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

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

  3. Points of Interest - NM • Appendix E, Volume 1 (Informative) • New to Nuclear Medicine? • Trouble matching NM to Scheduled Workflow? • Start Here. • 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 • Many subtleties here Radiology Participant Workshop, Oct 2004

  4. Points of Interest – Acquisition Modality • 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 Radiology Participant Workshop, Oct 2004

  5. Points of Interest –Image Manager/Archive • 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 Radiology Participant Workshop, Oct 2004

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

  7. Result Screen Export Option:Evidence Creators • Render Dynamic Result Screens • Based on the following DICOM Objects: • Multi-Frame Grayscale Byte Secondary Capture • Multi-Frame True Color Secondary Capture • Creating multiple single frame objects is NOT sufficient. • Render Static Result Screens • Using single frame DICOM Secondary Captures is sufficient • Using Multi-frame to render single or several related static result screens is recommended • provides better image comment/label attributes • provides implicit display order • displayed by stepping, not cine • Must generate appropriate Secondary Capture objects from any Result Screens created.

  8. Example Result Screen Radiology Participant Workshop, Oct 2004

  9. Points of Interest – Image Display • Image Display • Retrieve Images [16] • Display NM and Result-Screen 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 Radiology 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 new local color tables to system • Change intensity of grayscale result screens (recommended) • Display Series Description tag • …, etc. Radiology Participant Workshop, Oct 2004

  11. 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” Radiology Participant Workshop, Oct 2004

  12. Display Formats • Grid display • Frames from one image set • Comparison display • Compare frames from multiple image sets • Fit display • Frames from multiple image sets Radiology Participant Workshop, Oct 2004

  13. Review Option: Image Displays • Adds Image Display requirements to support Review of NM Images • MPR Display • More series at once • Different series types together • Pixel value display • More reason to review Appendix E in detail Radiology Participant Workshop, Oct 2004
