Projects/Diffusion/2007 Project Week DTI Population Analysis

Key Investigators

• UNC: Casey Goodlett, Guido Gerig
• Harvard: Marek Kubicki

Objective

We are developing methods for building atlases of DTI data to provide a reference coordinate system for statistical analysis.

Approach, Plan

Our approach for building a DTI atlas is based on non-rigid registration of tensor images using a shape measure for the tensor images to drive the registration process. Our goal is to separate the shape variability from the diffusion variability through the registration process.

Plan: Our goal for the project week is to perform statistical analysis on the data provided by the PNL, which has already been registered using the procedure described in the links below.
