Abstract
An x-ray phosphor plate system has an x-ray phosphor plate, which is configured to be exposed by x-ray light in a recording region, and which carries a shadowing marker, which is arranged in the recording region, on at least one side of the x-ray phosphor plate. The system also has a phosphor plate reader, which is configured to read the exposed x-ray phosphor plate in order to produce an x-ray recording. The shadowing marker has a shadowing effect in respect of x-ray light that is so small that the shadowing marker is only weakly identifiable, and/or only identifiable by way of image artefacts, and/or not identifiable when the x-ray recording is observed by a user. The phosphor plate reader instead has an identification algorithm, which is configured to identify whether or not the x-ray light was shadowed by the shadowing marker during the exposure.
