What is an ultrasound?

Ultrasound comes from a machine that creates an image of the inside of your body. It shows what your baby looks like while still inside your womb (uterus). The moving pictures from the ultrasound machine are like a movie. The pictures appear on a computer screen.

How does ultrasound work?

Ultrasound pictures are made from sound waves which are too high pitched to be heard by the human ear. The sound waves travel through your skin and are focused on a certain part of your body by a scanning device called a “transducer.” It picks up the sound waves as they bounce back from organs inside the body.

Ultrasound is different from x-rays because it does not use radiation. This makes it safer for you and your baby. Ultrasound is used in many areas of medicine.

What will happen during the ultrasound?

If you are scheduled for an ultrasound after your first appointment, we will discuss with you about why we are doing a sonogram and how you will need to prepare.

The person who does the ultrasound is called an ultrasonographer. Once you are lying down on the examining table, clear gel will be put on your skin. The gel allows the transducer to move easily on your skin and helps the sound waves to transmit into your body. You may feel light pressure on your tummy but no pain. Please allow an hour for your ultrasound appointment.

Is ultrasound safe?

Ultrasound has been used on pregnant women for more than 30 years. Studies continue to make sure ultrasound is safe. So far, there is no reason to think that it harms mothers or babies. As with all medical tests, the benefits must always be greater than the risks. (accessed 10/21/13) The Society of Obstetricians and Gynaecologists of Canada: Ultrasound in Pregnancy.
