Project Description

Objective

Implement the fiber dispersion computation method of Savadjiev et al. (MICCAI 2012) as a Slicer4 Extension. Convert the currently existing Matlab implementation into C++/ITK and test it on various datasets.

Approach, Plan

  • Create a realistic test suite based on Huntington datasets for the Matlab code.
    • [HANS - Monday] Prepare test DWI data set for preparing data
  • Create a VTK reader/writer in matlab, in order to the test the matlab code.
    • [KENT -- DONE] git@github.com:BRAINSia/CompressedSensingDWI.git
    • [PETER - DONE] Build github version of readers/writers
    • [PETER - DONE] Manually test vtk readers/writers, and convert existing test to use the binary forms


  • Convert the Matlab code to C++/ITK
    • [HANS/PETER - DONE] Create design document (i.e. this page and paer/pencil) to describe the intended inputs and outputs.
    • [PETER -- DONE] - Write desired command line interface psuedocode "caluclateDispersion --inputTract <wholebrain.vtp> --mask <roi.nrrd> --outputTract <decoratedversionofinput.vtp> "
    • [HANS/PETER -- DONE] - Create shell program in psydocode/comments with XML and cxx files with description of basic IO programming needed
    • [KENT -- Tuesday/Wednesday] -- Fill in I/O portions of psuedocode and make a compilable application that reads the inputTract, breaks it apart into necessary algorithmic components, and writes out the outputTract.
  • Create a Slicer extension
