Reading an X-Ray
Different parts of the body absorb X-rays in varying degrees. Dense bone absorbs much of the radiation while soft tissue, such as muscle, fat and organs, allow more of the X-rays to pass through them. As a result, bones appear white on the X-ray, soft tissue shows up in shades of gray and air appears black – making it easy to differentiate the various parts of the body and identify bone abnormalities or injuries. Special care is taken to use the lowest dose of radiation possible. Today’s advanced X-ray systems have significant filtration and dose control methods to minimize stray or scatter radiation. This ensures those parts of the body not being imaged receive minimal radiation exposure.
