Abstract
A surgical viewing system including an X-ray source, a screw placing surgical tool, a detector, a fiducial marker, and an image correction system. The X-ray source creates a beam of radiation, and the surgical tool is coupled thereto. The X-ray detector detects an image, the detected image resulting from receiving a portion of the radiation. There is at least one fiducial marker coupled to a part of the surgical tool, the fiducial marker being radiopaque and blocking a portion of the beam of radiation from the detector to produce a profile on the detected image. The surgical tool has an axis of rotation and the fiducial marker is axially symmetric to the axis of rotation. The image correction system takes the detected image and produces a corrected image by using a shape of the profile of the fiducial marker and/or a location of the profile of the fiducial marker.
