Example of DIERS formetric 4D surface topography scan using a mannequin. a The left (DL) and right sacral dimples (DR) associated with the posterior superior iliac spine were added to the mannequin using modeling clay before scanning (inset). b A grid of lines is projected onto the surface of the back and images are captured by the DIERS formetric 4D instrument. c The technician verified that DL and DR were clearly and accurately localized on the 3D model created by the DIERS formetric 4D instrument
