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.
- would be good to be able to quickly switch among layouts for checking registration results.
Transform module specific suggestions:
- Transform module has confusing interface.
- Here, no sense of what a person is transforming (the first thing a user does is go to the module and start moving sliders, but user sees nothing move. Not intuitive to know to creaet a new transform node, apply it to a dataset, then select that transform, and apply the xlation, rotation, scale to it).
- 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.
- Choose one:
- 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.
- Choose one or more:
- if N:
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. The transform panel, like the that in the Transforms Module, needs a careful think-thru. For now this is just a placeholder to paint the picture.
