COMPLEX VARIABLE SENSITIVITY ANALYSIS OF THE RADIO FREQUENCY ABLATION PROCESS FOR CANCER TREATMENT

Abstract

The complex Taylor series expansion (CTSE) method is applied in the sensitivity analysis of radio frequency ablation (RFA) procedures, in which the temperature distribution has to be accurately predicted in order to apply proper temperature values to tumor tissue and to avoid unwanted damage of healthy one. For this reason. the CTSE method was used to calculate local sensitivity. In this work, we solve a basic 2D model of the RFA process modelled by the bioheat transfer equation, and coupled with Joule heating equation. The accuracy, robustness and step -size independence are the main advantages of the CTSE method.
