| 1. A device for reading out X-ray information stored in a phosphor layer comprising:
an irradiation device for irradiating the phosphor layer with stimulation light which can stimulate the phosphor layer into
emitting emission light;
a detector for collecting the emission light coming from the storage phosphor layer and for converting the emission light
collected into an analogue detector signal;
at least two analogue to digital converters which are operated in different conversion ranges to convert the analogue detector
signal into different digital part signal values;
an analysis device for establishing a digital detector signal value from the digital part signal values; and
at least one adapter for generating at least two analogue part signals from the analogue detector signal and for respectively
conveying one of the analogue part signals to one of the analogue to digital converters, wherein the adapter comprises a voltage
divider which divides the analogue detector signal into the at east two analogue part signals with a different signal height.
