An X-ray is a type of electromagnetic radiation that is used to see inside the body. It's named for the x-shaped pattern that the beams make when they pass through body tissue.
X-rays are produced when a high-energy electron beam strikes an anode (a piece of metal) inside a vacuum tube. The beam passes through a target, such as human tissue, and causes it to fluoresce. This fluorescence is then detected by a photographic plate or by electronic detectors and turned into an image.
