Abstract
A system for detecting the position of an object within a body of biological tissue includes a resonant circuit attached to the object and a probe including a receiver/transmitter that operates at the resonant frequency of the object. The resonant circuit rings in response to pulses transmitted from the probe thereby activating receiver circuits which control a visual display indicating the direction the probe should be moved to center it over the object. When the object is centered a second visual display provides confirmation.
