Figure 3: Fibers of part of the corpus callosum, computed using the streamlines method (a) and the geodesic ray-tracing method (b). Fibers were computed from seed points located in the center of the corpus callosum and are colored according to their local orientation (similar to the glyphs in Figure 1). Unlike the streamline method, which only captures the most dominant bundles of the corpus callosum, the geodesic ray-tracing method is able to correctly detect the divergence of the fiber bundles. This image was generated in the DTITool [11].
