超声波诊断是一门借助于现代电子技术,超声波技术和电子计算机技术等工程技术来获取人体组织器官对超声波的作用特性,通过超声波某些物理参数的改变、以各种形式反映出人体组织器官解剖学上和某些功能情况的信息做为临床诊断的依据的无损伤性的检查技术,所以在临床医学上得到了日益广泛的应用 Ultrasound diagnosis is a kind of technology that takes advantage of modern electronic technology, ultrasonic technology and electronic computer technology to obtain the effect of human tissue and organ on ultrasound. Through the change of some physical parameters of ultrasound, it can reflect the anatomy of human tissues and organs in various forms Learning and some functional information as a basis for clinical diagnosis of non-invasive inspection techniques, so in clinical medicine has been more widely used
