Dependence of McA-RH7777 hepatocellular carcinoma cell viability on current density and treatment energy. a With constant pulsed E field parameters of 20 kV/cm and a pulse number of 100, the ablation response is inhibited when less than 50 A/cm² is flowing through the hepatocarcinoma cells; b. Percent viability 3.5 h post treatment versus the total treatment energy generates curves that are very similar for most applied E fields, suggesting that it is the energy delivered to the cell rather than the E field that is the more critical parameter for determining ablation efficacy
