由于医疗诊断和治疗超声设备的使用越来越多，对这些设备的输出水平的准确测量对于制造商和用户变得重要。这种测量是重要的，原因有几个。首先，存在与诊断和治疗超声相关的可能的健康风险问题。在生物效应研究中，需要精确测量超声水平，以便其他研究人员可以重复实验。此外，期望已知临床使用的设备的输出，以便其可以与报告的生物效应相关（Nyborg，1977; Stratmeyer，1977; Stewart等人，1977; Stratmeyer和Stewart。1979年）。其次，测量程序对于超声波设备的校准是必要的（例如，治疗仪器），其中需要为各种治疗提供已知的曝光。第三，从设备性能的角度来看，了解设备的超声输出与其他性能参数（如成像能力）的关系是很重要的。第四，如果管理机构要评估设备以确保符合性能标准的适当校准，则需要精确的测量方法（联邦登记册，1978，1979; Repacholi和本韦尔，1979; Stewart等人，1999年）。例如，1980年）。
The accurate measurement of the output levels of medical diagnostic and therapeutic ultrasound equipment have become important to manufacturers and users as a result of the increasing use of these devices. Such measurements are important for several reasons. First, there is the question of possible risk to health associated with diagnostic and therapeutic ultrasound. Accurate measurements of ultrasound levels used in biological effects investigations are needed so that other investigators can repeat the experiments. In addition, it is desirable that the output from equipment in clinical use be known so that it can be related to reported biological effects (Nyborg, 1977; Stratmeyer, 1977; Stewart et al., 1977; Stratmeyer and Stewart. 1979). Second, measurement procedures are necessaryfor the calibration of ultrasonic equipment (e.g., theraphy instruments) in which there is a need to provide a known exposure for various treatments. Third, it is important from the standpoint of equipment performance to know the ultrasonic output of equipment in relation to other performance parameters such as imaging capabality. Fourth , accurate measurement methods are needed if regulatory agencies are to evaluate equipment to ensure the proper calibration in compliance with performance standards (Federal Register, 1978, 1979; Repacholi and Benwell, 1979; Stewart et. al., 1980).
