Publication number: 20230097249Abstract: Systems and methods for providing at least one fixture for use in an image guidance system for determining a registration coordinate mapping between a human jaw and a volumetric image of that jaw. The system includes one or more channeled trays and a moldable thermoplastic material for inserting into a channeled tray. The moldable thermoplastic material is hardenable into an impression part such that when mated to the at least a portion of the human jaw and held within the channel of the channeled tray, the impression part resists displacement relative to the human jaw. At least one channeled tray in the system includes a fiducial region detectable in the volumetric CT image in a fixed spatial relation relative to the coupling surface region and at least one channeled tray is pose-trackable by the image guidance system.Type: ApplicationFiled: September 19, 2022Publication date: March 30, 2023Inventors: Doron Dekel, Arish Qazi

Publication number: 20220175463Abstract: A system and method of operating a surgical navigation system to determine the location of a point of interest (POI) in a 3D coordinate frame of a surgical tool (tool frame) using a calibrated imaging device to capture an image of a portion of the surgical tool's surface the calibrated imaging device having calibration data that enables a processor of the surgical navigation system to map from a 2D location in the image to a projection line in a 3D coordinate frame of the imaging device (image frame). The system is operated to determine a mapping between an image frame and a tool frame. The processor is operated to determine the location of the POI in the tool frame based on the image and the mapping between the image frame and the tool frame.Type: ApplicationFiled: December 2, 2021Publication date: June 9, 2022Inventors: Doron Dekel, Arish Qazi

Patent number: 10463321Abstract: An apparatus, method and kit are provided for registering a human jaw with a CT image of the human jaw. The apparatus includes a moldable retainer and an arm having a moldable link portion and a rigid fixation portion. The link portion is attachable to the retainer and hardenable to maintain a fixed mapping between the fixation portion and the retainer. The fixation portion includes a CT marker connection region for detachably attaching a CT marker that includes a fiducial. The fixation portion also includes a tag connection region for detachably attaching a tag that is trackable by a pose measurement system. The pose of the tag connection region relative to a pose of the CT marker connection region is fixed prior to attaching either the tag or the CT marker, providing a known and fixed tag to fiducial coordinate mapping.Type: GrantFiled: December 8, 2015Date of Patent: November 5, 2019Assignee: CLARONAV INC.Inventors: Doron Dekel, Arish Qazi, Ido Bermanis
