Stochastic Tractography Progress

Status

Stochastic tractography requires careful maintenance and on-going development improving its usability and performance. 

A - Development of tractography workflow 

• (a) DWI image loading

   (b) WM mask & ROIs creation
   (c) tensor estimation & visualization (this step is somewhat hidden)
   (d) tracts reconstruction & visualization (should be useful to see tracts and not only the connectivity map)  
   (e) connectivity maps creation & visualization

B - Visualization of diffusion properties - test utilities 

• (a) reveal more features related to diffusion - develop visualization

   (b) 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) 

• (a) sensitivity to inputs (WM/ROIs) if exist - needing criteria definition and algorithmic extensions

   (b) further algorythmic extensions if needed for dealing with specific reconstruction cases (tracts with multiple branches)
