2008 Summer Project Week:GMLongDistanceTractography

Return to Project Week Main Page

Key Investigators

• Allen Tannenbaum, John Melonakos, Georgia Tech
• Marek Kubicki, Eric Melonakos, Sylvain Bouix, BWH
• Marc Niethammer, UNC

Objective

• To experiment with the new DWI data and GM ROIs.
• To begin adapting the Finsler Tractography algorithm to handle this new data and to achieve long distance tractography between 2 GM regions.

Approach, Plan

With new data of the gray matter extent to the cingulum bundle, we will begin the process of refining the Finsler Tractography to work on these structures.

Progress

• Slicer3 Connection to MATLAB for faster processing
• Verified that the standard ODF constructions are not sharp enough for long distance
• Started investigating work by Maxime and work by Yogesh to get a sharper metric
• Made progress on the interpolation of vector fields
