DIFFICULTIES OF THERMOGRAPHIC MEASUREMENTS IN MEDICINE. The infrared thermography imaging is one of possibilities of temperature analyzing. Infrared thermographic imaging is unique in the principle of contacless measurement, so it is often used in medicine and science. The principles of this method lies in the detection of electromagnetic radiation which energy corresponds with temperature of analyzed objects. Using thermographic systems and surface temperature measurements can be affected by some errors. The basic errors include wrong or insufficient assessment of parameters, which affect the temperature of the displayed object. These factors are mirrored temperature, emissivity, and ambient temperature, for example. In the article, we documented effects of these errors and the ways of their elimination.
