  Projects List

• 

  Segmentation of Vervet Subcortical Structures

Key Investigators

• VT: Chris Wyatt, Vidya Rajagopalan
• BWH: Andrey Fedorov, Ron Kikinis, Nicolas Rannou, Sylvain Jaume

Objective

• To improve cortical segmentation of Vervet segmentation Results
• Use Change tracker module in Slicer to study hippocampal changes between subjects at two time points

Approach, Plan

• Improve rigid registration results by optimizing parameters
• Add bias correction to workflow to improve segmentation results
• Study hippocampal changes between subjects at two time points using Change Tracker

Progress

• ChangeTracker augmented with the capability to accept externally-defined segmentation (ChangeTrackerVT in NAMIC Sandbox)
• MRIBiasCorrection module by Nicolas Rannou available in NAMIC SandBox, initial testing on rhesus data done
• GWE set up on SPL Cluster for registration parameter exploration
