Embodiment Construction

[0024] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or shown in the following drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways.

[0025] Figure 1A is a block diagram illustrating components of a system for removing artifacts from a three-dimensional digital CT model of a patient's teeth. The system can also be used to create 3D digital models of the patient's jaw and other facial bones and tissues. The system includes an X-ray source 101 and an X-ray detector 103 . An X-ray source 101 is positioned to project X-rays towards the patient's teeth. The X-ray detector 103 is placed on the opposite side of the patient's teeth - either in the patient's mouth or on the opposite side of the patient's head. The X-rays from

Abstract

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.
