Infrared Fiber-Optic Temperature Array Sensor for Radiofrequency Ablation

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.
