2008 Winter Project Week:StochasticTract Arcuate

Return to 2008_Winter_Project_Week

Volume rendering of the connectivity map generated using the Stochastic Tractography Filter. Seed region was the inferior frontal gyrus and end region was the temporal lobe (ROIs are shown as wireframes)

Objective

The objective of this project is to use the Stochastic Tractography Filter in Slicer3 in a group comparison of the arcuate fasciculus between healthy controls and chronic schizophrenics.

Approach, Plan

The Stochastic Tractography Filter has been integrated into Slicer3. Our approach is to use ROIs automatically generated from the Freesurfer reconstruction to generate connectivity maps of the arcuate fasciculus in matched groups of healthy controls and chronic schizophrenic patients. We will investigate how best to measure the diffusion properties of the tracts generated by this filter and how to facilitate a group comparison.
