Radiography - Wikipedia

Radiography is an imaging technique using X-rays to view the internal structure of an object. To create the image, a beam of X-rays, a form of electromagnetic radiation, are produced by an X-ray generator and are projected toward the object. A certain amount of X-ray is absorbed by the object, dependent on its density and...
