Xeroradiography (xerography, xerography, x-ray with copying, xero-radiography) is a method of obtaining radiographic images in which the image is transferred to film or computer memory using a copying machine.
Unlike conventional radiography, in which X-rays pass through an object and the image is obtained on X-ray film, in the case of xerography, X-rays pass through the object and hit the photosensitive layer of the copier, and then the image is transferred to the film.
This method was invented in the early 20th century and is used to obtain x-ray images of various objects such as bones, teeth, lungs, etc., as well as to create x-rays for dental and orthopedic purposes.
