| 摘 要： | 在介入式肝癌热疗过程中需要测量组织的热物性参数 ,因此介绍了一种用超小型热敏电阻珠构成的探头的结构特性。探头在测量时既作加热元件 ,又作感温元件 ,测量系统采用负反馈原理。为了给后期测量提供数据 ,对热敏电阻珠本身的温度 /阻值特性进行了研究探索 ,得出温度 -阻值关系曲线。

| Abstract: | Because it is necessary to measure the tissue's thermal properties during invasive hyperthermal treatment for liver cancer,the structure and specialty of a subminiature thermistor probe is introduced.The probe is used as both heating element and temperature measuring element.The principle of measurement system is negative feedback.The relation curve is gained by studying the temperature-resistance characteristic of the thermistor bead itself in order to providing data for the later work. |
