CURVED ULTRASONIC HIFU TRANSDUCER WITH COMPLIANT ELECTRICAL CONNECTIONS |
摘要 |
<p>A curved high intensity focused ultrasound (HIFU) transducer comprising a curved piezoelectric array having opposite concave front and convex back surfaces, and a plurality of acoustic transmission areas, a plurality of electrodes located on the convex back surface of the curved piezoelectric array for applying electrical transmit signals to the acoustic transmission areas, and a printed circuit board spaced apart from and in opposition to the back surface of the curved piezoelectric array which couples electrical signals to the acoustic transmission areas, the printed circuit board comprising a plurality of metal contacts which are compliant in the presence of thermal expansion and contraction and which span the space between the printed circuit board and the curved piezoelectric array and are electrically coupled to electrodes of the acoustic transmission areas of the curved piezoelectric array.</p> |
