X-ray is an imaging test that uses a very small dose of ionizing radiation to produce pictures of the internal parts of the body. Every part of the body can be examined through an X-ray allowing doctors to view and assess conditions ranging from broken bones to pneumonia and cancer. 

X-ray is one of the oldest and most frequently used forms of medical imaging and is an extremely simple, painless, and relatively quick medical test. Traditional X-rays use film to capture images of the body’s internal structures, however, with advances in technology, digital radiography has become a more efficient and safer method of producing diagnostic X-ray images.
