Abstract
An ultrasonic imaging system for harmonic imaging includes a receiver which demodulates ultrasonic echo signals received by a transducer array and filters a band of fundamental frequencies from the echo signals by means of a notch filter. Images responsive to the filtered signals are presented on a display system.
