From: Augmented reality-assisted systematic mapping of anterolateral thigh perforators
Augmented reality (AR) for ALTP flap design. A The points a-f were marked on the 3D CTA images. B The points a-f were marked on the muscle surface. C The marked images were imported in the portable projector, and then mapped onto the thigh surface before operation. D Doppler ultrasound and AR were used to depict the perforators and emerging points, to facilitate the ALTP flap harvest
