Abstract

An apparatus for producing diagnostic x-ray shadowgrams comprising an x-ray source and a gas ionization detector having a gas filling ionizable by x-ray photons, the first absorption edge of said detector gas and the energy level x-ray source being matched so that the x-ray source produces photons of an energy just above an absorption edge of the gas.
