Abstract

A calibration block configured to facilitate the calibration of separate surgical fiducial marker arrays on separate medical devices includes a main body having a top face and multiple side faces, top surgical fiducial markers at the top face, side surgical fiducial markers at the side faces, and screw openings at the top face. The top face includes a reference divot configured to accept therein a separate surgical probe tip for separate fiducial marker array calibration. The top and side surgical fiducial markers combine to form a fixed asymmetrical positional arrangement of surgical fiducial markers for calibration. Each screw opening is configured to accept therein a separate surgical screw coupled to a separate surgical screwdriver having a separate surgical screwdriver fiducial marker array coupled thereto for calibration.
