Technical Examples
  1. A system has been described for reading out a plurality of 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 screens being selected from the group consisting of binder containing powder screens and binderless, crystalline or amorphous phosphor layer screens; wherein said phosphors are divalent europium activated alkali halide type phosphors wherein said halide is at least one of bromide or a combination of bromide with at least one of chloride and iodide, or divalent europium activated alkaline earth metal halide phosphors, wherein said halide is at least one of fluoride, chloride, bromide and iodide or a combination thereof, and wherein said screens are consecutively subjected to following steps of stimulating said phosphor screens by means of stimulation energy; detecting stimulated emission energy, emitted by the phosphor screen upon stimulation; converting detected energy into a signal representation of said radiation image; erasing said phosphor screen by exposing it to erasing energy; wherein differences in maximum wavelength of stimulation spectra of said differing screens are in the range from 10 nm up to 100 nm, wherein differences in maximum wavelength of 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.
