Abstract: Systems, devices, and methods for segmentation of patient anatomy are described herein. A method can include receiving a three-dimensional (3D) scan volume including a set of images of a 3D region of patient anatomy. The 3D region of patient anatomy can include a set of anatomical structures. The method can also include generating a set of two-dimensional (2D) radiographs using the 3D scan volume. Each 2D radiograph from the set of 2D radiographs can include 3D image data extracted from the 3D scan volume. The method can also include training a segmentation model to segment 2D radiographs using the set of 2D radiographs to identify one or more anatomical parts of interest.

Abstract: A surgical navigation system can include a three-dimensional (3D) display system with a see-through screen; a tracking system configured to track the position and orientation of a surgeon's head, the see-through screen, a patient anatomy and a medical device to provide current position and orientation data; data associated with an operative plan, patient anatomy, and/or the medical device; a surgical navigation image generator configured to generate a surgical navigation image with a three-dimensional image including a first virtual image indicating the planned position and orientation of the medical device according to the operative plan data and a second virtual image indicating a current position and orientation of the medical device.

Abstract: The present disclosure relates to cantilevered imaging modality wearable optical systems that provide for optimal ergonomics coupled with vision enhancement and vision magnification. Methods of use, devices, and kits are also contemplated.
