What’s thermography?

Thermography and Infrared Light



Since ancient times the detection and monitoring of heat emitted from the body has been used as a diagnostic and management tool. The Egyptians used to monitor skin temperature change by moving their fingers across a body surface. Hippocrates, one of the Ancient Greeks was recorded applying wet mud to a cloth and draping it over the patient’s thorax. He determined that the area to dry first was the problematic point and in so doing took the first ‘thermogram’ over 2400 years ago.

Vets and owners have been feeling and palpating limbs for centuries to gauge where injuries have occured. Temperature difference is such a key indicator, and nothing new in injury detection. What is new, though , is the sensitivity and degree of objectivity that thermal imaging technology provides. It is 40 times more sensitive than the human hand.
