5. Manual Registration

Need a helper or guide to promote best practices...

  • Best practices: when and how to apply deformations?
  • and When to resample?


Suggestions for general common tools:

  • choose a "reference" dataset
  • Add a target dataset
  • Choose to inherit another dataset's transform or start fresh
  • would be good to be able to easily toggle colormap from color to grey and back.



Transform module specific suggestions:

  • Transform module has confusing interface.
  • Here, no sense of what a person is transforming.
  • Would be good to slide translation or rotation scale by either course or fine increments

6. Automatic Registration

Lots of registration methods but hard for a user to know which one to use and when. Suggestion: helper questions could guide the process -- this is rough, can we find a valid decision tree?:

  • Are target and reference the same case? Y/N
    • if N:
      • Choose one:
        • A. Is reference an atlas?
        • B. a different patient?
        • C. same patient but different modality?
        • D. same patient but different date?
        • E. same patient, different modality and different date?
          • Based on selection, recommend an Automatic registration method, or a set of them to try.
    • if Y:
      • Choose one or more:
        • a different modality?
        • a different date?
        • a different modality and date?
          • Based on selection, recommend an Automatic registration method, or a set of them to try.

idea: flexible registration 'guide'

These are sketches to follow up an idea Steve Pieper had for guiding a user through available registration options. First is a Registration helper module that re-presents functionality from other modules:

Then is a sketch of a tool that would pop up and move stepwise thru a set of registration sub-tasks, making recommendations along the way. A guide handles navigating through the application GUI so that a user can also learn where functionality is as they are guided.
