Design of medical ultrasonic phased array transducer based on PMN-PT single crystal material
摘 要
单晶PMN-PT （铌镁钛酸铅）可有效提高超声换能器的灵敏度和带宽等性能。介绍了一款基于PMN-PT单晶材料的医用超声相控阵换能器，该换能器选用PMN-32% PT （001方向）单晶材料，采用两匹配层结构进行设计。在该基础上制作样品，并对其进行回波信号测试分析。结果表明，所研制的超声换能器中心频率约为2.6 MHz，-6 dB相对带宽为80%以上，具有较好的灵敏度和带宽。

Abstract
Single crystal PMN-PT can effectively improve the sensitivity and bandwidth of ultrasonic transducer. This paper introduces a medical ultrasonic phased array transducer based on PMN-PT single crystal material. The transducer is made of PMN-32%(001) single crystal material and designed with two matching layer structure. On this basis, a single crystal transducer was fabricated, and the echo signal test analysis was performed on it. The results show that the center frequency of the developed ultrasonic transducer is about 2.6 MHz, and the -6 dB relative bandwidth is more than 80%. It has good sensitivity and bandwidth.
