BRAINSCut

Back to NA-MIC Brains Collaboration

Summary: BRAINSCut is a software package for segmentation of structures using artificial neural networks. Currently this tool supports the segmentation of the following structures: caudate, putamen, thalamus, hippocampus, anterior cerebellum, interior posterior cerebellum, superior posterior cerebellum, corpus medullary. Future regions will include the globus pallidus, amygdala, and nucleus accumbens. The command line uses the Slicer3 execution model framework.

Progress:

1. Integration with a high dimensional registration to the atlas probability map
2. Improved thresholding of the output activation maps
3. Code added to NITRC

To Do:

1. Link to a BSD style Neural network library
2. Look at the ability to use for segmentation of cortical regions
