A regulatory performance standard for ultrasound therapy equipment has been published by the Bureau of Radiological Health under the authority of The Radiation Control for Health and Safety Act of 1968. To clarify this standard and its intents, a number of topics relevant to the use of ultrasound in physical therapy are discussed, including the physics of ultrasound, equipment output measurements, and the harmful biological effects of ultrasound.
放射卫生局已依据1968年《健康与安全辐射控制法》的授权,发布了一项超声治疗设备的监管性能标准。为阐明该标准及其意图,本文讨论了一些与物理治疗中超声使用相关的主题,包括超声物理学、设备输出测量以及超声的有害生物效应。
