A new method using a semiconductor strain guage is described for the measurement of the acoustic power output of ultrasonic medical therapy and other probe heads. The acoustic power output of the probe heads is found to be linearly related to the calibrated electrical output of the strain gauge transducer system, as expected theoretically. The instrument developed is inexpensive, portable and easy to operate for the routine measurement of ultrasonic output of the equipment in hospitals.
本文描述了一种使用半导体应变片测量超声医学治疗探头及其他探头声功率输出的新方法。如理论预期，探头的声功率输出与应变片换能器系统的校准电输出呈线性关系。所研制的仪器价格低廉、便于携带且易于操作，可用于医院设备超声输出的常规测量。
