Abstract
Various embodiments of the present disclosure identify and correct for magnetic field distortions within a magnetic field for localization of a medical device within a patient. Such magnetic field distortions, often associated with the intrusion of a metallic object into the magnetic field, may cause an unacceptable level of localization error which aspects of the present disclosure correct for.
