摘要： The invention relates to a process for making a multidetector of X-rays forming a plane beam. This multidetector comprises a tight chamber filled with an ionizable gas and, in this chamber, at least one main multidetector assembly comprising a plane conducting plate, electrically insulated from the chamber and a plurality of flat electrodes parallel to the plate, insulated from this plate. This process is characterized in that it consists in making the electrodes, as well as main connections between these electrodes and measuring points outside the chamber enabling the currents circulating respectively in these electrodes to be sampled, on a main face of an electrically insulating plate, these main connections being electrically insulated from the chamber and passing therethrough in tight manner, opposite the source which emits the X-rays. The invention is more particularly applicable to X-ray multidetectors intended for the tomography or radiography of organs or for checking baggage.

摘要： A process for the examination of the flat radiograph of an object irradiated with the aid of an ionizing radiation source is disclosed. In an ionization chamber is detected the latent image of the object formed by the different electrical charges produced in the volume of the chamber under the influence of the impact of the radiation flux which has traversed the object. As this irradiation is continuous, the object to be examined is moved relative to the ionization chamber in the direction and at the migration speed of the ions formed in the electrical field thereof.
