中文摘要:
      本文推导了凹球面聚焦换能器产生的声波经耦合液进入软组织后的声场计算公式,并对不同耦合液、耦合层厚度、温度对声聚焦的影响进行了研究,得到了一些对超声热疗具有指导意义的结果。
英文摘要:
      A formula for calculating sound field generated by a concave spherical focused radiator through coupling liquid entering into soft tissues is derived. Effects of different couplants, different widths of coupling layers and temperature on acoustic focusing are studied carefully, and some significant results for ultrasound hyperthermia treatments are reported.
