Temperature profile with time, (A) and (B) for BP in perfused liver and (C) and (D) for MP RFA. BP = bipolar, MP = monopolar, RFA = radiofrequency ablation, W = time in minutes to reach maximum temperature, X = time at which maximum temperature was maintained, Y = temperature difference between (T1 + T2)/2, and T3, T1, and T2 are temperatures on either side of the perfused hepatic portal vein, respectively, and T3 is the temperature of the ablative thermal probe, Z = temperature difference between (T1 + T2)/2 and outlet circulating fluid temperature T4. Tmax = maximum temperature reached during ablation.
