Abstract

Microwaves are currently being investigated as a method of inducing hyperthermia. Values of the relative permittivity and conductivity of mouse muscle and tumour tissues over the frequency range 50 MHz to 10 GHz at a temperature of 37 degrees C are reported. The data were obtained by using an on-line computer-based time-domain spectrometer. The tumour tissues were the RIF/1 and KHT fibrosarcomas sited in the hind leg muscle of C3H mice. A significant difference in the relative permittivity between the normal and tumour tissue was shown to exist at frequencies up to 200 MHz.

摘要

目前正在研究将微波作为一种诱导热疗的方法。报告了在37摄氏度下，频率范围为50兆赫兹至10吉赫兹的小鼠肌肉和肿瘤组织的相对介电常数和电导率值。这些数据是通过使用基于计算机的在线时域光谱仪获得的。肿瘤组织是位于C3H小鼠后腿肌肉中的RIF/1和KHT纤维肉瘤。结果表明，在高达200兆赫兹的频率下，正常组织和肿瘤组织之间的相对介电常数存在显著差异。
