Ampscan compares two 3D scans. This example compares a participant’s socket to the residual limb shape at the start of the study. This shows local press-fit rectifications at the patellar tendon (anterior), the posterior calf/popliteal fossa (posterior), the medial tibial flare, and the tibialis anterior muscle (lateral). The socket is spaced away from the limb at the fibula head (lateral) and the distal posterior surface where the limb has a concave scar geometry. Comparisons between the two shapes are made for volumes, and profiles of cross-sectional area, sagittal width and coronal width vs. % length
