Abstract

A device can read out X-ray information stored in a phosphor layer with an irradiation device for irradiating the phosphor layer with stimulation light which can stimulate the phosphor layer into emitting emission light, and a detector for collecting emission light coming from the phosphor layer and for converting the emission light collected into an analogue detector signal S. In order to increase reliability and resolution when digitising the detector signal, at least two analogue to digital converters are provided which can be operated in different conversion ranges and so can convert the analogue detector signal S into different digital part signal values. Moreover, an analysis device is provided for establishing a digital detector signal value D from the digital part signal values.
