Abstract: The present invention provides an intraoral X-ray system comprising:



an X-ray source located in an environment;
a robotic arm comprising an actuatable scissor arm, the robotic arm having a first end configured to be attached to a mounting and a second end attached to the X-ray source, at least one of the first and the second ends comprising a rotatable actuatable joint;
a position sensor to determine variation of position and/or orientation of the environment with respect to the X-ray source and variation of position and/or orientation of a mobile X-ray sensor with respect to the X-ray source; and
a driving unit actuating the robotic arm as a function of the determined variation of position and/or orientation to control the position and/or orientation of the X-ray source with respect to a predetermined position and/or orientation of the X-ray source.

Abstract: Method for allowing patient review of virtual restoration element in video of dentition. At least one restoration element for at least one selected tooth of patient dentition is designed using 3D dentition models based on CAD/CAM techniques. Then, real-time video of the patient's dentition including the at least one selected tooth is displayed, where the video orientation is controlled by the patient. Then, the displayed real-time video of the dentition is modified in real-time including the at least one selected tooth to show the at least one restoration element registered to physical teeth in the real-time video of dentition to replace the at least one selected tooth in the modified displayed real-time video of the dentition.

Abstract: The present disclosure describes a Cone Beam Computed Tomography (CBCT) imaging system and methods of operating the system to minimize the degradation of projection images by metal in a scanned object. The methods determine the location of metal in the scanned object by making an initial low dose scan and then, using information obtained from the low dose scan, perform a second scan that may be used to create a reconstruction with reduced artifacts. The methods also calculate X-ray source and detector scan trajectories which minimize reconstruction artifacts and optimize image quality, especially when a region-of-interest is near metal in the scanned object. Additionally, the methods of the present invention calculate X-ray source and detector scan trajectories that maximize the angular range of X-rays which pass through the region-of-interest that are not blocked by metal in the scanned object.

Abstract: The present disclosure describes methods for improving semi-automatic and/or fully automatic tooth segmentation in reconstructed images of X-ray scans using multi-energy X-ray spectra and/or a multi-energy X-ray scanner at more than one energy. Such improved segmentation of teeth in a reconstructed image of an X-ray scan is a critical first step in the utilization of the image for applications in orthodontics, endodontics, and implant planning In accordance with the methods, tooth segmentation may be performed semi-automatically or automatically for images which are reconstructed from a multi-energy X-ray scan. The results of the tooth segmentation may be represented as an image map which identifies voxels which are within a tooth or as a three-dimensional (3D) grid or any other representation of a three-dimensional (3D) spatial region.
