Fiber-Optic Temperature and Pressure Sensors Applied to Radiofrequency Thermal Ablation in Liver Phantom: Methodology and Experimental Measurements

Figure 24

Pressure (a) and temperature (b) charts reported for three RFA experiments, as a function of normalized time. Experiment 1 is based on the setup of Figure 21(a), and the fiber tip is located at 1 mm distance from the electrode tip. Experiments have been carried out with the setup in Figure 21(b), and the fiber tip-electrode distance is 5 mm and 8 mm, respectively.
