Results of the computer simulations. Voltage (A and C) and temperature (B and D) distributions in the tissue. Temperature distributions correspond to the time when maximal tissue temperature reaches 100°C. Figures A and B show the case of a metal blade in electrical contact with the electrode body (t = 3.85 s), while Figures C and D show the case of an insulated (non-conducting) blade (t = 10 s). The voltage applied was of 50 V in both cases. Dashed line represents 55°C isotherm and serves as lesion boundary marker.
