摘要
换能器是超声波发射和回波接收器件,是超声医学成像中最重要的声学部件。在医疗超声设备中,换能器直接影响了超声医学成像质量。概述了各种超声医学成像换能器现状,以及换能器聚焦和数字波束成像技术。
Transducer is a part of ultrasound transmission and echo receiver, which is the most important acoustics part. In medical ultrasound instruments, transducers direct affect the imaging quality. This article introduces many kinds of ultrasonic transducers, transducer focus, and digital beam forming technology.
