Infrared thermography: A non-invasive method for medical examinations

Thermal imaging, also called thermography is the production of infrared or “heat pictures” by utilizing an infrared camera. Based on these thermal images, accurate temperature measurements can be made to detect even the smallest temperature differences when looking at human bodies.

Human body temperature is a complex phenomenon. Man is homeothermic, and produces heat, which must be lost to the environment. The interface between that heat production and the environment is the skin. This dynamic organ is constantly adjusting to balance the internal and external conditions, while meeting the physiologic demands of the body.

Numerous medical specialists have discovered that infrared is a reliable and quick non-invasive method to detect hot spots, as this technique provides a visual map of skin temperatures in real time. Infrared is widely accepted as an accurate and reliable tool for medical assessment and diagnosis. Able to measure differences in the surface temperature of the skin as small as 0.08°C, one of the obvious applications of infrared thermography is to detect whether a person has a fever or not. Changes in the thermal conductivity of the skin caused by burns, skin ulceration or grafting have also been detected and monitored with a sensitive thermal imaging system.


    • Back spasm

    • Open heart surgery
    • Early detection of skin cancer
    • Pain management
    • Burn depth assessment
    • Ligament injuries

    N.B. Infrared thermography should only ever be used for medical diagnosis in conjunction with a qualified medical professional.
