Medical ultrasonic probe multielement piezoelectric transducer manufacture method having piezoelectric element isolating element placed/fractioned with grooves dielectric filled and front conductor covering

摘要

The transducer manufacture method has a piezoelectric element (16) with a forward face (22) and rear longitudinal face (26) metallised and polarised. The rear face is placed on an isolating element, and an electrical conductor put on the adjacent face. The assembly (18) is fractioned into sections with grooves across the metallised face and the grooves filled with a dielectric. An electrical conductor covering is applied to the front face.
