ABSTRACT
Human body temperature can be a natural index in diagnosing some diseases. Thermal imaging [Thermography], which works on the basis of infrared radiations, is a fast, non-invasive, non-contact and flexible method for monitoring human body temperature. Additionally, thermal imaging can map the body surface temperature in a non-contact manner. In recent years, extensive research has been conducted with the aim of increasing the use of thermal cameras and obtaining a close relationship between skin temperature and thermal physiology. Thermal imaging has been successful in diagnosing breast cancer, diseases related to blood pathology [e.g., arteriosclerosis, peripheral vascular disease, deep vein thrombosis, effects of vasoconstrictors such as nicotine] - diseases related to joint and bone pathology, and especially in tumoral pathology and pediatrics diseases. This paper investigates the function of thermal cameras, and capabilities and advantages of thermal imaging method in the diagnosis of various diseases.
