2008 Summer Project Week:AtlasFreeSegmentation

Key Investigators

• MIT: Tammy Riklin-Raviv, Polina Golland

 UNC: Clement Vachet, Martin Styner 

Objective

Our objective is the simultaneous segmentation of N aligned MR images where the regions of interest are corresponding anatomical (brain) structures across N subjects. We assume that a probability atlas is not available.

Approach, Plan

In the project week we plan to test the algorithm developed for atlas free segmentation on the UNC Pediatric (Autism) MRI data.

Progress

We have implemented the algorithm and tested it on MRI images of 50 subjects.
