Objective

To build an atlas based on 100 existing manually-lobe parcellated 1.5T data to aid in automatic lobe parcellation of 3T data.

Approach, Plan

Our plan is to use an algorithm described in Reference 1 to construct probability maps of the lobes using an unbiased registration approach. The algorithm uses a label space representation that allows for direct registration.

Progress

We are using a MATLAB(R) implementation of the algorithm to construct the atlas and fine tuning it for 10 subjects.
