ABSTRACT:
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.
