摘要：
The invention relates to a dental computed tomography apparatus which includes an x-ray imaging means and at least one colour camera for photographing the face of a patient positioned at the imaging station of the apparatus from different directions and at least one laser or a corresponding lighting arrangement, which is fitted to direct a light pattern at different locations on the face of a patient positioned at the imaging station, and a means arranged into functional connection with said at least one colour camera for creating a virtual three-dimensional surface model from the light-pattern information directed at different locations on the face of the patient positioned at the imaging station, and a means for combining said face image information detected by said at least colour camera to said surface model of the patients face to create a virtual three-dimensional texture model of the patients face.
