Xeroradiography is a type of X-ray imaging in which a picture of the body is recorded on paper rather than on film.
In this technique, a plate of selenium, which rests on a thin layer of aluminium oxide, is charged uniformly by passing it in front of a scorotron.
The resulting imprint, in the form of charge distribution on the plate, attracts toner particles, which is then transferred to reusable paper plates.
In contrast to conventional X-rays, photographic developers are not needed.
