I've heard that if I'm pregnant, my doctor will want to do an ultrasound to check the baby's development. What does that procedure involve?

An ultrasound is a diagnostic medical test used to visualize internal organs and structures of the body. During an ultrasound, a transducer emits sound waves which are reflected off of the tissues being scanned. The resulting images are then displayed on a monitor for interpretation by a healthcare professional.
