Abstract

A camera tracking system is disclosed for computer assisted navigation during surgery. The camera tracking system includes a camera bar, first and second tracking cameras, and a third tracking camera. The first and second tracking cameras are attached at spaced apart locations on the camera bar. The third tracking camera is attached at a location on the camera bar that is between locations of the first and second tracking cameras and spaced apart a distance from a line extending through centers of the first and second tracking cameras.

Description

technical field [0001] The present disclosure relates to medical devices and systems, and more particularly, to camera tracking systems for computer-aided navigation during surgery. Background technique [0002] Computer-aided navigation during surgery can provide the surgeon with a computerized visualization of the current pose of the surgical tool relative to the medical image of the patient's anatomy. Camera tracking systems for computer-aided navigation use one or more stereo cameras to track a set of fiducials attached to surgical tools that are positioned by a surgeon or other user during surgery. The set of fiducials (also referred to as a dynamic reference array) allows the camera tracking system to determine the pose of the surgical tool relative to the anatomy in the medical image and relative to the patient for display to the surgeon. Surgeons can thus use real-time pose feedback to navigate surgical tools during surgical procedures. [0003] Navigating surgical...
