Nuclear Medicine Image Profile: Kevin O'Donnell

  1. 1. Sept 13-15, 2004 IHE Interoperability Workshop1 Integrating the Healthcare EnterpriseIntegrating the Healthcare Enterprise Nuclear Medicine Image - NM Dr. Jerry Wallis (SNM) IHE Radiology Technical Cmte Kevin O’Donnell (Toshiba Corp.) Co-Chair, IHE Radiology Planning Cmte
  2. 2. Sept 13-15, 2004 IHE Interoperability Wo2 Nuclear Medicine Image - NMNuclear Medicine Image - NM Patient Info. Recon- ciliation Access to Radiology Information Consistent Present- ation of Images Basic Security - Evidence Docs Key Image Notes Simple Image & Numeric Reports Presentation of Grouped Procedures Post- Processing Workflow Reporting Workflow Charge Posting Scheduled Workflow Portable Data for Imaging NM Image NM Image
  3. 3. Sept 13-15, 2004 IHE Interoperability Wo3 NM Image – The ProblemNM Image – The Problem DICOM NM objects are different and support in products is inconsistent NM clinical display practices are different and support in products is inconsistent Clinical Analysis Programs are used extensively (particularly for Cardiology), but no support for distribution and display of those Result Screens NM Users are not adept at getting these requirements accurately included in RFPs Vendors (especially of general purpose systems) are not adept at accurately representing their support for such features
  4. 4. Sept 13-15, 2004 IHE Interoperability Wo4 NM Image FormatNM Image Format Understood by dedicated NM systems Often Misunderstood by general storage and display systems Multiframe  Dynamic  Anterior  Posterior  Multi-energy NM Image Image vectors

  7. 7. Sept 13-15, 2004 IHE Interoperability Wo7 NM ImageNM Image Click and move mouse down to adjust window level, right to adjust window center
  8. 8. Sept 13-15, 2004 IHE Interoperability Wo8 NM – The SolutionNM – The Solution New Profile  for Users to request and Vendors to claim No New Actors or Transactions  Additional requirements on existing actors and transactions  Two New Options New Informative Text in Vol. 1  Clarifications of NM Workflow mapping to SWF  Explanation of NM Data  Explanations of NM Clinical Display concepts New Normative Text in Vol. 2  <See Following Slides> Connectathon to help test and confirm

  10. 10. Sept 13-15, 2004 IHE Interoperability Wo10 NM Image ProfileNM Image Profile Acquisition Modalities (Modality Images Stored [8])  Create NM objects as specified (additional attribute & vector handling)  Include specific codes in Cardiac studies Evidence Creators (Creator Images Stored [18])  Create NM objects as specified (additional attribute & vector handling)  Include specific codes in Cardiac studies Image Manager/Archives  Store/Retrieve NM & Secondary Capture (SC & MFSC) Objects Image Displays (Retrieve Images [16])  Display NM and Secondary Capture (SC & MFSC) Images  Support specified display capabilities
  11. 11. Sept 13-15, 2004 IHE Interoperability Wo11 Result Screen Export OptionResult Screen Export Option Provides storage, retrieval and display of 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 Evidence Creators  Generate appropriate Secondary Capture objects from any Result Screens created.
  12. 12. Sept 13-15, 2004 IHE Interoperability Wo12 Review OptionReview Option Adds requirements to the Image Display to allow Review of NM Images Image Displays  Must additionally support MPR Display, more frames, different series types together, etc.
  13. 13. Sept 13-15, 2004 IHE Interoperability Wo13 PACSPACS →→ NM Workstation ?NM Workstation ? No !  No filtering  No ROI  No TAC  No renal, lung … processing  No reframing  No cardiac processing
  14. 14. Sept 13-15, 2004 IHE Interoperability Wo14 Image DisplayImage Display Support separate adjustment of upper and lower window levels Show multiple cines Display grayscale and color result screens Display dynamic result screens Apply local color tables to grayscale screens Add color tables to system Change intensity of grayscale result screens  (strongly recommended)
  15. 15. Sept 13-15, 2004 IHE Interoperability Wo15 Image DisplayImage Display Must use “intelligent” scaling 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
  16. 16. Sept 13-15, 2004 IHE Interoperability Wo16 Image DisplayImage Display Must use “intelligent” scaling to avoid presenting postage-stamp size NM images Must allow the user to select different vectors/framesets of complex multi-frame images Must allow the user to separately adjust intensity for different framesets (eg, phases) in the same “image”
