Abstract
An ultrasonic transducer array for harmonic imaging including an ultrasonic transducer array having a plurality of transducer elements, each of said transducer elements having a first surface and a second surface opposite of said first surface, said second surface being non-planar in an elevation direction and said second surface facing away from a region of examination when the transducer is in use. Transmit circuitry is coupled to the transducer array and is operative to cause the transducer array to emit a signal having a bandwidth controlled such that substantially no harmonic energy is transmitted. Receive circuitry is coupled to the transducer array and selectively responsive to harmonic echo information.
