My doctor wants me to get an ultrasound. What is it?

An ultrasound is a diagnostic medical test that uses high-frequency sound waves to create images of internal organs and structures. It can be used to help diagnose many conditions, including pregnancy, heart disease, kidney disease, and cancer. The ultrasound probe is placed on the body surface over the area being examined, and the sound waves are transmitted into the body. The reflected sound waves are then received by the probe and converted into images.
