Scanning systems designed to capture three-dimensional (3-D) in-vivo images of the topographical features of feet using laser or light scanning systems or a combination of both. These systems typically consist of a stand-alone unit or a handheld wand that is displaced along the foot contour to scan and capture images from plantar and surrounding areas, a central unit that process the numerical data and 3-D images, and a monitor that displays the video images in real time. The systems simultaneously record the digital data corresponding to the images as a digital foot impression using dedicated software. Once the digital impression is assessed, it is sent electronically to a computer-aided manufacturing milling machine that may be located in the same orthopedic area or in a remote orthopedic laboratory for automated manufacturing of the model of an appropriate orthosis or prosthesis.
