Abstract

The paper presents a theoretical evaluation of the systematic errors due to the thermal properties of the fiber sensors employed to monitor the temperature increase during liver laser ablation procedures. The opto-thermal finite element model of the laser induced temperature distribution in an exvivo liver is introduced first; then, different types of sensor embodiments are considered and their effects on the temperature distribution evaluated. Both electrical sensors with metallic wires and fiber optic sensors have been analyzed. Temperature errors up to 3 ◦C are expected when a fiber sensor embedded in a glass capillary is employed.
