X-ray

An X-ray machine uses a small dose of radiation to produce images of structures inside the body. The X-rays pass through the area of the body being examined and are translated into images captured on the other side of the body.

What happens during an X-ray?

  1. You will be asked to remove any clothing or jewelry that may interfere with the exam. If you are asked to remove clothing, you will be given a gown to wear.
  2. The area of your body being examined will determine if you sit, stand or lie down on a table.
  3. Areas of the body not being examined may be covered with a lead apron to avoid exposure to the X-rays.
