe.net XDS-I.b Abstract / Scope Sharing of Imaging Information across affiliated health enterprises Imaging Information includes  extensive sets of DICOM instances including images, evidence documents and presentation states  diagnostic reports provided in a "for display" form  selection of diagnostically significant images associated with the report content

4. www.ihe.net XDS-I.b Value proposition Imaging component of the Electronic Health Record: Shared imaging Record, in a community, region, etc. Effective means to contribute and access imaging documents across health enterprises.  Without XDS-I.b, access to the radiology report across health enterprises is difficult Scalable sharing of imaging documents between radiology departments, private physicians, clinics, long term care, acute care with different clinical IT systems. Easy access: Care providers are offered means to query and retrieve imaging documents (images and reports) of interest  using the same mechanisms used to query other documents

10. www.ihe.net XDS-I.b Actors and Transactions

11. www.ihe.net What’s New in XDS-I.b New Provide and Register Imaging Document Set Transaction  Updated to use MTOM/XOP Transport mechanisms  Fully compatible with existing XDS.b Repositories and Registries  More heavily leverages XDS-SD for CDA-wrapped text reports New Retrieve Imaging Document Set Transaction  Web services based retrieval of DICOM images  Based on XDS Retrieve Document Set Transaction Key Actor Requirements  Imaging Document Source is required to support all retrieval types; Imaging Document Consumer can choose “Old” version of XDS-I is simultaneously deprecated  No more “SOAP with attachments” based Provide transaction

12. www.ihe.net XDS-I.b Dependencies XDS-I.b depends on IT Infrastructure Cross-Enterprise Document Sharing (XDS) Profiled XDS metadata with radiology specifics  Acquisition Modality (e.g. CT, MR)  Anatomic Region (e.g. Arm, Elbow, Hand)  Requested procedure (e.g. MRI Knee with contrast) Reuses CDA-wrapper defined by XDS-SD for plain text reports. XDS-I.b specific Actors  Imaging Document Source  Imaging Document Consumer (must be grouped with XDS Document Consumer) XDS Actors reused  Document Consumer, Document Registry, Document Repository

13. www.ihe.net Implementation Considerations XDS-I.b security considerations  XDS-I.b actors must be grouped with ATNA Secure Node or Secure Application Actor  Document retrievals must be capable of being done across a protected (encrypted) channel. Implementation Resources (XML schemas and WSDL)  Will soon be available via link at http://wiki.ihe.net/http://wiki.ihe.net/
