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'

Below is a sketch to follow up an idea Steve Pieper had for guiding a user through available registration options. It shows a Registration helper module that re-presents functionality from other modules:
