最近人们对超声的生物效应越来越感兴趣，主要是由于超声在诊断医学上取得了惊人的成功。由于超声波在孕期检查中被广泛使用，现在可以预计，未来世界上大部分人口将在出生前接受超声波检查。随着任何环境因素的社会影响的增加，公众对其安全性的关注也在增加。因此，尽管医学超声的安全记录非常好，但各个方面对其可能存在的风险提出质疑也就不足为奇了。现在就有必要继续回答这些问题，尽管我们大多数人很可能更愿意在做出判断之前掌握更多的知识。为了作出回应，一些个人和团体转向科学文献寻求帮助，并试图根据已发表的数据得出结论。在图1中。是美国超声医学研究所（AIUM）生物效应委员会得出的结论。它于1976年被美国医学学会批准，并于1978年再次被稍微修改。
Much of the recent increased interest in bioeffects of ultrasound stems from the astounding success of ultrasound in diagnostic medicine. Because it is so widely used in examining pregnancies, it is now to be expected that much of the future population of the world will have been exposed to ultrasound before birth. As the societal impact of any environmental agent increases, so does public concern about its safety. Hence it is not surprising that questions are being raised from various quarters about possible risks from medical ultrasound, even though its safety record is excellent. It is necessary to respond to these questions now, and continuously, although most of us would very likely prefer to have more knowledge before passing judgements. In order to respond, a number of individuals and groups have turned to the scientific literature for help and have sought to form conclusions based on the published data. In Fig. 1. is a generalization arrived at by the Bioeffects Committee of the American Institute of Ultrasound in Medicine (AIUM). It was approved by the AIUM in 1976 and again, slightly revised, in 1978.
