Construction and performance of an experimental phased array acoustic imaging transducer

摘要: Abstract A technique for electrically connecting to the PZT elements in a phased array transducer of cardiac imaging probe is described. The stack consisting substrate with metallized faces and bonded an acoustic absorber across thin alumina proper impedance. sawed into metal foil integrally moulded lens tops form common ground connection. enclosed box electrical connection made by silk-screened metallic conductors on sides box. module two part linen bakelite case which sealed injecting silicone rubber. that was used prepare surface absorber, resulted wide bandwidth transducers, Finally, we show pulse-echo response completed point target water.
