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

Figure 21

Experimental setup for pressure/temperature measurement in RFA procedure. (a) EFPI/FBG probe inserted through a hollow ablation device in plain liver phantom. (b) Fiber-optic probe inserted perpendicularly to ablation direction through an external catheter; liver tissue is confined in an XPS chamber.
