How X-rays work

X-rays are a type of Radiation that can pass throughthe body. They can't be seen by the naked eye and you can't feel them.

Asthey pass throughthe body, the energy from X-raysis absorbed at different rates by different parts of the body.A detector on the other side of the body picks up the X-rays after they've passed through and turns them into an image.

Denseparts of your body that X-rays find it more difficult to pass through, such as bone, show up as clear white areas onthe image. Softer parts that X-rays can pass through more easily, such as your heart and lungs, show up as darker areas.
