2. The Problem

<Summarize the integration problem. What doesn’t work, or what needs to work.>

To extend IHE's capabilities that enable our radiology end-users to demand Enhanced MR/CT implementations, I propose implementating Cardiac Imaging and Multi-stack Spine Imaging this year and Spectroscopy next year.

  • Enhanced DICOM objects contain more and better defined attributes that increase interoperability.
  • The rate of implementation of Enhanced DICOM will strongly depend on user demands for display capabilities. Display vendors, willing to implement the support for Enhanced DICOM SOP Classes, will benefit in the selection of their basic functionality by the existence of the IHE Profiles.

3. Key Use Case

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

This is a more general purpose profile, focused on using STACK ID as a dimension index in CT and MR. In fact "spine" was just the example used in the DICOM Standard for multi-stack implementations.

It does not pose any additional display requirements other than separating the stacks to different viewing ports as already used in the PERF profile. Therefore the Spine profile could easily be redefined to be a General Purpose STACK profile.

<Feel free to add a second use case scenario demonstrating how it “should” work. Try to indicate the people/systems, the tasks they are doing, the information they need, and hopefully where the information should come from.>

4. Standards & Systems

The NEMA Taskforce for Enhanced CT/MR has already provided in 2005 test scenario's for Cardiac Imaging, Multi Stack Spine Imaging and Spectroscopy and draft specifications similar to those used to kick-start DIFF and PERF.

5. Discussion

In follow-up to the creation of the DIFF and PERF profiles it is important to keep the momentum for the creation of more clinical profiles that support the implementation of Enhanced MR and CT.

The profile would follow the pattern established by DIFF and PERF.

The SPINE profile will be a minimal editorial job, removing some requirements from the PERF profile.
