Procedure for Modification of a Head Scan for Cranial Orthosis Design

Cranial orthoses are used to correct an abnormal children's head shape. Although the abnormalities can be clearly classified, their amounts and sizes are specific. This makes orthosis design a highly individual process. It includes adjustment of the head scan to reach a desired shape, which is currently a fully manual task performed using a CAD application, and the result is strongly dependent on a medical technician. In our work we focus on process automatization, which in turn speeds up the designing phase and brings more consistent results. In the future, we plan to include our procedures into the whole design-manufacturing workflow reaching from 3D scanning of the patient's head to the 3D printing of the final product. This will allow production of the orthosis anywhere, without the necessity to have expensive devices in one place.
