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

An ultrasound is a medical imaging technique that uses sound waves to create images of the inside of the body. It is used to diagnose and treat many different conditions, including pregnancy, heart disease, and cancer. Ultrasounds are performed by a healthcare provider, such as your doctor or nurse, who will use a device called an ultrasound transducer to send out sound waves and then receive the echoes from those waves. The resulting image is then displayed on a monitor for the healthcare provider to interpret.
