ABSTRACT:
A method for imaging a target includes the steps of transmitting ultrasonic energy at a fundamental frequency and receiving reflected ultrasonic energy at a harmonic of the fundamental frequency. The transmitted ultrasonic energy is transmitted with a transducer array, and a central transmit waveform associated with a central one of the transducer elements comprises a lower frequency component and a higher frequency component that occur at different times.
