Abstract
An apparatus having a coil of wire, energized by a repetitively pulsed radio frequency (RF) power source to provide electromagnetic fields to a region within a body. A scanning, directional hydrophone acoustically connected to the body, samples ultrasonic radiation generated by the RF fields at the RF frequency or twice the RF frequency induced from conductive spots. Signals from the hydrophone are analyzed with regard to their time of arrival relative to the RF pulses and with respect to their direction of arrival. These collected data are recorded and displayed as images of the spots within the region.
