Patent number: 11890063Abstract: Systems and methods for creating images of an environment includes controlling at least one camera to acquire imaging data from the environment and selecting, from the imaging data, a three-dimensional-two-dimensional correspondence as a control point for use in a perspective-n-point problem to determine a position and orientation of the at least one camera from n known correspondences between three-dimensional object points and their two-dimensional image projections in the environment. The method also includes reprojecting at least a selected number of the projections, determining a reprojection error for each of the projections, and performing a weight assignment of reprojection errors to distinguish the inliers form outliers. These steps of the method are repeated to apply the weight assignment to outliers in a decreased fashion during iterations to reduce an impact of outliers in the real-time display of the environment.Type: GrantFiled: December 17, 2019Date of Patent: February 6, 2024Assignee: The Brigham and Women's Hospital, Inc.Inventors: Jayender Jagadeesan, Haoyin Zhou

Publication number: 20230172636Abstract: Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit inside of or next to the tissue mass. The system also includes a second sensor attached to a surgical instrument configured to measure the position and orientation of the surgical instrument. A controller is in communication with the first sensor and the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.Type: ApplicationFiled: December 14, 2022Publication date: June 8, 2023Inventors: Raphael BUENO, Jayender JAGADEESAN, Alan D. LUCAS

Publication number: 20220168046Abstract: Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a surgical instrument and a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit insider or next to the tissue mass. The system also includes a second sensor attached to the surgical instrument configured to measure the position and orientation of the surgical instrument. The second sensor is configured to receive the signal from the first sensor. A controller is in communication with the first sensor and/or the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.Type: ApplicationFiled: July 1, 2021Publication date: June 2, 2022Inventors: Raphael Bueno, Jayender Jagadeesan, Ferenc A.
