摘要： Systems (100) and methods (1700) for providing a marker (102). The methods comprise forming a magnetic core (200) having a bone shape defined by two end portions (208, 212) and a center potion (210) 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 (224) is disposed around the center portion. The coil is coupled to a passive electronic component (206) so as to form a resonator. The resonator is disposed in a housing (126) of the marker. The resonator resonates when an interrogation signal is produced by a transmitter circuit (112) located remote from and in proximity to the marker, whereby a variation in a magnetic field occurs.
