Abstract :
A dual extrinsic Fabry-Perot interferometer fibre Bragg grating (EFPI/FBG) pressure and temperature sensing architecture, biocompatible and with minimum cross-sensitivity, is presented. The system performs online monitoring of radiofrequency thermal ablation in liver tumor, detecting the physical phenomena; ex-vivo experiments are reported.
