  1. Simulated lesion dimensions with no tissue perfusion at an ambient temperature of 22°C using a 63% cell damage threshold (D) were compared to experimental measurements made at 20, 25, and 30 volts using an experimental constant voltage radiofrequency ablation source. Lesions were generated with a single needle ablation probe with a 2.0 cm active electrode. All lesion measurements were measured visually under a micrsope at 10× magnification.
