Infrared thermography. What the human eye cannot see
Most of the diagnostic imaging modalities in medicine utilize portions of the electromagnetic spectrum (Hildebrandt et al., 2010). However, in contrast to other medical devices, infrared thermography uses non-ionising radiation, thus allowing an unconstrained and harmless application in patients. Using infrared radiation, infrared cameras generate thermal images based on the amount of heat dissipated at the skin surface (Hildebrandt et al., 2012). Skin temperatura is related to physiological status, so thermographic technology could help us monitor the physiological status.
