'''Objective:''' Semi Automatic Segmentation and parcellation for the Basal Ganglia.<br />
<br />
'''Progress:''' We have developed an algorithm for delineation of the striatum into 5 physiological subregions (pre/post caudate, pre/post putamen, and nucleus accumbens) while requiring only minimal user input. We have implemented this algorithm from the geometric rules for delineating the striatum as defined by our Core 3 collaborator, Dr. James Levitt of the PNL, into a 3D SLICER module. The current run time for the algorithm is ~20 seconds after the initial user input. The user inputs a label map of the full striatum, the most superior/dorsal voxel of the putamen on each slice, and the anterior commisure voxel (see figure below). From these, the labelmap is delineated into the aforementioned subregions. The figure below shows a 3D model of the left and right striatum delineated into the five subregions.<br />
