Abstract
In a photostimulable storage phosphor screen or panel wherein said screen comprises storage phosphor particles dispersed in a binder and wherein said particles have a particle size distribution having a dwhich is not more than 15 μm, said dexpressing a grain size limit above which not more than 1% by weight of phosphor powder particles is present in said phosphor powder, its structure noise parameter DQEexceeds a value of 0.70 and a ratio of d(expressed in μm) and DQEis not more than 25:1, wherein DQEis the ratio of the DQEobtained at a dose of 22 mR to the DQEobtained at a dose of 3 mR, as expressed in formula (I)DQE2rel=DQE2(22 mR))/DQE2(3 mR)  (I)which is representative for an amount of screen-structure noise produced by said screen or panel in the complete spatial frequency range.
