In this paper, we propose a method to model radiofrequency electrosurgery capture the phenomena at higher temperatures and present methods for parameter estimation. Experimental data taken from our surgical trials performed on in vivo porcine liver show that non-Fourier Maxwell–Cattaneo-type can be suitable application when used combination with an Arrhenius-type approximates energy dissipation physical chemical reactions. The resulting structure has advantage of accuracy than existing ones, while reducing computation time required.
