The cameras () of this X-ray detector are all mounted on a common rigid plate () by a surface support and screwed to ensure their optical distance from a scintillator () itself mounted on the plate () by an enclosure () forming a darkroom (). The common mounting of the principal elements of the detector on a single rigid plate thus significantly reduces image deterioration produced by deformations of the detector, of thermal or mechanical origin.

X-ray detector comprising a plurality of cameras sharing common field of view

A screen panel for converting X-rays into light photons includes a rigid foam plate ( ), a first layer ( ) of composite material located on one face of the rigid foam plate ( ) and a second layer ( ) of composite material located on the other face of the rigid foam plate, parallel to the first face. The screen panel applies, for example, to medical radiology and to non-destructive testing of nuclear waste storage packages.

Screen for converting X-rays into light photons

A semiconductor detector including at least one block of detector pixels, each detector pixel being composed of a semiconductor element with a first face covered by a first armature and a second face covered by a second armature. The detector pixels are assembled side by side such that the first armatures define a detector plane. The first armatures are covered by a plane conducting structure that connects them together electrically. The detector does not have any dead area in which detection is impossible. The semiconductor is particularly applicable to detection of ionizing radiation (gamma rays, X-rays, etc.)

Detector with semiconductor for detecting ionizing radiation having a plane conducting structure

This device comprises a liquid radioactive source which, when the patient is absent, is used for calibrating the ionizing radiation detectors of the apparatus and is located in a container which can contains the source. The device comprises a storage magazine communicating with the container by at least one pipe and means for transferring the liquid source from the storage magazine to the container and vice-versa, the container being fixed with respect to the apparatus and the magazine having a volume at least equal to that of the container.
