摘要
超声理疗设备在设计和检测过程中经常出现较多超声输出功率问题,例如超声输出功率不准确,相关参数未标记等。文章对超声理疗设备的超声功率输出相关参数的测量方法进行解读,主要包括超声输出功率和时间最大输出功率的测量与计算,换能器的有效辐射面积的测量与计算,以及对辐射力天平的使用注意事项等。
Ultrasound physical therapy equipment always has many problems with the ultrasonic output power during the design and testing process,such as inaccurate ultrasonic output power,and the relevant parameters are not marked.This article will interpret the measurement method of the related parameters on the ultrasonic power output of ultrasonic physiotherapy equipment,mainly including the measurement and calculation of ultrasonic output power and temporal-maximum output power,the measurement and calculation of the effective radiating area of the transducer,and precautions for the use of the radiation force balance.
