Objective
We have developed techniques for finding the optimal geodesic paths between two regions of interest in DWMRI data.
The objective of this project is to port the Fast Sweeping and optimal geodesic path tractography code to ITK.
Approaches and Challenges
Our approach is described by the references below. Our challenge is to build the ITK infrastructure (such as new ITK iterators) to support this algorithm.
Progress
June 2007 Project Week
This is where you put in progress made in Project Week 2007.
Jan 2007 Project Half Week
We finished the itkDirectionalIterator which will be needed in the Fast Sweeping implementation. Furthermore, we made progress in porting our Matlab code to ITK.
