The invention relates to an apparatus for capturing information contained in a phosphor layer, comprising an irradiation device () for irradiating the phosphor layer () with stimulation light () which is adapted to stimulate emission light () in the phosphor layer (), the irradiation device () including with the normal (L) on the phosphor () layer a first angle of inclination (&#x3b1;), and comprising a detection device () for capturing emission light () stimulated in the phosphor layer (), the detection device () including with the normal (L) on the phosphor layer () a second angle of inclination (&#x3b1;). To reduce losses of intensity and definition it is provided according to the invention that the first angle of inclination (&#x3b1;) of the irradiation device () and the second angle of inclination (&#x3b1;) of the detection device () are selected such that components of the stimulation light () reflected by the phosphor layer () and then by the detection device () impinge on zones () of the phosphor layer () in which emission light () has already been stimulated.

Apparatus for capturing information contained in a phosphor layer

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.
