WebToday X rays are still most widely used in this field. They penetrate soft tissues but are stopped by bones, which absorb them. Thus if a photographic plate that is sensitive to X rays is placed behind a part of the body and an X-ray source is placed in front, X-ray exposure will result in a picture of the internal bones and organs. WebJul 23, 2007 · X-ray imaging. X-rays are a form of electromagnetic radiation. They strike an object and, depending on the density of the object, some of the X-rays will be absorbed.
