Determining the locations of therapeutic seeds implanted in a body part by distinguishing the therapeutic seeds from the body part by imposing physical changes on the therapeutic seeds and sensing these physical changes in the therapeutic seeds. In one form of the invention, the therapeutic seeds are partially ferromagnetic and are caused to vibrate by a magnetic field and the vibrating therapeutic seeds are identified by reflections of ultrasonic signals transmitted to the therapeutic seeds.
