Abstract

The present invention relates to a detector of X-rays having passed through an object or an organ. This detector comprises at least one tight ionization chamber containing a gas ionizable by the rays issuing from the object and, in this chamber, a plate for collecting the charges and a series of electrodes for collecting the charges resulting from the ionization of the gas. The ionization chamber further contains a gas capable of creating, within the mixture thus formed, a movement of gas opposite the movement of the ions.
