NA-MIC/Projects/Diffusion Image Analysis/Stochastic Fiber Tracing Applications

Objective: Recently methods and algorithms have been developed to trace white matter fibers in a stochastic matter. We want to use one of these methods on datasets with both f-MRI and Difussion weighted images. The goal is to get a probability of connection between f-MRI activated ROI's, and see if there is a difference in schizophrenic and control groups.

Progress: We have code running in matlab which was used to give prove of concept of our method, which was developed by Ola Friman. We made some improvements to his implemenation, and it is now possible to load nrrd data sets and export the paths to vtk. Currently we are processing some of our datasets, and are able to create probability maps between ROI's.
