超声医学的发展有赖于超声生物效应的研究,而超声生物效应的研究是为了提供一个保障人体健康的剂量标准,并探讨其作用的物理机理。本文作者用超声辐照家兔肝脏,观察其超微结构的变化,深入研究医学诊断用超声波的生物效应,并探索超声与生物组织相互作用的物理机理。 The development of ultrasound medicine relies on the study of ultrasound biological effects, and the study of ultrasound biological effects is to provide a dose standard to protect human health and to explore its physical mechanism. In this paper, we use ultrasound to irradiate the liver of rabbits and observe the changes of their ultrastructure. We study the biological effects of ultrasound for medical diagnosis, and explore the physical mechanism of the interaction between ultrasound and biological tissues.
