Abstract: Disclosed are systems and methods for a computerized framework that provides novel mechanisms for arthroscopic applications using real-time blood flow information. The disclosed framework operates by determining a real-time (or near real-time or substantially simultaneous) visualization of blood vessels or perfusion within anatomical structures during intraoperative procedures, and leveraging this determined information for the performance of an arthroscopic procedure. The disclosed framework can enable an arthroscopic camera to see blood flow and perfusion in tissues in real-time, which allows for differentiation of various parts of the anatomy that may otherwise be undetectable.

Abstract: Methods, non-transitory computer readable media, and surgical computing devices are disclosed herein for creating a three-dimensional (3D) model based on a plurality of received two-dimensional (2D) medical images containing patient anatomy and a tracking fiducial. Once the 2D images are received, a determination is made regarding any potential processing steps required to put the images into a standard view. Once the images are processed, a user may modify or adjust various factors. Using the size and orientation of the tracking fiducial a 3D virtual model is created based on a repository of known patient data, such as a bone atlas. The 3D virtual model can then be output to a display device and optionally used to facilitate a surgical procedure. The 3D virtual model of patient anatomy can advantageously be generated more quickly and using fewer resources with this technology.
