Visualization of body thermoregulation by infrared imaging

This paper analyzes two mechanisms applied on the human body in order to study the thermoregulatory system according to heat generation and heat loss. Two approaches are presented. The first approach is based on plethysmography, where an armband is placed on the forearm in order to modulate the blood flow. The second approach uses a cold stimulation. The visualization is achieved using infrared imaging devices. The resulting images reveal a temperature balance between the stimulated and the non-stimulated hands. The thermal behavior and typical thermographic recordings on each subject are discussed and analyzed in response to different stimulations.
