In this work, we report on the integration of fiber Bragg gratings sensors in a commercial radio frequency probe for real-time temperature monitoring during thermal ablation of biological tissues. The experiments were conducted on ex-vivo pig liver and bovine kidney tissues and the results confirm that the proposed setup is able to conduct a multi-point real-time temperature monitoring during the RF discharges with a temperature resolution of 0.1 °C and a minimum spatial resolution of 1 mm. During these experiments the blood perfusion was implemented by injecting water at a temperature of 37 °C inside the organ under examination. This solution aimed at simulating the Radio Frequency Thermal Ablation (RFTA) treatments made in clinical practice. © 2018 IEEE.

Abstract

In this work, we report on the integration of fiber Bragg gratings sensors in a commercial radio frequency probe for real-time temperature monitoring during thermal ablation of biological tissues. The experiments were conducted on ex-vivo pig liver and bovine kidney tissues and the results confirm that the proposed setup is able to conduct a multi-point real-time temperature monitoring during the RF discharges with a temperature resolution of 0.1 °C and a minimum spatial resolution of 1 mm. During these experiments the blood perfusion was implemented by injecting water at a temperature of 37 °C inside the organ under examination. This solution aimed at simulating the Radio Frequency Thermal Ablation (RFTA) treatments made in clinical practice. © 2018 IEEE.
