Abstract: A system for surgical navigation, including an instrument for a medical procedure attached to a camera and having a spatial position relative to the camera, an x-ray system to acquire x-ray images, and multiple fiducial markers detectable by both the camera and x-ray system, having a radio-opaque material arranged as at least one of a line and a point. A computer receives an optical image from the camera and an x-ray image from the x-ray system, identifies fiducial markers visible in both the optical image and x-ray image, determines for each fiducial marker a spatial position relative to the camera based on the optical image and relative to the x-ray system based on the x-ray image, and determines a spatial position for the instrument relative to the x-ray system based on at least the spatial positions relative to the camera and x-ray system.

Abstract: A system and method for metal artifact avoidance in 3D x-ray imaging is provided. The method includes determining a 3D location of metal in an object or volume of interest to be scanned; estimating a source-detector orbit that will reduce the severity of metal artifacts; moving an imaging system to locations consistent with the source-detector orbit that was estimated; and scanning the object according to the source-detector orbit.
