How do doctors use sound?
When ultrasound waves bounce off objects, they reflect back in the form of echoes. These echoes can be interpreted by machines, which then produce images of the objects the sound waves bounced away from. Using these images, doctors can see the size, shape and location of internal organs such as the liver.
