Project Description

Objective

The fiber tract dispersion computation method of Savadjiev et al. (MICCAI 2012) has recently been converted from an implementation in Matlab to C++/ITK. However, more work needs to be done in debugging and testing the C++ implementation. Currently this method is bundled with the UKF Tractography extension, but the long term goal is to make it into a stand-alone extension.

In addition, some more debugging and testing of the UKF Tractography extension is needed.

Approach, Plan

• Private git repository already exists at: git@github.com:BRAINSia/CompressedSensingDWI.git
• Debug and test the fiberTractDispersion code
• Implement needed changes to the default behaviour of UKFTractography
• Separate fiberTractDispersion from UKFTractography to create an independent Slicer extension.

Progress

• Private git repository created at: git@github.com:BRAINSia/CompressedSensingDWI.git
• Spent time debugging the vtk readers/writers for MATLAB, in order to test the MATLAB code.
• Wrote XML interfaces for the fiber tract dispersion extension, and for the compressed sensing HARDI estimation.

• Next steps: continue debugging the vtk readers/writers for MATLAB, and begin translating the algorithm implementation from MATLAB to C++.
