X-rays are painless, noninvasive, quick medical tests that produce images of your body to help physicians in diagnosis and treatment of medical conditions. X-rays are a type of radiation made up of electromagnetic waves. X-rays pass through the body and record an image on a special digital recording plate. These digital files can be stored electronically.
Images produced by x-rays vary due to the different absorption rates of different tissues. Calcium in bones absorbs x-rays the most, so bones look white on a film recording of the x-ray image, while soft tissue will appear in shades of gray, and air appears black.

Before Your X-ray
- Please bring a photo ID (driver’s license or state ID), insurance card(s), and a list of your medications with you.
- Bring any x-ray orders from your physician with you.
- Most x-rays require no special preparation.
- You might be asked to change into a gown and to remove jewelry, glasses, or metal objects that could interfere with the x-ray.
- Women should always inform their physician or x-ray technologist if there is any possibility they are pregnant. Caution is taken during pregnancy so as not to expose the baby to radiation.
During Your X-ray
- A technologist specially trained to perform x-ray exams will position you on a table or place you in front of the machine. A lead apron might be placed over you to protect you from radiation.
- You will be asked to hold very still for a few seconds while the x-ray is being taken. The technologist will walk behind a wall or into the next room, and activate the machine. You might be repositioned for another view. A general x-ray is usually completed in five to 10 minutes.
- Afterward, you will be asked to wait until the medical imaging technologist determines that all the required images have been obtained.
