Blood perfusion plays a key role for the ablation success, especially in the case of highly vascularized organs like liver. Aim of this work is to evaluate the vessel distance influence on the thermal gradient and the cooling of the tissue caused by blood perfusion during laser ablation. The proposed setup, based on Fiber Bragg Grating sensors (FBGs) around the laser applicator, permitted to measure the heat propagation and to observe a relevant tissue cooling near to the vessel. read more
