MULTI-ELEMENT X-RAY DETECTOR, RARE-EARTH X-RAY PHOSPHOR FOR SAID DETECTOR, METHOD OF MAKING MULTI-ELEMENT SCINTILLATOR AND DETECTOR ALTOGETHER Russian patent published in 2011 - IPC G01T1/20 

FIELD: physics.

SUBSTANCE: multi-element X-ray detector, consisting of a flat multi-element scintillator in form of a discrete set of hetero-phase luminescent elements placed in grid cells made in form of metal which absorbs X-rays and reflects light, the spacing of which coincides with the photodetector array pitch, a metal grid which forms a multi-element luminescent scintillator made from elements with atomic number ranging from N=26 (iron) to N=74 (tungsten), has silver plated coils and optically separates elements of the scintillator from each other. The coils have diametre between 0.06 mm and 0.16 mm. The cross-sectional area of the grid is between 45% and 82%.

EFFECT: high contrast of the obtained integral image.
