Abstract
Radioluminescent screen with an improved quality factor and spatial resolution for X or gamma photon imaging having a transparent plate (2) made from a scintillating material cooperating with an image sensor (16) transforming the light photons produced in the scintillating plate (2) by X or gamma photons into currents supplying a video system, characterized in that the scintillating plate (2) has in its volume light deflecting lines (4) distributed in a direction perpendicular to the plane of the plate, in accordance with spacings equal to or smaller than those of the image points of the said plate.
