Write application of ultrasonic sound?

Ultrasounds are high frequency waves, which can travel in defined paths even in the presence of many obstacles.

• Ultrasonic waves are used to capture the images of the heart and its features and problems associated with the heart, if any (for treatment purpose). This is called echocardiography.
• Ultrasound scans/Ultrasonography are very commonly used to get images of internal body organs such as liver, kidney, uterus. It helps the doctor to diagnose and treat problems in the body of the patient. In this method, ultrasound waves are made to travel through the body to the organ under consideration. They get reflected and these are converted to electrical signals which can be monitored on a screen.
• Ultrasonography is used to observe the growth of the fetus inside the uterus. It can also used to monitor the abnormalities.
• It is used to break kidney stones into fine grains which later get flushed out through urine.
