X-Rays for Children X-ray radiography is a safe, painless diagnostic test that uses X-rays, which are a form of electromagnetic energy, just like visible light. A machine sends individual X-ray particles through the body, and a computer records the images that are created. Wireless technology at Randall Children's Hospital provides your physicians with the highest quality image, delivered twice as quickly as other hospitals. This allows your physician to give you a more timely and accurate diagnosis. The speed and sophistication of our imaging systems is especially important for children's trauma cases, when every moment counts. What can I expect? We'll do everything we can to make your child comfortable during the scan. The body part being X-rayed is positioned on a surface with an X-ray cassette underneath or behind it. Then the X-ray beam is focused on the area of interest using a beam of visible light. A body part is always scanned from at least two different angles, since each image is only two-dimensional. FAQs How will it feel? There is no sensation from the X-ray. It's important that your child hold as still as possible during the scan, usually about 1 second, because movement can blur the image. Your child may be asked to hold his or her breath very briefly. How should I prepare my child? Your child will be asked to remove jewelry and wear a hospital gown.
