Objective

Stochastic tractography does not provide interactive visualization so far due to its intensive computational needs.

Approach, Plan

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.

Progress

• Cuda was integrated through PyCuda with support for numpy arrays syntax
• direct call to driver api tested
• driver kernels tested (simple matrices operations)
