Ultrasound uses echoes from high-frequency sound waves to produce a picture of the inside of your uterus. Our technician first applies a gel-like substance to your abdomen and rubs a wand-like instrument called a transducer through the gel.
You see an image on a computer screen from the echoes of the sound waves that bounce back. Depending on how far along you are, the technician will point out what you’re seeing and listen for a heartbeat.
