Software for the fiber tracking and statistical analysis along the tracts has been implemented. The statistical methods for diffusion tensors are implemented as ITK code as part of the [[NA-MIC/Projects/Diffusion_Image_Analysis/DTI_Software_and_Algorithm_Infrastructure|DTI Software Infrastructure]] project. The methods have been validated on a repeated scan of a healthy individual. This work has been published as a conference paper (MICCAI 2005) and a journal version (MEDIA 2006). Our recent IPMI 2007 paper includes a nonparametric regression method for analyzing data along a fiber tract.

Objective

Skull Stripping is a 3D image processing technique to mask out non-brain areas in MRI images. Skull Stripping is often required before applying a segmentation technique such as the EM Segmentation. We are developing a Skull Stripping module in Slicer3 that will be able to work both on human MRIs and on monkey MRIs. This project is in collaboration with the NA-MIC project for the investigation of Alcohol Stress Interaction using monkey MRI images by Andriy Fedorov (BWH), Xiaoxing Li (VT) and Chris Wyatt (VT).

Approach, Plan

Our module, called SkullStripper, is based on the work of the NA-MIC consortium done by Snehashis Roy (JHU), Xiaodong Tao (GE) and Nicole Aucoin (BWH). First we will perform a comparison study of the Slicer3 module SkullStripper and the FSL Brain Extraction Tool (BET).
