Step 1: Connected components of right leg (VOIRC) for G = 1 (a) and G = 3 (b) (G: Grade of muscle appearance, see text). Step 2: Probable muscle voxels within processed left leg (VOILC) (c) and compactification resulting in VOIIFA (d and e) (IFA: Approximation of IF). Step 3: refinement of VOIIFA. Candidate voxels close to FA that may belong to VOIIF (f and g), seed points to select clusters that belong to VOIIF (h), clusters that were not selected stay porous (i) and are removed by morphological smoothing yielding the final result (j). User-dependence is indicated by blue color.
