Abstract

The in vitro dielectric properties of human fetal organ tissues were measured in the frequency range from 100 kHz to 500 MHz at 24 degrees C. The dielectric measurements were performed by using a network analyzer (HP4195A) and a coaxial line capacitive sensor. The tested samples, including skin, muscle, heart, lung, liver, kidney, spleen, and brain tissues, were obtained from the legal abortion of five women with 14-16 weeks gestation periods.

摘要

在24摄氏度下，测量了人胎儿器官组织在100千赫兹至500兆赫兹频率范围内的体外介电特性。介电测量使用网络分析仪（HP4195A）和同轴线电容传感器进行。测试样本包括皮肤、肌肉、心脏、肺、肝脏、肾脏、脾脏和脑组织，取自5名妊娠14 - 16周的妇女的合法流产胎儿。
