Thermal decay response right after the euthanasia was within 15 % of the thermal response obtained after 12 hours of death in the head of human sized porcine models. Thermal decay over time is a function of thermal properties alone (i.e., thermal conductivity, density, and specific heat). Thus, the thermal decay response measurements suggest that the variation in the thermal properties was less than 15% after 12 hours of death. This further suggests that the RF heating related thermal responses obtained with in 12 hours of death in fresh, perfused cadavers may closely mimic thermal responses in live humans.
