Thermography is used in industry, outer space, the military, by your local HVAC guy, and for medical screening. Currently, thermal imaging is in the news because of temperature-screening devices used in airports. As businesses, social venues, and event and travel spaces develop safer protocols for gathering people, temperature screening has become widespread. Temperature screening thermography uses a variety of devices ranging from low-end handheld scanners up to medical-grade devices with the same detailed specifications required for evaluation of human and veterinary patients. High-end temperature screening systems use facial recognition software to calculate body temperature from the medial canthus of the eye, which is the most accurate superficial point for evaluating core body temperature.1 These systems measure temperatures from six feet away, allowing for safe, contactless use. Further, they "flag" elevated temperature; the person then undergoes a secondary screening protocol. Medical thermography is more than 70 years old. Early devices were expensive, cumbersome, and not practical for widespread clinical application.
