What is an Ultrasound?

Vote for this:
Good - Bad


Sound is made up of several different frequency waves. The very high frequency range is inaudible to the human ear and is known as ultrasound.

In each case, an ultrasound machine is used.  With the help of a microphone-shaped device (known as a transducer) ultrasound waves are created and beamed through the body.  The reflected ultrasound waves are collected and analysed by the machine. Knowing the amount of time it took for the beam to travel from and to the transducer, the ultrasound machine can determine the shape, size, density and movement of all objects that lay in the path of the ultrasound beam. The information is presented on a monitor screen and can also be printed on paper.
