  1. Nuclear Medicine Image (NM)Integration Profile Kevin O’Donnell IHE Radiology Technical Committee Member, Toshiba Medical Systems Company Participant Workshop, Oct 2004

  2. NM – Actors and Transactions Participant Workshop, Oct 2004

  3. Points of Interest • Appendix E, Volume 1 (Informative) • New to Nuclear Medicine? • Trouble matching NM to Scheduled Workflow? • E.2 NM Workflow – What happens in NM procedures • E.3 NM Worklists – How to schedule/model it • E.4 NM Data – What to expect in the DICOM • E.5 NM Display – How it should be presented • Lots of subtleties Participant Workshop, Oct 2004

  4. Points of Interest • Acquisition Modality • Modality Images Stored [8] • Create NM objects as specified • additional attribute & vector handling • e.g. Cardiac context codes, slice spacing, patient orientation • Study & Series UID creation clarification • e.g. After PPS complete, new images MUST be new series • e.g. Reconstructed images MUST be new series Participant Workshop, Oct 2004

  5. Points of Interest • Image Manager/Archive • Store/Retrieve NM Objects • Store/Retrieve Secondary Capture Objects • Refer to list in the spec. • “Level 2” storage requirement clarification • e.g. keep private tags • Support for Series Description as Query matching/return key Participant Workshop, Oct 2004

  6. Points of Interest • Evidence Creator • Creator Images Stored [18] • Ditto. (See Acquisition Modality) • Result Screen Export Option Participant Workshop, Oct 2004

  7. Result Screen Export Option:Evidence Creators • Render Static and Dynamic Result Screens • Based on the following DICOM Objects: • Secondary Capture • Multi-Frame Grayscale Byte Secondary Capture • Multi-Frame True Color Secondary Capture • Generate appropriate Secondary Capture objects from any Result Screens created. Participant Workshop, Oct 2004

  8. Example Result Screen Participant Workshop, Oct 2004

  9. Points of Interest – Image Display • Image Display • Retrieve Images [16] • Display NM and Secondary Capture Images • Note requirement for Color, Greyscale, Static & Dynamic Secondary Capture • Support specified NM essential display capabilities • Additional attribute handling • e.g. Patient State, Image Orientation, Detector Sequence, View Code Sequence • Review Option Participant Workshop, Oct 2004

  10. Points of Interest – Image Display • Handle multi-frame / multi-vector images • Multiple simultaneous cines • Grayscale and color result screens • Dynamic and static result screens • Original resolution and scaled • Separate adjustment of upper and lower window levels • Apply local color tables to grayscale screens • Add color tables to system • Change intensity of grayscale result screens • (strongly recommended) • Display Series Description tag Participant Workshop, Oct 2004

  11. Points of Interest – Image Display • Scale “intelligently” to avoid presenting postage-stamp size NM images • Just because it was acquired at 64x64 doesn’t mean they want to review it at 64x64 Participant Workshop, Oct 2004

  12. Points of Interest – Image Display • Scale “intelligently” to avoid presenting postage-stamp size NM images • Allow user to select different vectors/framesets of complex multi-frame images • Allow user to separately adjust intensity for different framesets (eg, phases) in the same “image” Participant Workshop, Oct 2004

  13. Review Option <More details> Adds requirements to the Image Display to allow Review of NM Images • Image Displays • Must additionally support MPR Display, more series, selected different series types together, etc. Participant Workshop, Oct 2004

  14. Display Formats • Grid display • One image set • Fit display • Multiple image sets • Comparison display • Multiple image sets Participant Workshop, Oct 2004

  15. More information…. • IHE Web sites: http://www.rsna.org/IHE • Technical Frameworks: • RAD V5.5 • Technical Framework Supplements - Trial Implementation • May 2004: Radiology Participant Workshop, Oct 2004
