一、超声成像的原理频率在2万赫兹以上的机械振动波,称为超声波(ultrasonic wave),简称超声(ultrasound)。超声成像(ultrasonic imaging)是利用超声波的声成像。目前的医用超声诊断仪都是利用超声波照射人体,通过接收和处理载有人体组织或结构性质特征信息的回波,获得人体组织性质与结构的可见图像的方法和技术。它有自
First, the principle of ultrasonic imaging Frequency of 20,000 Hz above the mechanical vibration wave, known as ultrasonic (ultrasonic wave), referred to as ultrasound (ultrasound). Ultrasound imaging is the use of ultrasound imaging. At present, medical ultrasonic diagnostic apparatuses are all methods and techniques for obtaining visible images of human tissue properties and structures by irradiating the human body with ultrasonic waves and receiving and processing echoes containing human tissue or structural characteristic information.
