Abstract
Ultrasonics denotes mechanical vibrations at frequencies of approximately 16 kHz to 1 GHz. Because of its quasi-optical propagation behavior, in medicine and technical applications, ultrasonics is chiefly used to image or detect objects. The two acoustic parameters determining the transparency or the ability of the ultrasonic wave to penetrate matter are absorption which indicates the quantity of ultrasonic energy transformed into heat in the specimen, and scattering. Scattering means that an ultrasonic wave when striking an obstacle radiates part of its energy in all spatial directions.
