Thermography is a noninvasive tool that allows the examiner to visualize and quantify changes in skin surface temperature. An infrared scanning device is used to convert infrared radiation emitted from the skin surface into electrical impulses that are visualized in color. 

This visual image graphically maps the body temperature and is referred to as a thermogram. The spectrum of colors indicate an increase or decrease in the amount of infrared radiation being emitted from the body surface. Since there is a high degree of thermal symmetry in the normal body, subtle abnormal temperature asymmetries can be easily identified.

 The major value is in its high sensitivity to pathology in the vascular, muscular, neural and skeletal systems.  Thermography has been used extensively in the U.S.A., Europe and Asia for the past 20 years.
