ABSTRACT
In the mid-1960s and early 1970s, several studies were published indicating the value of IR (infrared) thermography in veterinary medicine [1-3]. In the 1965 research of Delahanty and George [2], the thermographic images required at least 6 min to produce a thermogram, a lengthy period of time during which the veterinarian had to keep the horse still while the scan was completed. This disadvantage was overcome by the development of high speed scanners using rotating IR prisms which then could produce instantaneous thermograms.
