<h3>Objective</h3>
Stochastic tractography does not provide interactive visualization so far due to its intensive computational needs.

<h3>Approach, Plan</h3>
Idea would be to visualize online paths generated in a point of interest like a fiducial. This approach would be based on the online visualization of streamline tractography done by moving a fiducial interactively. 

During the summer week, we will continue our work to develop a concrete solution in investigating acceleration means based mainly on CUDA.

<h3>Progress</h3>
* Cuda was integrated through PyCuda with support for numpy arrays syntax
* direct call to driver api tested
* driver kernels tested (simple matrices operations)
