Thermography is used for early detection and monitoring of abnormal physiology. It is a safe and non-intrusive procedure using technology developed by NASA. Thermography does not require radiation, compression, contact, or intravenous injection, unlike other imaging modalities.
A camera and scanning device are used to convert infrared radiation emitted from the skin surface into electrical impulses that are visualized in color on a monitor. This visual image graphically maps the body temperature detecting abnormal chemical and blood vessel activity in body tissue.
Thermography is useful in detecting many conditions. Thermography can be used for any region of the body where there is pain, inflammation or other physiological problems. Variations from these normal values are measured and correlated with suspected injuries or diseases in the same way a blood or urine laboratory study is interpreted. It was approved by the FDA in 1982.
