Radiofrequency thermal ablation (RFA) is a procedure aimed at interventional cancer care and is applied to the treatment of\nsmall- and midsize tumors in lung, kidney, liver, and other tissues. RFA generates a selective high-temperature field in the tissue;\ntemperature values and their persistency are directly related to themortality rate of tumor cells. Temperature measurement in up to\n3ââ?¬â??5 points, using electrical thermocouples, belongs to the present clinical practice of RFA and is the foundation of a physical model\nof the ablation process. Fiber-optic sensors allow extending the detection of biophysical parameters to a vast plurality of sensing\npoints, using miniature and noninvasive technologies that do not alter the RFA pattern. This work addresses the methodology for\noptical measurement of temperature distribution and pressure using four different fiber-optic technologies: fiber Bragg gratings\n(FBGs), linearly chirped FBGs (LCFBGs), Rayleigh scattering-based distributed temperature system (DTS), and extrinsic Fabry-\nPerot interferometry (EFPI). For each instrument, methodology for ex vivo sensing, as well as experimental results, is reported,\nleading to the application of fiber-optic technologies in vivo.The possibility of using a fiber-optic sensor network, in conjunction\nwith a suitable ablation device, can enable smart ablation procedure whereas ablation parameters are dynamically changed
