3D foot surface scanning for the purpose of foot orthotics production

Orthopedic and generally individual insoles are often used for the treatment of deformities, and other pathological conditions that manifest themselves in the foot, or to improve the performance of people who spend a lot of time standing or walking. Insoles are intended to reduce the burden resulting from the ground reaction, to improve propulsion and stability of walking, and to compensate the deficit due to static deformity or present pathology. [1] Numerous studies have shown the benefits of individual approach to making insoles towards application of over the counter ones. Among the most important parameters on which to base the development of insoles or molds is implementation of volumetric measurements. Volumetric measurementsin the classical approach are based on taking footprints in wet sand or clay. Over time, these methods have been upgraded and now are in use polyurethane foam boxes in which foot is immersed, and later poured gypsum solidification gives grounds for mold. In addition, the classical approach often encounters using plaster bandages wrapping around the foot to form "slipper cast." By pouring plaster into this structure and its solidification we also get mold. These methods are still often found in use in orthotic practice. With the development of digital technology, this practice have begun to introduce new solutions that improve the practice by saving time of making insoles and reducing the discomfort which the patient may have during the measurement process. The application of digital measuring technology enabled CAD/CAM manufacture of orthopedic insoles (or molds). Although there are numerous solutions present in the market, there is still a great need for more accessible devices that enable wider applicationin practice.
