Ultrasound and its application in medicine and technology

Ultrasound - sound waves having a frequency higher than perceived by the human ear, usually, under ultrasound understand frequencies above 20,000 hertz. Due to the good spread of ultrasound in the soft tissues of a person, its relative harmlessness compared to X-ray rays and ease of use in comparison with magnetic resonance tomography, ultrasound is widely used to visualize the state of the internal organs of a person, especially in the abdominal cavity and pelvis cavity.
