The purpose of this preliminary work was to investigate the feasibility to get accurate PRF thermometryimages in the in vivo swine pancreas during laser ablation. We show that PRF thermometry images and consistent temperatures curves can be obtained during the procedure, and these results are confirmed by temperature sensor measurements and histological examination. The presence of a susceptibility artifact (presence of gas bubbles) is discussed.
