Abstract:
An ultrasonic contrast agent and tissue imaging system, comprising:a transducer with transmit and receive bandwidths centered about a fundamental frequency; a first transmitter to generate a first pressure wave at the fundamental frequency, the first pressure wave having a first intensity; a second transmitter to generate a second pressure wave at the fundamental frequency, the second pressure wave having a second intensity, wherein the second intensity is different than the first intensity; a receiver to receive ultrasound signals reflected from an object in a medium; a control system electrically coupled to said first and second transmitters and said receiver, said control system used to control an operation of said first and second transmitters and said receiver; a processing system electrically coupled to said receiver to detect both a first and a second response generated by acoustic reflections from the object in the medium, the first and second responses resulting from the first and second pressure waves respectively, wherein the processing system is configured to generate a projected response from the first response and to mathematically manipulate the projected response and the second response to derive the nonlinear response; and a display system electrically coupled to said processing system to display an image derived from the non-linear response.
