Investigation of radiofrequency ablation process in liver tissue by finite element modeling and experiment = Radijo dažninės kepenų audinio destrukcijos procesų matematiniai ir eksperimentiniai tyrinėjimai

Abstract

Background. The character of ablation processes with high-frequency electricalcurrent is similar in most biological tissues; however, quantitative characteristics are very different. Consequently, mathematical models of the process have a lot of specific aspects. In this study, we developed mathematical model of radiofrequency ablation in liver tissues with experimental validation of model in ex vivo porcine liver.
