Automatic quantification of a CA map in the left AF region of native space. A single region of interest to enclose core voxels of the left AF (orange contour of the top left panel) is manually delineated on the MNI FA template (gray-scaled image in the top left panel). This region of interest is then transferred to individual CA maps (colored images) via the corresponding Mi−1(x,y,z). At each transferred region of interest, the sum of AP (green) and ML (red) components are calculated and compared across the subjects to quantify the degree of WM development in the left AF.
