Infrared Fiber-Optic Temperature Array Sensor for Radiofrequency Ablation

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.
