Current Distribution in The Tissue During Electroporation Process

Electroporation is a minimally invasive non-thermal ablation technique used in undesired tissue removal. Even though it has a minimal thermal effect on the tissue, some Joule heating occurs during and after the pulse application. It is highly important and desired to know the actual thermal stress of the tissue in order to prevent coagulation necrosis. The first step towards modelling of the thermal stress is a calculation of electric field intensity and current density. It is necessary to approximate the variable tissue conductivity, which is discussed in this article.
