Abstract:
Methods and apparatuses for generating a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth) including both surface features and internal features. These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth. Any of these methods and apparatuses may use minimum scattering coefficients and/or segmentation to form a volumetric model of the teeth.

Claim (Index 14):
A method of forming a three-dimensional (3D) volumetric model of a subject's teeth, the method comprising the steps of:\n receiving a plurality of infrared (IR) images of the subject's teeth wherein the plural of IR images are taken with a camera as the camera is moved over the subject's teeth; determining a location and orientation of the camera relative to the subject's teeth for each of the plurality of IR images; generating, for each point in a volume comprising a 3D grid of points corresponding to a volume of the subject's teeth, a density comprising a scattering coefficient that is based on the plurality of IR images and the location and orientation of the camera relative to the subject's teeth; forming a 3D volumetric model of the subject's teeth from the densities; forming one or more iso-surfaces from the densities; and outputting the 3D volumetric model of the subject's teeth.
