X-rays are a type of electromagnetic radiation that can be sent through the body to show images of internal structures. X-rays are an important diagnostic tool for a wide range of issues from abdominal or chest diseases to orthopedic issues in bones or joints.
There are different types of medical X-ray imaging used for different medical diagnostic needs. Fluoroscopy is one type of medical X-ray imaging that shows a continuous X-ray image on a monitor, much like an X-ray movie.
X-rays use invisible electromagnetic energy beams to make images of the skull. Standard X-rays are done for many reasons, including diagnosing tumors, infection, foreign bodies, or bone injuries.
X-rays use external radiation to produce images of the body, its organs, and other internal structures to diagnose a problem. X-rays pass through body tissues onto specially treated plates (similar to camera film). It makes a "negative" type picture is made. The more solid a structure is, the whiter it appears on the film. Computers and digital media may be used in place of films.
When the body undergoes X-rays, different parts of the body allow varying amounts of the X-ray beams to pass through. Images are produced in degrees of light and dark, depending on the amount of X-rays that penetrate the tissues. The soft tissues in the body (such as blood, skin, fat, and muscle) allow most of the X-ray to pass through and appear dark gray on the film. A bone or a tumor, which is denser than the soft tissues, allows few of the X-rays to pass through and appears white on the X-ray. At a break in a bone, the X-ray beam passes through the broken area and appears as a dark line in the white bone.
