Equine Thermography

​

Thermal Imaging is a non contact technique that provides a pictorial image of the surface temperature of the horse’s body. Sensors within the thermal camera convert infrared radiation (heat) emitted from the surface of the skin into electrical impulses that are shown on the image as areas of varying colour. White represents the hottest temperature and is found on areas where there is major blood flow including parts of the face and the coronary bands, down through red, yellow, green to blue and finally black which represents the coldest areas. A blue streak indicating a lack of temperature can indicate pinching or nerve restriction, while a red or white area can indicate soft tissue, muscular or tendon damage.

As there is a high degree of thermal symmetry in the horses body, abnormal or asymmetrical changes which are usually indicative of a problem can be easily identified. An experienced Thermographer can interpret these images and advise the owner or trainer where there is an area of abnormal temperature, allowing a veterinary surgeon to diagnose and treat the problem. The procedure only takes a few minutes, during which time the Thermographer takes images of the horse in a specific environment. The horse is not touched during the inspection, making it ideal for young or nervous horses. The results of the inspection are instant, a full written report can be produced for veterinary use.
