Thermal Video SystemsHughes Aircraft Corporation's Probeye Model 3300 Thermal Video System consists of tripod mounted infrared scanner that detects the degree of heat emitted by an object and a TV monitor on which results are displayed. Latest addition to Hughes line of infrared medical applications can detect temperature variations as fine as one-tenth of a degree centigrade. Thermography, proving to be a valuable screening tool in diagnosis, can produce information to preclude necessity of performing more invasive tests that may be painful and hazardous. Also useful in verifying a patient's progress through therapy and rehabilitation.
