    摘要: 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.

    摘要: The invention relates to a method of reading out information items stored in a phosphor layer, in which the phosphor layer is excited to emit emission light and the emission light is sensed by a detector and the detector is moved relative to the phosphor layer. During this process, the detector consecutively senses the emission light emitted in each case by individual regions of the phosphor layer. To reduce the dark noise and the movement blur, provision is made that the detector senses the emission light emitted by a region during an integration time that is less than a forward-travel time for the movement of the detector by the width of the region in the forward-travel direction (V).

    摘要: The present invention reduces the influences of electromagnetic fields during reading out of image signals from memory phosphor films. This is done by pre-amplifying the detection signals obtained from a detection device, in particular a CCD array, before further processing, for example by an analog-to-digital converter. An amplification register for electron multiplying can be used for the amplification. In this way individual photon sensitivity can be achieved when reading out X-ray images.
