Objective
- We are developing methods for segmenting the endocardium from the DE-MRI. The current proposed method is a multi-atlas based registration approach. The user is presented with a weighted average of all registered atlas segmentations. The final LA segmentation is a thresholded volume from this weighted average. Weighting is based on the accuracy of the registration, as determined by a mutual information metric.
- There is a prototype module developed by Yi that is currently in Slicer. We propose to expand and tweak this module to specifications determined by our experience using the algorithm on many real patient datasets.
- We will also discuss posssible collaborative paper ideas based on this work.
Approach, Plan
- Improve the speed and accuracy using the multi-scale scheme
- Improve the accuracy of atlas segmentation accuracy with better label fusion techniques.
Progress
The current segmentation module is in the Slicer extension manager.
