An ultrasonic transducer probe comprises an array transducer and a microbeamformer ASIC () containing transmit amplifiers and receive circuitry for operation of the array transducer. For higher power operation, the drive current of the amplifiers is increased, rather than the transmit voltage. The elements of the array present a low impedance to the transmit amplifiers for increased drive current by their construction of thin layers () of piezoelectric material which are electrically coupled in parallel to an amplifier while being mechanically coupled in series for ultrasound transmission.

High power microbeamformer ultrasound transducer probe

A curved high intensity focused ultrasound (HIFU) transducer comprising a curved piezoelectric array having opposite convex and concave surfaces, the concave surface being a transmitting surface, and a plurality of acoustic transmission areas, a plurality of electrodes located on the surfaces of the curved piezoelectric array for applying electrical transmit signals to the acoustic transmission areas, and a unitary, continuously formed curved matching layer pre-formed to the desired curvature of the curved transducer array and bonded to the transmitting surface of the curved piezoelectric array which provides acoustic matching and electrical isolation for the transmitting surface of the curved piezoelectric array.
