Abstract

A method for calibrating or registering a medical instrument or implant includes determining a spatial position of the instrument or implant and determining a relative position of the instrument or implant with respect to anatomical data. A spatial orientation of a multi-dimensionally formed, functional section of the instrument or implant is determined. A device for calibrating or registering a medical instrument or implant using a medical navigation system includes calibration aid, where the calibration aid includes a calibration section whose spatial orientation in said navigation system is known and on which a multi-dimensionally formed, functional section of the instrument or implant can be oriented.
