Quantitative assessment percentages. Percentages are displayed as function of curvature (upper) or FA (bottom) and for the superficial (right) and deep (left) compartment.

Example of the masks to determine the quantitative assessment. The aponeurosis is indicated in black and the derived masks for the superficial (medium grey) and deep (light grey) compartments. The near border mask is indicated in dark grey.

Fiber trajectories for subject 3 before (a) and after (b) quantitative assessment. Note the yellow fibers in both compartments in a. The aponeurosis is indicated in blue and fibers originating from the deep aspect of the aponeurosis are indicated in shades of yellow, while fibers originating from the superficial aspect of the aponeurosis are indicated in shades of green. Color variations within the tracts exist only for contrast.

Three dimensional representation of the aponeurosis, with colors indicating fiber tract assessment. The distributions are depicted for the deep (a) and superficial (b) aspects of the aponeurosis for subject 3. The perspective is 180° rotated between the two. FT_Complete: green; FT_less: yellow; FT_Crossed: red; FT_Length: white; FT_Premature: blue; not tracked: black.
