Abstract :
A periodic variation of the skin surface temperature on the order of one cycle per second with a magnitude of 0.1 degrees C affects the accuracy of quantitative infrared thermography. A recently developed computer-assisted synchronous thermographic system is described that allows detailed and more essential information on the dynamics of physiological functions to be obtained from a time series of thermograms without any effects due to temperature variation. Computer simulation reveals that this surface-temperature variation corresponds to the pulsatile change of blood flow through arterioles in the dermis.<>
