Report Creator finds out what tasks have been scheduled / assigned by the Reporting Manager Worklist provided for Work Item codes e.g.: –Interpretation –Transcription –Verification RWF – Reporting Worklist Provided

General Purpose Worklist SOP Class Explicit definition of required matching and return keys for both Report Manager and Report Creator Report Creator implements at least one the following query cases: –PatientOriented Query: Worklist for a specific patient / procedure –UserOriented Query: Worklist for a particular user Report Manager Report Creator C-FIND-RQ C-FIND-RSP RWF – Reporting Worklist Provided

Report Creator takes ownership of the Work Item Report Manager updates its worklist and permits other worklist users to detect that this SPS has been claimed Report Manager Report Creator N-ACTION (GP-SPS in Progress) RWF – Work Item Claimed

Report Creator starts working on the claimed Work Item N-CREATE (GP-PPS in Progress) Report Manager Report Creator RWF – Procedure Step in Progress

Report Creator notifies Reporting Manager of PPS completion Report Creator references any created results N-CREATE (GP-PPS Completed) Report Manager Report Creator RWF – Procedure Step Completed

Report Creator notifies the Reporting Manager when it completes the scheduled Work Item and releases ownership of the Work Item Report Manager updates its worklist N-ACTION (SPS Completed) Report Manager Report Creator RWF – Work Item Completed

General Purpose Performed Procedure Step SOP Class Report Manager informs other actors of the creation and status update of the performed reporting task Allows the systems not managing the performed work to stay in sync Report Manager DSS/OF IM/IA N-CREATE (PPS in Progress) N-SET (PPS Completed) RWF – Performed Work Status Update

Improve Reporting Workflow Efficiency – Use of Worklists to Manage Reporting Tasks Eliminate Errors Associated with Paper and Film Handling Close the Information Loop - Proper Association of Reports with: –Corresponding Order –Acquired Images –Other Clinical Evidence Enable direct access to images and evidence documents to be interpreted Enable access to prior reports and old images Reporting Workflow – Value Proposition

Extension to the Scheduled Workflow to Support Typical Post-Processing Workflow Tasks: –Image Processing –Image Reconstruction –Computer Aided Detection –3D View Generation –Quality Control Ability to Schedule and Track the Status of Post- Processing Tasks Post-Processing Workflow (PPWF) – Summary
