Objective
To build a lobe parcellation algorithm for our 3T data set. The spatial priors are based on 100 existing manually-lobe parcellated 1.5T 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. We will then tune the EMsegmenter of Slicer3 to perform the segmentation.
Progress
- We have been using a MATLAB(R) implementation of the atlas building algorithm to construct the atlas and fine tuning it for 10 subjects.
- Debugging matlab code
