20110255765 | REDUCTION AND REMOVAL OF ARTIFACTS FROM A THREE-DIMENSIONAL DENTAL X-RAY DATA SET USING SURFACE SCAN INFORMATION - A system for removing artifacts caused by x-ray reflective materials from an x-ray image of a patient's teeth. The system includes an x-ray source, an x-ray detector that captures several x-ray images, and a surface scanner that captures a surface scan of the patient's teeth. An image processor generates three-dimensional models from the optical surface data and the CT volumetric data. The models are resized and oriented to be of the same scale and orientation and then overlaid to create a combined data set. Data points that extend beyond the surface of the patient's teeth in the surface model are identified and may be removed if it is determined that they are artifacts. An artifact-reduced CT model is then displayed. | 10-20-2011 |
