dc.description.abstract We present a miniature and biocompatible fiber-optic sensing system, for specific application in monitoring of the radiofrequency thermal ablation (RFA) process. The sensing system is based on combination of Extrinsic Fabry-Perot Interferometry (EFPI) sensor for pressure detection, and Fiber Bragg Grating (FBG) for temperature measurement. The dual pressure/temperature measurement shows an extremely low cross-sensitivity. Measurements have been performed ex-vivo on porcine liver, recording several RFA procedures in different location. Maximum values of 164°C and 162 kPa have been recorded on the ablation point. en_US
