Key Investigators
- VT: Chris Wyatt
- BWH: Kilian Pohl
Objective
The objectives of this project are to:
- Optimize the EM Brain Classifier in Slicer on MRI images of rhesus macaques
- Develop a custom GM/WM/CSF atlas, bootstrapping from one provided by Martin Styner
- Integrate a sub-cortical atlas
- Segment data from N subjects in the alcohol naive and post-induction state.
- Compare GM/WM volume and ratios between the two states
- Compare hippocampus, putamen, and caudate volumes between states
Approach, Plan
We will use the current implementation of the EM Brain classifier in slicer. Using a manual segmentation as an estimate of ground truth in a single subject, we will optimize the EM segmenter parameters over the classification error and running time. The study will be run via VPN on a Sungrid at VT.
