Burns impose one of the most serious injuries to the skin due to the organ's function within the body system and to the body as a whole. In an effort to better deal with the burn wound by the immediate excision and grafting of third degree burns, a high resolution (approximately 0.2 mm) ultrasonic pulse-echo technique was developed for determining burn depth. The experimental subjects were Yorkshire pigs because of the histological similarity between human and porcine skin. Burn depths were readily identifiable immediately postburn with the ultrasonic techniques, as were general trends concerning the burn-viable and viable-fat interfaces. The tissue characteristics, density and acoustic attenuation, effecting the impedance mismatch at the burn-viable tissue interface were investigated. The methods of fluid displacements and specific gravities yielded density values, while spectrum analyses produced attenuation measurements for normal, viable and burned tissue samples.
