| 1. A computer-implemented method for detection of fiber pathways comprising:
determining a subset of voxels selected from an input diffusion tensor image by applying a threshold to fractional anisotropy
values of the voxels;
determining a cluster of points with collinear diffusion directions;
performing region growth to find seed points in a plane that is normal to the cluster's mean direction, starting from a center
of the cluster;
tracing pathways from the seed points;
eliminating voxels of the subset that are close to the pathways using a distance threshold;
displaying a visualization of a selection of voxels used as seed points; and
displaying a visualization of the pathways traced from the seed points.
