Stochastic Tractography Progress

Status

Stochastic tractography requires careful maintenance and on-going development improving its usability and performance. 
A - Development of tractography workflow 
  • DWI image loading
  • WM mask & ROIs creation
  • tensor estimation & visualization (this step is somewhat hidden)
  • tracts reconstruction & visualization (should be useful to see tracts and not only the connectivity map)
  • connectivity maps creation & visualization
B - Visualization of diffusion properties - test utilities 
  • reveal more features related to diffusion - develop visualization
  • finalize batch - testing different parameters of the stochastic tractography with different datasets - wrap up of the results
C – Study of limit cases (tract reconstruction issue) 
  • sensitivity to inputs (WM/ROIs) if exist - needing criteria definition and algorithmic extensions
  • further algorythmic extensions if needed for dealing with specific reconstruction cases (tracts with multiple branches)


Updates/Progress

A - Development of tractography workflow 
B - Visualization of diffusion properties 
C – Study of limit cases (tract reconstruction issue)
