Tau image: a diagnostic imaging technique based on the dynamic digital telethermography

A new diagnostic imaging technique based on the dynamic digital telethermography is described. Using all the functional information related to the local thermoregulatory process, this technique seems able to detect and to classify the stage of some disorders that alter the normal displays of the local thermoregulatory system. The presence of these altering pathological factors can be enhanced by means of an induced thermal stress and recorded by the different dynamics of the thermal recovery exhibited by healthy or damaged area. The recording of these different recovery dynamics-performed by means of digital thermographs characterised by a very short acquisition time-can provide a new useful imaging tool, especially to validate and to follow up specific rehabilitative processes
