An ultrasound is a painless diagnostic test that most women will receive during pregnants. High-frequency sound waves travel into your uterus, and they bounce back from the fetus as vibrations. The echoes are translated into electrical signals that are projected as black-and-white pictures on a monitor. The images display your baby’s soft tissues and organs.
Transabdominal Ultrasound: After arriving at your appointment, the sonographer will smear a clear gel on the skin of the addomen. The gel allows the transducer (a handheld device that looks like a microphone) to slide more easily over your belly, and it improves the transmission of sound waves into your body.
Next the sonographer moves the transducer along your abdomen, applying some gentle pressure. The transducer transmits sound waves that create a picture of the baby inside. If you’re ticklish, you might find yourself challenged during this procedure. Take a deep breath and try to relax!
