Abstract
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.
