Text of DICOM GPWL: Post-Processing Workflow, Reporting Workflow

  • 1. Post Processing Workflow Reporting Workflow IHE Workshop 2006 IHE Radiology Education Sanjay Jain, Planning Committee

2. Post-processing Workflow

  • Abstract
  • Actors
  • Transactions
  • Grouping
  • Worklist Queries

3. Abstract / Scope

  • Schedule, distribute and track post-processing workflow steps using standardized mechanisms
    • Manage worklists, Query Worklists
    • Track status
    • Perform & notify image processing & CAD steps
    • Workitems can be performed and the resulting status known and shared

4. Value Proposition

  • Schedule, distribute and track the status of typical post-processing workflow steps such as:
    • Computer-Aided Detection
    • Clinical Analysis Image Processing
    • 3-D view generation
    • Quality Assurance

5. Post Processing Manager

  • Only one actor introduced in this profile
  • Must be grouped with either DSS/Order Filler or Image Manager

6. Post-Processing Manager

  • Grouped with Image Manager

Transactions

  • Transaction s based on following DICOM Services :
    • General Purpose Worklist
    • General Purpose Scheduled Procedure Step
    • General Purpose Performed Procedure Step
  • Storage Service Classes
    • Basic Text SR SOP Class
    • Enhanced SR SOP Class
    • Comprehensive SR SOP Class

Patient Oriented worklist Query

  • Worklist for a specific patient/procedure
  • SCU shall support all combinations of the matching keys

  • Transactions
  • Grouping

16. Diagnostic Reporting Use Cases

  • Predefined report
  • Workitem deferred
  • Direct report creation
  • Interpretation and dictation
  • Transcription
  • Partial completion
  • Verification

17. Predefined report

  • The user chooses a report from a list of pre-configured draft reports

The results are normal I will also verify the report 18. Task deferred

  • The user selects the task and decides not to perform it

Put this task back on the worklist. 19. Partial Completion

  • The user begins the task and then decides that this task cannot be completed at this moment

Bad data quality! New acquisition is required 20. Verification

  • The user may need to correct the report's content by dictation

Send report back to the transcriptionist for correction 21. Abstract / Scope

  • Workflow Profile addresses the need to schedule, distribute and track the status of the reporting workflow tasks such as
    • Interpretation
    • Transcription
    • Verification
  • Worklists for each of these tasks are generated and can be queried
  • Report format neutral (DICOM SR, HL7/CDA, XML, PDF, etc.)

22. Reporting Workflow Actors

  • Report Manager
  • Report Creator
  • Report Reader
  • Department System Scheduler/Order Filler
  • PPS Manager
  • Image Manager/Image Archive
