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
