FLIR imaging was first developed in 1956 with military funding at the University of Chicago. From the 1960s into the 1970s, FLIR technology was modified independently by both the Air Force and Texas Instruments Inc. for use by military planes (2). Wendell Smith first documented the use of thermal imaging in medical diagnosis in 1964. Smith required 6 minutes to take each thermograph of the horses he was studying (3). Multiple veterinary studies have been performed since then, and now thermal imaging has been validated as a means to assess musculoskeletal injuries in animals (4,5).
