What is X-Ray?

X-Ray is the original field from which radiology developed, and is probably still the most commonly employed form of radiology. X-rays can be either still images or "movies," and can often be done quickly.

The films created by X-rays show different features of the body in various shades of gray. The gray is darkest in those areas that do not absorb X-rays well; the greys are lighter in dense ares (like bones) that absorb more of the X-rays.
