Abstract:
1. An ultrasonic imaging system for focused harmonic imaging, comprising: a transmitter configured for generating ultrasound which includes a signal component at a fundamental frequency and at least one signal component at at least one harmonic of the fundamental frequency; a wideband transducer configured for converting the ultrasound signal from the transmitter having the included signal components into transmitted acoustic pressure waves including a first portion corresponding to the fundamental frequency and a second portion corresponding to the at least one harmonic frequency of the fundamental frequency, and for directing the first portion and second portion, respectively, to a, first focal zone, and a second focal zone, said transducer further configured for receiving and converting a fundamental frequency response and at least one harmonic acoustic response from the transmitted acoustic pressure waves into at least one response signal; a receiver for receiving at least one response signal; a control system electrically coupled to said transmitter and said receiver, said control system used to control the operation of said transmitter and said receiver; a video processor for converting the at least one response signal to a display signal; and a monitor for converting the display signal into an image.
