“…2b) to assist monitoring of the ablation process, for example, to monitor when the temperature at the tumor edges had increased above 50 • C (T 3 and T 4 ). The simulation showed that at this applied RF energy of 7.5 kJ, the maximal temperature at electrode T 1 was below 100 • C. This is important because of the need to avoid tissue carbonization that impedes or even blocks the RF current and heat transfer into the tissue [10].…”

“…More clinical trials are currently being conducted and mathematical computational models developed to further understand the ablation process and the role of the surrounding tissue and its influence on heat distribution [8]. Most of the reported computational models [9,10] are simplified geometric systems that, though good enough to estimate ablation in FEM studies, do not model the effect of the tissue environment surrounding the tumor.…”

“…For instance, the Finite Elements Method (FEM) has been used to solve many RFA mathematical models [20]- [23]. In this respect, it is crucial to note that prior using a numerical method to solve the HBE, it is necessary to substitute the Heaviside and Dirac distributions (H(t) and δ(t)) for smoothed functions, which can be addressed by FEM.…”
