Project Description

Objective

  • Develop a modified distance for measuring the similarity between fiber tracts to improve the performance of clustering fiber tracts, especially to distinct corpus callosum and mistakenly tracked cingulum bundle.

Approach, Plan

Progress

  • We've developed and implemented a modified mean distance to incorporate with shape similarity between fiber tracts. The shape similarity model is based on the angle shift among the vectors to direct corresponding sample points along fiber tracts. The modified mean distance can address the challenge of distincting corpus callosum and mistakenly tracked cingulum bundle. The outputs have a relatively smaller intra-Hausdorff-distance of clustered tracts than the outputs from mean distance.
