An X-ray can be used in a variety of ways.
According to the Mayo Clinic, an X-ray is "a quick, painless test that produces images of the structures inside your body." X-rays can be used for a variety of purposes; they are helpful in the medical, dental and aerospace industries.
Diagnosis
X-rays are commonly done to diagnose a variety of medical problems, such as broken bones, fractured bones, arthritis, infections, enlarged organs, problems with the digestive tract and tumors. Additionally, X-rays can be used to locate an item that has been accidentally swallowed.
Treatment
Occasionally, X-rays are also used to treat a disease. For example, some forms of cancer are treated by delivering strong doses of X-ray radiation to the cancer cells, thereby killing them.
Evaluation
After an X-ray has been used to diagnose a problem, it can also be used to evaluate the effectiveness of the treatment. For example, an X-ray can be done to scan the chest to see if antibiotics have effectively treated a chest infection.
Dental Health
According to the American Dental Association, X-rays allow dentists to examine the structures underneath the visible oral tissues. In doing so, dentists are able to discover hidden dental problems at an earlier stage.
Science
The National Aeronautics and Space Administration (NASA) explains that X-rays can be used to study astronomy. In fact, many things in space, such as black holes, comets, the Sun and the stars, emit their own X-rays that can be detected by satellites.
