Abstract
Systems () and methods () for providing a marker (). The methods comprise forming a magnetic core () having a bone shape defined by two end portions () and a center potion () disposed between the two end portions. The end portions each have a cross-sectional area larger than a cross-sectional area of the center portion. A coil () is disposed around the center portion. The coil is coupled to a passive electronic component () so as to form a resonator. The resonator is disposed in a housing () of the marker. The resonator resonates when an interrogation signal is produced by a transmitter circuit () located remote from and in proximity to the marker, whereby a variation in a magnetic field occurs.
