Abstract
The current study evaluates radiofrequency (RF) ablation of hepatic tumors with an expandable multi-prong RF applicator. To assess the localized cooling effect of blood flow on necrosis volume, a three-dimensional computational model of hepatic tissue, cancer tumor, blood vessel, and RF applicator was created. The finite element method is used to calculate the effect of blood vessel location, diameter, change in input voltage, and tumor property uncertainty on ablation volume. An increase in blood vessel diameter causes a 6.52% reduction in ablation volume, and a 10 mm diameter blood vessel located next to a tumor causes a 12.19% reduction in ablation volume.
