Patent number: 11272845Abstract: The invention generally relates to medical imaging systems that instantly and/or automatically detect borders. Embodiments of the invention provide an imaging system that automatically detects a border at a location within a vessel in response only to navigational input moving the image to that location. In some embodiments, systems and methods of the invention operate such that when a doctor moves an imaging catheter to a new location with in tissue, the system essentially instantly finds, and optionally displays, the border(s), calculates an occlusion, or both.Type: GrantFiled: October 7, 2013Date of Patent: March 15, 2022Assignee: PHILIPS IMAGE GUIDED THERAPY CORPORATIONInventors: AJ Cheline, Fergus Merritt, Asher Cohen, Elizabeth Begin, Nathaniel J.

Patent number: 11272151Abstract: Embodiments disclose a real-time surgery method and apparatus for displaying a stereoscopic augmented view of a patient from a static or dynamic viewpoint of the surgeon, which employs real-time three-dimensional surface reconstruction for preoperative and intraoperative image registration. Stereoscopic cameras provide real-time images of the scene including the patient. A stereoscopic video display is used by the surgeon, who sees a graphical representation of the preoperative or intraoperative images blended with the video images in a stereoscopic manner through a see-through display.Type: GrantFiled: October 7, 2021Date of Patent: March 8, 2022Assignee: OnPoint Medical, Inc.Inventor: Carlos Quiles Casas

Patent number: 11266327Abstract: A method comprises generating an image of a set of connected passageways of a patient anatomy and modeling the set of connected passageways of the patient anatomy as a structure of linked bounded-surface elements. The method also comprises receiving position information for a point on an instrument indicating a position of the point relative to the connected passageways and generating adjusted position information for the point including comparing the received position information to the structure of linked bounded-surface elements. The method also comprises creating an adjusted instrument image with the adjusted position information and generating a composite image including the image of the set of connected passageways and the adjusted instrument image.Type: GrantFiled: May 3, 2019Date of Patent: March 8, 2022Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Vincent Duindam, Prashant Chopra
