The knowledge of frequency and temperature dependent dielectric properties of tissue is essential to develop ultra-wideband diagnostic technologies, such as a non-invasive temperature monitoring system during hyperthermia treatment. To this end, we characterized the dielectric properties of animal liver, muscle, fat and blood in the microwave frequency range from 0.5 GHz to 7 GHz and in the temperature range between 30 °C and 50 °C. The measured data were modeled to a two-pole Cole-Cole model and a second-order polynomial was introduced to fit the Cole-Cole parameters as a function of temperature. The parametric model provides access to the dielectric properties of tissue at any frequency and temperature in the specified range.
动物肝、肌肉、脂肪和血液的介电特性在微波频率范围 0.5GHz 到 7GHz 以及温度范围 30°C 到 50°C 下的频率和温度相关特性的知识对于开发超宽带诊断技术至关重要,如在热疗期间的非侵入式温度监测系统。为此,我们对动物肝、肌肉、脂肪和血液的介电特性进行了表征。测量数据被建模为双电Cole-Cole 模型,并引入了一个二次多项式来拟合 Cole-Cole 参数作为温度的函数。参数模型可以在指定的范围内的任何频率和温度下获取组织的介电特性。
