From: Augmented reality-assisted systematic mapping of anterolateral thigh perforators
Three-dimensional reconstructed CTA images of the thigh. A Region of interest ranging from ASIS to patella was selected to reveal the whole view of thigh and ALTP. B Volume rendering of the muscles and artery, to display the perforators emerging from the deep fascia. C Different tissues possess different Hounsfield unit (HU) values in CT scan (Bone: 2000-2500HU, Artery: 800-1200HU, Muscle: 50-80HU, Fat: under -140HU). D The diameters of femoral artery, descending branch, perforators, and their cutaneous branches
