More Information
Summary:A method for detecting and correcting for magnetic field distortions within a magnetic field used for medical magnetic localization systems may include a first set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils within the metal distortion detection fixture at a first time received from the metal distortion detection fixture. A first magnitude value of the combined signals is determined. A second set of one or more signals is indicative of the magnetic field sensed by each of the sensor coils at a second time is received and a second magnitude value of the combined signals is determined. A magnetic shift in the magnetic field between the first and second magnitude values is determined. The magnetic shift is compared to a threshold shift amount indicative of a magnetic distortion in the magnetic field.
