Comparison of temperature profiles at steady state for simulations that incorporate and exclude recursive thermal effects. Figure shows a comparison of the temperature profiles that result from an application of a 30 volt source under steady state conditions (30+hours) for models that exclude and include transient changes resulting from thermal injury (recursive thermal injury). Temperature patterns that include recursive thermal injury far exceed the size of the profiles when recursive thermal injury is ignored. At each time step, the necrosed tissue volume grows, which increases the size of the area of tissue that is unperfused. This pushes the temperature envelope further away from the electrode.
