摘要： In a method for producing CsX:Eu stimulable phosphors and screens or panels provided with said phosphors as powder phosphors or vapor deposited needle-shaped phosphors suitable for use in image forming methods for recording and reproducing images of objects made by high energy radiation, said CsX:Eu stimulable phosphors are essentially free from oxygen in their crystal structure, wherein X represents a halide selected from the group consisting of Br, Cl and combinations thereof; and wherein the method further comprises the steps of mixing CsX with a compound or combinations of compounds having as a composition CsxEuyX′x+αy, wherein the ratio of x to y exceeds a value of 0.25, wherein α≧2 and wherein X′ is a halide selected from the group consisting of Cl, Br and I and combinations thereof; heating said mixture at a temperature above 450° C.; cooling said mixture, and, optionally, annealing and recovering said CsX:Eu phosphor.

摘要： Method of eliminating the effect of afterglow on a radiation image read out of a photostimulable phosphor screen. For each pixel the amount of afterglow generated by previously scanned pixels in the same line of pixels is determined and subtracted from the digital signal representation of that pixel.
