Ultrasound of time average acoustic intensities between 0.5 and 3 W cm-2 is widely used in physiotherapy. A simple device for semiquantitative checking of output power and beam shape has been designed. The beam tester consists of an absorbing plate and a sheath liquid crystal thermometer for temperature distribution display. The ultrasonic beam is fed to the absorber through a simple water tank.
0.5至3瓦每平方厘米之间的时间平均声强超声在物理治疗中被广泛应用。已设计出一种用于半定量检查输出功率和波束形状的简单装置。波束测试仪由一块吸收板和一个用于显示温度分布的鞘状液晶温度计组成。超声束通过一个简单的水箱被输送到吸收器。
