摘要： A system has been described for reading out stimulable phosphor screens, plates or panels, whether or not differing from each other in phosphor composition or phosphor layer arrangement, after exposing said screens to X-rays. Said system comprises at least one source of stimulating radiation, an array of transducer elements arranged for detecting light emitted upon stimulation and for converting said light into a signal representation of said image. Said system further comprises filtering means for preventing light, emitted by said source of stimulation light, from being detected by said transducer elements, wherein said filtering means transmits light with a high transmission efficiency for emitted blue light upon stimulation and low transmission for radiation from the stimulating laser source.
