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 (http://www.na-mic.org/Wiki/index.php/DBP2:UNC).


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