Table 4 Percent Error between Constant Conductivity and Temperature Dependent Data without Perfusion

From: Finite Element Analysis of Hepatic Radiofrequency Ablation Probes using Temperature-Dependent Electrical Conductivity

Applied Volts (V) Maximum Temperature Achieved (°C) Change Electric Field (%) Change Current Density (%) Change Temperature (%) Change Heat Flux (%) Change Electrical Conductivity (%) Change SAR (%)

20.0 94 -3.2 120.2 5.7 10.7 127.5 113.2
  1. Percent error for all cases is calculated as (<Temperature Dependent Parameter> – <Constant Parameter>) / <Constant Parameter>. All percentage changes refer to the maximum change in the parameter.
