Clinical monitoring of flaps relies on skin color, capillary refill, and turgor to provide visual evidence of flap perfusion. Recognizing the visual cues of a failing flap early enough to successfully salvage the tissue requires considerable clinical experience. IR thermography is widely used in clinical medicine as a noninvasive technique to measure skin temperature.

It is a matter of fact that moisture excess highly contributes to the decay of a building. Actually, most historical buildings are affected by such a problem. It is well known that the evaporation process, with the migration of salts within the material, represents the main reason for the deterioration of surfaces.

In recent years, infrared thermal imaging technology has made remarkable progress, and its image quality has been significantly improved. Thermography is a non-contact, non-invasive diagnostic imaging method, which provide on the basis of temperature patterns and the evaluation of temperature asymmetry in different regions of the body, physiopathological pain information and therefore establish precisely the type of pain.
