Abstract
Optical scan data including a first set of images representing a first portion of a three-dimensional object is received. A processing device receives ultrasound scan data including a second set of three-dimensional images representing a second portion of the three-dimensional object. The processing device performs image stitching between the second set of three-dimensional images using the optical scan data. The processing device then creates a virtual model of the three-dimensional object based on the stitched second set of three-dimensional images.
Claims3
A method comprising:
- performing an optical scan of a tooth of a patient;
- generating three-dimensional (3D) optical scan data comprising a 3D optical image representing a coronal portion of the tooth;
- performing an ultrasonic volumetric scan on the tooth;
- generating 3D volumetric scan data comprising a 3D volumetric image representing a root portion of the tooth, wherein the root portion is below a gum line of the tooth;
- performing image stitching between the 3D optical image representing the coronal portion of the tooth and the 3D volumetric image representing the root portion of the tooth;
- and
- generating a virtual 3D model of the tooth based on the stitched 3D optical and 3D volumetric images.
