Abstract

The present invention relates to an X-ray detector adapted to detect rays having passed through an object or an organ. This detector comprises at least one main tight chamber containing a gas ionizable by X-ray and, in this chamber, a plate for collecting the charges resulting from ionization of the gas. It comprises a secondary ionization chamber, coupled to the main chamber to compensate the scattering current.
