How are ultrasound waves produced

WebIn ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). WebUltrasound is sound with a frequency greater than 20,000 Hz. Humans cannot hear ultrasound but many other animals can, such as mice, dogs and porpoises. Ultrasound …
