The non-thermal, non-cavitational (NTNC-) effects of medical ultrasound are based essentially on the direct and indirect effects of the sound radiation pressure. This article introduces the biophysics of the basic mechanisms and describes possible clinical implications using selected examples. It has been determined that generally no additional risks ensue through the effects of NTNC used purely for diagnostic purposes. Significant effects can only be detected under the conditions which prevail during therapeutic exposure. The question as to whether the pulse Doppler technique is completely harmless cannot be answered conclusively at this time. The synergetic effects between ultrasound and contrast media have not yet been examined thoroughly.
医学超声的非热、非空化（NTNC-）效应主要基于声辐射压力的直接和间接效应。本文介绍了基本机制的生物物理学，并通过选定的示例描述了可能的临床意义。已经确定，纯粹用于诊断目的的NTNC效应通常不会带来额外风险。只有在治疗性暴露时存在的条件下才能检测到显著效应。关于脉冲多普勒技术是否完全无害的问题目前尚无定论。超声与造影剂之间的协同效应尚未得到充分研究。
