Figure 4
From: Spatial temperature distribution in human hairy and glabrous skin after infrared CO2 laser radiation
The figure illustrates the spatial surface temperature profile at stimulus end (maximum surface temperature) for both mean experimental data (Exp. data) and modeled temperatures based on a finite element model (FEM). A) glabrous skin, 1 W, 0.6 s, 0.6 J/cm2 B) hairy skin, 1 W, 0.6 s, 0.6 J/cm2 C) glabrous skin, 5 W, 0.12 s, 0.6 J/cm2 D) hairy skin, 5 W, 0.12 s, 0.6 J/cm2. In all plots, it is seen that the temperature change 0.6 cm from the beam center at stimulus termination was less than 5°C. Even though the maximum temperature (at the beam center, 0 cm) for the 5 W power setting was approximately the double of the 1 W power setting, the measured and simulated temperature changes more than 0.5 cm from the beam center was identical.
