A two-dimensional virtual simulation of the temperature and electrical field intensity of the balloon-type catheter. (a) Temperature profile of the balloon-type irreversible electroporation catheter at 1500 V (955.4 V/cm); temperature close to the electrode plate is approximately 43 °C; (b) At 2000 V (1274 V/cm), the thermal condition of the electrode boundary is estimated to be about 48 °C; (c) Designed electrical field intensity at 1500 V (955.4 V/cm) showing a rectangular pattern; (d) Electric field distribution delineating the rectangular outline at 2000 V (1274 V/cm). The color bar represents the intensity of the electrical field; red scale, the highest value; and blue scale, the lowest value; (e) A graph illustrating the overall calculated increasing temperature response for 40 pulses in 4 s, which consisted of 100 ms of short pulse delivery with a 900-ms pause, leading to an increase and decrease in the temperature; (f) Elevation and saturation of electrical current during irreversible electroporation ablation at 2000 V (1274 V/cm).
