RADIOLUMINESCENT SCREEN WITH IMPROVED QUALITY FACTOR AND SPATIAL RESOLUTION FOR X OR GAMMA PHOTON IMAGING.

摘要

P Radioluminescent screen with improved quality factor and spatial resolution for imaging in X or gamma photons, comprising a transparent plate (2) made of scintillating material in cooperation with an image sensor (16) transforming the light photons produced in the scintillating plate (2) by X or gamma photons in currents feeding a video system, characterized in that the scintillating plate (2) comprises, in its volume, lines (4) of deflection of the light distributed in a perpendicular direction in the plane of the blade, following steps less than or equal to those of the image points of this blade. /P
