HSC Physics Notes – Medical Physics 9.4 – 1. The properties of ultrasound waves can be used as diagnostic tools 1. identify the differences between ultrasound and sound in normal hearing range Ultrasound is very high frequency sound. Ultrasound waves are sound waves with frequency greater than that of normal human hearing. That is, the frequency greater than → 20 000 hertz. • Sound

Beginning with basic physics of ultrasound, in the presentation how an ultrasound image is constructed is tried to be revealed by investigation of the wave propagation through the tissue.
