The Performance and Material Selection of Medical Ultrasonic Transducer

With the accelerating pace of mordern medicine, the various transducers that applicat in clinical diagnosis are also more and more, most medical ultrasonic transducer using acoustoelectric transducer to emiting and receiving of ultrasonic wave. However, the selection of transducer’s material is very important to the performance of medical ultrasonic transducer. This paper describes structures and properties of the medical ultrasonic transducer, and a variety of quantitative indicators that influence its performance. Aim to work out the most appropriate material for making the medical ultrasonic transducer.
