Publication number: 20220012888Abstract: The present disclosure describes a system and methods for autonomous segmentation of volumetric dental images, such as those produced by an imaging system, The methods, implemented by the system, acquire a volume image of a patient and extract a volume of interest comprising patient dentition from the acquired volume image. A first plane is extended through maxillary portions of the patients jaw and a second plane through mandibular portions of the patients jaw. A maxillary sub-volume is generated from the volume of interest according to the first plane and a mandibular sub-volume from the volume of interest according to the second plane. Maximum intensity projection images are formed for each sub-volume and teeth are delineated from these images. Teeth are segmented within each sub-volume according to the tooth delineation for their respective sub-volume.Type: ApplicationFiled: November 14, 2019Publication date: January 13, 2022Inventors: Shoupu CHEN, Wei YE

Publication number: 20210343020Abstract: 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.Type: ApplicationFiled: October 11, 2019Publication date: November 4, 2021Inventors: Jay S.
