1. Proposed Workitem: Presentation of Processed Images Profile

Proposal Editor: Michael Planchart (GE?)
Editor: <Name of candidate Lead Editor for the Profile, if known>
Domain: Radiology and Cardiology

2. The Problem

Systems produce a variety of Processed images:

Computer Aided Detection (CAD) results
Soft tissue or bone subtraction images
Residual or Temporal Subtraction images

These images (especially CAD) may have Region of Interest (ROI) coordinates provided as series 6000 overlay tags, GSPS annotations, or SR data.

However,

Some hospitals do not want to store them in PACS, claiming liability issues or limited resources (e.g. memory, bandwidth, etc.),
Some PACS viewers can't display the Regions of Interest (ROI) either by toggling on/off series 6000 overlay tags or by using the coordinates contained in the SR
Some PACS viewers can't do "hanging protocols" unobtrusively in the workflow

3. Key Use Case

<Describe a short use case scenario from the user perspective. The use case should demonstrate the integration/workflow problem.>

Images should be consumed and displayed by PACS viewing workstations in a way that compliments the viewing experience and workflow of the radiologist.

4. Standards & Systems

<List existing systems that are/could be involved in the problem/solution.>

<If known, list standards which might be relevant to the solution>

5. Discussion

<Include additional discussion or consider a few details which might be useful for the detailed proposal>

<Why IHE would be a good venue to solve the problem and what you think IHE should do to solve it.>

<What might the IHE technical approach be? Existing Actors? New Transactions? Additional Profiles?>

<What are some of the risks or open issues to be addressed?>

IHE should ...

+Systems produce a variety of Processed images:
-The challenge is having the 2-dimensional processed images (e.g. Computer Aided Detection (CAD) results, Soft tissue or bone subtraction images, Residual or Temporal Subtraction images, etc.), to be consumed and displayed by the various PACS viewing workstations in a way that compliments the viewing experience and workflow of the radiologist.
+:* Computer Aided Detection (CAD) results
+:* Soft tissue or bone subtraction images
+:* Residual or Temporal Subtraction images
-It is very important that the processed images should not be a cause of disruption of their workflow nor be obtrusive to their viewing experience.
+These images (especially CAD) may have Region of Interest (ROI) coordinates provided as series 6000 overlay tags, GSPS annotations, or SR data.
-In the case of CAD results processed images may be provided with series 6000 overlay tags populated, GSPS, or optionally produce a DICOM Structured Report (SR) that contains the coordinates of the Regions of Interest(ROI) for the CAD results.
+However,
+:* Some hospitals do not want to store them in PACS, claiming liability issues or limited resources (e.g. memory, bandwidth, etc.),
+:* Some PACS viewers can't display the Regions of Interest (ROI) either by toggling on/off series 6000 overlay tags or by using the coordinates contained in the SR

-Today, there are a myriad of obstacles each representing an individual use case and the most common are:
