  1. 1 – The maximum electrical conductivity for the case of 0% perfusion was located along the center of the conducting electrode. In all other cases, the maximum temperature occurred at the tip of the probe; 2 – The units for tissue perfusion are cubic meters of blood (mb 3) per cubic meter of tissue (mt 3) per second.
