摘要
超声发射和接收电路是超声检测仪的关键组件,系统的性能及精度很大程度上取决于这两部分电路的设计。人体软组织特性超声检测仪器由于其被测介质的特殊性其发射和接受电路又有其特殊的要求。本文分析了超声波仪器的发射和接收电路的基本原理。并提出了人体软组织特性超声检测仪器一种可行的解决方案。
The application of ultrasound is com prehensive.The transmitter and receiver are key components of ultrasonicdevice.The performance and precision of the system are depen dent on the design of these two circui ts.The design of ultrasonic device for measuring soft tissue of human body is special due to the special measured media.The basic principles of the tr ansmitter and receiver are studied,and a new design of the circuit for detecting the soft tissue by using the new electronic elements is proposed.
