Thermography–a reflector in health and disease

Abstract

The temperature of the skin is dynamic and depends on a number of functions, not least of which is the ambient environment. All objects including the human body emit radiation in the infrared spectrum. Wein’s law states that the rate at which the maximum energy is emitted is dependent on the temperature of the body. Therefore, temperature is reflected by gauging the infrared radiation radiated by the skin surface.3 Thermography, the science of heat recording can be used to record the heat given off by the human body.4
