The normal internal temperature in resting man is maintained within very narrow limits, inspite of wide variations in the environmental temperature. Under steady state condition heat flows from production site in the body to cooler tissues and blood distributes this heat to the body surface from where it is dissipated to the external environment by radiation, convection and evaporation. The importance of deep body temperature as an indicator of disease has been known for centuries; but in recent years attention has been paid to the significance of skin temperature. So thermography was developed, which is a measuring technique that portray surface temperature distributions pictorially, painlessly and is free of radiation. This is accomplished either with liquid crystals or infrared scanning equipment. This technology lost favour some 20 years ago, but with new ultra sensitive high resolution digital infrared devices, efficacy is much improved. This poster presentation is an attempt to show that modern thermography can also be used as an adjunctive diagnostic and preventive medicine tool.
