Various embodiments of the present disclosure are directed to an apparatus for generating a magnetic field for tracking of an object. The apparatus may include transmitting elements that generate a desired magnetic field (when combined) in an area of interest, and a rapid decaying magnetic field in a separate area. The separate area can be adjacent to the area of interest and can include a magnetic field-disrupting component.

Localized magnetic field generator

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.
