VOIUS defined by 1: The center of mass of the femur in plane A, which is perpendicular to the shaft axis and intersects the center of the trochanter minor and 2.: The voxel of the femoral head with maximum distance from A. The projected distance between the two points onto the scanner z-axis is used as an anatomic size- and pose-specific distance d. VOIUS contains n = 0.5 d / s (s: slice thickness) slices; the most proximal slice contained the distal end of the acetabulum (not visible here).
