Medical ultrasonography

Medical ultrasonography is a way for doctors to look inside your body to see what's going on inside. It's kind of like taking a picture but instead of using light, they use sound!

Here's how it works: A doctor or technician will put special gel on your skin and then move a small device called a transducer over the area they want to look at. This sends high-frequency sound waves through your body. These sound waves bounce off organs and other body parts, and then the transducer picks them up again.

The computer connected to the transducer takes all of this information and turns it into a picture that the doctor can look at. This picture shows what's happening inside your body and can be used to diagnose problems like heart disease, tumors, and issues with your internal organs.

Don't worry, though - it doesn't hurt at all! And because it doesn't use any radiation like X-rays do, it's very safe for people of all ages to use.
