2010 Winter Project Week HARDI CONNECTIVITY

  Projects List

Key Investigators

• UNC-Chapel Hill: Yundi(Wendy) Shi, Deepika Mahalingam, Martin Styner

Objective

We are developing methods to study the connectivity of neonatal brain data. The goal is to 1) perform probabilistic-based tractography using HARDI information; 2) visualization of ODF along with fiber tracking results in Slicer and 3) employ all the information in connectivity analysis mainly in the neonatal data.

Approach, Plan

• Compare and select the most appropriate HARDI technique for the neonatal data
• Fiber tratography and connectivity information analysis using HARDi information
• Visualization ( implementation of a module in Slicer3)

Progress

We have the matlab implementation of various QBall techniques and have applied those techniques to neonatal human data and primate data. We're also learning to use the CAMINO package and looking for ways to expand the functions in visualization and fiber tratography.
