Other embodiments are also described. | 2021-10-14 |
20210315642 | COMPUTER-ASSISTED ARTHROPLASTY SYSTEM - A computer-implemented method for creating an activity-optimized cutting guides for surgical procedures includes receiving one or more pre-operative images depicting one or more anatomical joints of a patient, and creating a three-dimensional anatomical model of the one or more anatomical joints based on the one or more pre-operative images. One or more patient-specific anatomical measurements are determined based on the three-dimensional anatomical model. A statistical model of joint performance is applied to the patient-specific anatomical measurements to identify one or more cut angles for performing a surgical procedure. A patient-specific cutting guide is created that comprises one or more apertures positioned based on the one or more cut angles. | 2021-10-14 |
20210315643 | SYSTEM AND METHOD OF DISPLAYING IMAGES FROM IMAGING DEVICES - A system and method of displaying images from an imaging device includes a display device and one or more processors. The one or more processors are configured to track movement of an imaging device, determine a display-device-to-imaging-window transform based on the tracked movement and a corresponding command to move the imaging device, and render an image received from the imaging device on the display device at a position and orientation on the display device based on the display-device-to-imaging-window transform. In some embodiments, the display-device-to-imaging-window transform is determined based on at least one of a difference between: a commanded and an actual position of the imaging device, a commanded and an actual orientation of the imaging device, a commanded and an estimated position of the imaging device, or a commanded and an estimated orientation of the imaging device. | 2021-10-14 |
