Data quality, NAMIC DTI pipeline
- Issues?
ROI definitions and impact on different methods
- Force all methods to use the same ROIs?
- For streamline methods larger ROIs than the tract itself good
Methods:
- Streamline Slicer2 (Sonia)
- Streamline Fiberviewer (Casey)
- Stochastic Slicer3 (Tri)
- Shortest path, volumetric (John)
- Shortest path, volumetri (Tom)
Review and define metrics to compare results, which methods to compare?
Current metrics: tensor invariants (FA, trace, mode, norm), volume, length.
- 12 different tracts
- Tracts voxelized -> volumetric result from tracts
- Missing parts of a tract, how should be penalized?
- Statistics along the tracts, should we sum along the tract to get one measure?
- Distributions across the tract
- Atlas (Casey)
