Ultrasound, or ultrasonography, works on the principle that sound is reflected at different speeds by tissues or substances of different densities. Ultrasound technology has been used medically since the 1940s. Sonograms, the pictures produced by ultrasound, can reveal heart defects, tumors, and gallstones; since low-power ultrasonic waves don't present any risks to a body, they're most often used to display fetuses during pregnancy in order to make sure they're healthy. Ultrasonics has many other uses, including underwater sonar sensing. High-power ultrasonics are so intense that they're actually used for drilling and welding.
