How does an Ultrasound work

Avimaging18 Dec, 2020Health

Ultrasound is similar to the sonar that ships and submarines use to show what's in the water around them. With medical ultrasound, a wand-like-instrument called a transducer sends out waves of high-frequency sound. As these sound waves pass through the body, certain structures like organs, tissues, and tumors reflect the wave back. That reflection, or echo, is then used to create a picture of what's ahead.
