Construction of a low-cost surface scanner for medical studies: a feasibility study
This article reports a three-dimensional (3D) digital color scanning system used in the measurement of facial soft tissue expansion. This system consists of digital scanning equipment, software for stereolithographical (STL) forms and nonuniform rational B-spline (NURBS) surfaces, and a computer-aided design program. Accurate data for the area of scar excision and the expanded cervicofacial flap were obtained by using this measuring system in a young patient with scar contracture of the face. This technique can accurately model the reconstruction and make plastic surgery planning a truly interactive procedure.
