White Matter Laterality/Asymmetry Measurement
Key Investigators
- Harvard Medical School: Lauren O'Donnell
- Kitware: JC (Thanks for help on how to integrate as a Slicer4 module/extension)
- Harvard Medical School: Sandy Wells (Thanks for helpful discussions on angle representation and objective functions for registration)
Objective
- Fast computation of white matter
- fiber tract laterality indices
- in python and ... Slicer4
Approach, Plan
- So far have preliminary code running in python/vtk
- Slicer-ification is goal for this week
- Another goal: learn how to make an extension module
- Another goal: can this module use testing framework
Progress
- Project is now organized as a python package
- Command line script written to run on large groups
- Initial testing on R/L handedness group data showed significant differences
- Preprocessing and midsagittal alignment have been implemented
