8. 8 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, access to the radiology report across health enterprises is difficult Without XDS-I, 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 with the same mechanisms used to query other documents with the same mechanisms used to query other documents

9. 9 Value Proposition Distributed: Each Care delivery organization publishes imaging information for others. Actual images remain in the source/Image Manager. Cross-Enterprise: A Registry provides an index for published information to authorized care delivery organizations belonging to the same clinical affinity domain. Document Centric: Published clinical data is organized into clinical documents. using agreed standard document types (DICOM KOS, PDF and/or text report) Document Content Neutral: Document content is processed only by source and consumer IT systems. Standardized Registry Attributes: Queries based on meaningful attributes ensure deterministic document searches.

10. 10 XDS-I Dependencies XDS-I depends on IT Infrastructure Cross- Enterprise Document Sharing (XDS) Same Actors as in XDS Document Source Document Source Document Consumer Document Consumer Document Registry Document Registry Document Repository Document Repository Added extension to support imaging data (images and reports)

12. 12 XDS-I New Transaction requirements XDS Actors: Document Consumer Document Consumer at least one Retrieve (DICOM C-Move or WADO) at least one Retrieve (DICOM C-Move or WADO) Document Source Document Source Provide and Register Document Set Provide and Register Document Set Radiology Actors Image Manager / Image Archive Image Manager / Image Archive WADO Retrieve WADO Retrieve

13. 13 XDS-I Options Document Source must support at least one of the following options: Extensive Set of DICOM Instances Extensive Set of DICOM Instances PDF Report PDF Report Text Report Text Report Multipart Text/PDF Report Multipart Text/PDF Report

16. 16 Sharing of Extensive DICOM Instance Set The shared Document is a manifest a Key Object Selection DICOM Instance a Key Object Selection DICOM Instance Image Manager/Image Archive is required to ensure that the referenced images from within a published manifest are available to be retrieved to ensure that the referenced images from within a published manifest are available to be retrieved Document Source is responsible for replacing a previously submitted manifest Document when a change occurs to the manifest content (eg. Change of the DICOM SOP instances referenced within the manifest) for replacing a previously submitted manifest Document when a change occurs to the manifest content (eg. Change of the DICOM SOP instances referenced within the manifest)
