  Projects List

Key Investigators

• UNC-Chapel Hill: Garrett Larson, Martin Styner, Ipek Oguz
• Core 2 support: TBD at project week, Luis Ibanez

Objective

I am developing tools to measure and visualize deformation fields and tensors (with application to rodent brains). The goal is to produce a Log Euclidean map ITK filter and Slicer plugin for open source distribution.

Approach, Plan

• Develop Log Euclidean deformation field filter
• Develop external module for use in Slicer computing deformation tensor field and its logEuclidean map

Progress

• Produced ITK filter to create deformation tensor image from deformation field
• Produced ITK filter to create log-Euclidean geodesic anisotropy image from deformation tensor image
