摘要:
The invention relates to a system having a scanner and a memory layer. The memory layer comprises particles for storing X-ray information items, that can be excited by a stimulating radiation to emit an emission radiation corresponding to one of the X-ray information items and that are embedded in a medium and are distributed over the entire thickness of the memory layer. The scanner comprises an irradiating device for irradiating a linear region on the memory layer and a detector for the positionally resolved detection of emission radiation emitted by the memory layer along the linear region. To increase the sharpness of the X-ray information items to be detected with low losses in the intensity of the emission radiation, the medium can at least partially absorb components, directed both perpendicularly and parallel to the plane of the memory layer, of the emission radiation emitted by the individual particles.
