Patent ID: 7180086

Claim:
A system for reading out a plurality of differing stimulable phosphor screens, plates or panels, after exposing said screens to X-rays having an energy in the range from 25 up to 150 kVp, the phosphors of which are coated on a substrate in a phosphor layer selected from the group consisting of binder containing powder screens and binderless, crystalline phosphor layer screens; wherein said screens are consecutively subjected to following steps: 1) Stimulating said screens with stimulation light, 2) detecting stimulated emission light, emitted by the phosphor screen upon stimulation; 3) converting detected light signal into a digital representation of said radiation image; 4) erasing said phosphor screen by exposing it to erasing energy; whereby the differences in the position of the maxima in the stimulation spectra of said differing screens are in the range from 10 nm up to 100 nm, whereby the differences in position of the maxima in the stimulated emission spectra of said differing screens are in the range from 10 nm up to 150 nm, and wherein filtering means are provided for preventing stimulation radiation from being detected by detecting means, and for transmitting radiation emitted upon stimulation.
