An X-ray image is produced when a small amount of radiation passes through the body and strikes a sheet of sensitive film placed on the other side of the body. The ability of X-rays to penetrate tissues and bones varies according to the tissue’s composition and mass. Bone, which contains calcium, does not let much radiation through and results in white images on the X-ray film. The lungs, which are filled with air, allow nearly all X-rays to strike the film resulting in a black film image.
Generally, for plain X-rays, there is no preparation. As with any medical procedure, be sure to inform your physician or the technologist if there is any possibility that you are pregnant or if you have a history of allergies.
Depending on the area of your body to be X-rayed, you may need to change into a gown or pajamas upon arrival. When you have an X-ray, it will usually require at least two views of the body part to be taken. Occasionally, multiple views are taken.
