Patent number: 12171614Abstract: For three-dimensional segmentation from two-dimensional intracardiac echocardiography imaging, the three-dimension segmentation is output by a machine-learnt multi-task generator. Rather than the brute force approach of training the generator from 2D ICE images to output a 2D segmentation, the generator is trained from 3D information, such as a sparse ICE volume assembled from the 2D ICE images. Where sufficient ground truth data is not available, computed tomography or magnetic resonance data may be used as the ground truth for the sample sparse ICE volumes. The generator is trained to output both the 3D segmentation and a complete volume (i.e., more voxels represented than in the sparse ICE volume). The 3D segmentation may be further used to project to 2D as an input with an ICE image to another network trained to output a 2D segmentation for the ICE image. Display of the 3D segmentation and/or 2D segmentation may guide ablation of tissue in the patient.Type: GrantFiled: September 29, 2023Date of Patent: December 24, 2024Assignee: Siemens Medical Solutions USA, Inc.Inventors: Gareth Funka-Lea, Haofu Liao, Shaohua Kevin Zhou, Yefeng Zheng, Yucheng Tang

Patent number: 12171635Abstract: A dental appliance includes a base and a coating layer. The base includes a 3D shell-shaped structure configured according to a treatment plan, polymeric materials, and unbound small molecules. The ratio of the weight of the unbound small molecules to the weight of the base is greater than a first predetermined value for improving ductility and toughness of the base. The coating layer is formed over an inner surface and an outer surface of the base. The coating layer surrounds the base and blocks movements of the unbound small molecules.Type: GrantFiled: December 29, 2023Date of Patent: December 24, 2024Assignee: ArtechX Technologies, LLCInventor: Xiang Zhan

Patent number: 12171638Abstract: A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.Type: GrantFiled: January 28, 2022Date of Patent: December 24, 2024Assignee: HANKOOKIN, INC.Inventors: James Jiwen Chun, Angela Soyoung Chun, Andrew Youngho Chun, Jennifer Miseong Chun
