超声波诊断仪

超声诊断仪是利用人体不同类型组织之间、病理组织与正常组织之间的声学特性差异，经超声波扫描探查、接收、处理所得信息，并以图像、图形或数字形式为医学诊断提供依据的技术设备。由于超声输出对人体会存在一些不确定的损伤，有必要对超声的输出声强进行测量，该项目采用辐射压力法测量，以给临床诊断提供参考。

Ultrasound diagnostic equipment is a technical device that utilizes the differences in acoustic characteristics between various types of human tissues, as well as between pathological and normal tissues. It acquires information through ultrasonic scanning, exploration, reception and processing, and provides a basis for medical diagnosis in the forms of images, graphics or digital data. Since the ultrasound output may cause certain uncertain damage to the human body, it is necessary to measure the output sound intensity of ultrasound. This project adopts the radiation pressure method for measurement, so as to provide references for clinical diagnosis.
