Abstract

We have measured temperature distribution using the infrared optical fibers during radiofrequency ablation (RFA). Infrared radiations generated from the water around inserted single-shaft plain electrode are transferred by the three silver halide optical fibers and are measured by a thermopile sensor array. Also, the output voltages of the thermopile sensor array are compared with those of the thermocouple recorder. It is expected that a non-contact temperature sensor using the infrared optical fibers can be developed for the real time temperature monitoring during RFA treatments based on the results of this study.

用于射频消融的红外光纤温度阵列传感器
利用红外光纤测量了射频烧蚀(RFA)过程中的温度分布。水在插入的单轴平面电极周围产生的红外辐射通过三根卤化银光纤传递,并由热电堆传感器阵列测量。并将热电堆传感器阵列的输出电压与热电偶记录仪的输出电压进行了比较。在此基础上,有望开发出一种非接触式红外光纤温度传感器,用于RFA处理过程中的实时温度监测。
