An ultrasound scan, also referred to as a sonogram, diagnostic sonography, and ultrasonography, is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels.
Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves (ultrasound) to construct an image (sonogram) of internal organs or body structures. In sonography, a transmitting device (the transducer) sends out high-frequency ultrasound waves. Harmless sound waves, which contain no radiation, bounce off the surfaces of the object they hit. The reflected sound forms an echo which is visualized on the screen.
