Abstract
A wireless marker for localizing a target of a patient comprises a casing and a magnetic transponder at least partially received in the casing. The magnetic transponder produces a wirelessly transmitted magnetic field in response to a wirelessly transmitted excitation energy. The magnetic transponder also has a magnetic centroid. The marker also comprises an imaging element carried by the casing and/or the magnetic transponder. The imaging element has a radiographic profile in a radiographic image such that the marker has a radiographic centroid at least approximately coincident with the magnetic centroid.
