Objective
We have developed techniques for finding the optimal geodesic path (or anchor tract) between two regions of interest in DWMRI data.
The objectives of this project are to port the Fast Sweeping and optimal geodesic path tractography code to ITK as well as the code to provide for volumetric segmentation of DW-MRI data.
See our Project Page for more details.
Approach, Plan
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. Our main purpose at the Project Week is to collaborate on new algorithms and clinical data to provide the best solutions for our DBP partners.
Progress
June 2007 Project Week
During this Project Week, we did a lot of algorithmic design work, focusing on leveraging optimal or geodesic path information to provide for volumetric segmentations of fiber bundles. Working with Marek Kubicki and the Harvard DBP, we were able to begin the process of applying our algorithm to the full cingulum bundle with new labelmaps and to a new fiber bundle - Arcuate. We have recently achieved significant results in volumetric segmentations using a locally-constrained region-based technique (see the images above).
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.
