Abstract
A method for producing a virtual model of a patient includes placing a radiographic template in contact with a first surface of the patient. The radiographic template includes a plurality of radio-opaque markers and a shape of known dimensions. A negative impression of the first surface is formed by the radiographic template. A first CT scan of the radiographic template and said first surface is performed. The radiographic template is removed from the first surface. A second CT scan of the radiographic template apart from the first surface is performed. The first CT scan and said second CT scan are merged to produce an artifact-corrected image. An optical scan of the radiographic template including the negative impression is performed. The artifact-corrected image and the optical scan are merged based on the shape of known dimensions to produce a virtual model of said patient.
