• A simulation of tumour ablation in liver tissue is presented. The ablation is produced by a thin coaxial antenna excited at microwave (MW) frequency. The electromagnetic field and the specific absorption rate (SAR) are calculated by the finite element method. Then, the thermal bio-heat equation (BHE) is solved by assuming the SAR as heat source. The presence of blood vessels in the examined domain is investigated by considering the convection-diffusion BHE. Some test cases are finally proposed to evaluate the influence of the blood velocity on the temperature distribution.
