FIG. 13.
The number of distinct fiber orientations detected within each voxel (98), overlaid on the corresponding anatomical T1-weighted image. Each voxel within the mask is colored according to the number of orientations detected (red: single orientation; green: two orientations; blue: more than two orientations). These results were produced from data obtained from a healthy volunteer, consisting of 15 repeats of 30 DW directions, acquired at b = 1000 s/mm2, analyzed using constrained spherical deconvolution (99) within a “bootstrap” framework (100).
