  1. Sharing Images without CDs, The Next Imaging Sea Change GE Healthcare • Chris Lindop • GE Healthcare • Interoperability & Standards

  2. In the Beginning:Film

  3. In the beginning…. open image exchange started with one reliable method: FILM Advantage: Everyone can view the Film Issue: to be solved: Inconsistent visual quality Annotations, notes, etc. were attached “stuck-on” IHE Solution: Consistent Presentation of Images (CPI) Integration Profile Grayscale Standard Display Function (consistent images) Grayscale Softcopy Presentation State (Annotations) Film – the First Standard for Image Exchange

  4. Radiology Enters the Digital Image Exchange:Portable Media: CDs

  5. CDs or coasters? Then came the introduction of CDs and other portable media, but for most, was simply coasters for your morning coffee. Issues to be solve: Media in-compatibility Inconsistent viewer capabilities No import method to reviewer’s view station IHE Solution: Portable Data for Imaging (PDI) – Standard media format Basic Image Review (BIR) – Basic Viewer capability requirements Import Reconciliation Workflow (IRWF) – Standard import method Portable Media– the next interop challenge

  6. Electronic Images Sharing beyond your Institution The Image Exchange

  7. Use of a shared XDS Community-based infrastructure to access Radiology Reports and Images (XDS-I) • Between Radiology and : • Imaging specialists • Non-imaging clinicians • Patients Hospital PACS Y Radiology -to-Radiology Radiology –to – Physicians PACS Z Imaging Center Physician Practice Specifies how Radiology Information Objects, Both DICOM Instances and non-DICOM Reports are distributed in an eHealth Community 7

  8. XDS Affinity Domain Considerations Set of organizations/systems organized around a single Registry Common set of Codes Single Patient ID Domain Involves business and legal agreements Security model/agreements

  9.

  14. Electronic Images Sharing beyond ….. Cross-Community Image Exchange

  15. Cross-Community Access of Images (XCA-I) the next Sea change Foundational with Standards incl. DICOM Web services • DICOM WADO-WS supp-148) Interoperable with clinical portals • Compatible with IHE Web services profiles, including Security and privacy Interoperable with PACs and vendor neutral archives • Ready for cloud hosted apps

  16. Why extend XDS? • XDS only addresses document sharing within an XDS Affinity Domain • Cross-Community addresses the questions: • How to share documents between XDS Affinity Domains? • How to share documents with non-XDS Affinity Domains?

  19. XCA-I Transaction Diagram

  20. XCA-I Foundational with Standards incl. DICOM Webservices DICOM WADO-WS supp-148) Interoperable with clinical portals Compatible with XDS.b, XUA, ATNA Interoperable with PACs and vendor neutral archives Compatible with XDS-I.b, DICOM-WS Ready for cloud hosted apps

  21. Imaging Object Change Management (IOCM) IOCM specifies how to communicate changes applied on existing imaging objects to other systems. Changes include • rejection due to quality or patient safety reasons, • correction of incorrect modality worklist entry selection, • expiration due to data retention requirements. IOCM is fully compatible with existing profiles!
