X-RayX-rays are a type of electromagnetic radiation, just like visible light. An x-ray machine sends individual x-ray particles through the body. The images are recorded on a computer or film. X-rays are painless. However, some body positions needed during an x-ray may cause temporary discomfort.
You need to stay still when you are having an x-ray. Motion can cause blurry images. You may be asked to hold your breath or not move for a second or two when they image is being taken.
