a temperature sensor for online monitoring of radiofrequency thermal
ablation (RFTA). The LCFBG acts as a distributed sensor, with spatial
resolution of 75 μm. A white-light setup that records the LCFBG spectrum
estimates the temperature profile in real time. Three RFTA experiments
have been performed ex-vivo on porcine liver measuring the radial
temperature distribution during the heating process. The analysis of thermal
maps quantifies the spatial heat distribution along the measurement axis and
determines the ablation efficiency.
