3D Modelling

How It Works The VECTRA® 3D camera and Sculptor™ software which make this possible were developed by Canfield Imaging Systems of Fairfield, NJ, the world's leading provider of medical photography systems. The process starts with a VECTRA 3D session, which produces a three dimensional photograph of the patient.
