A device and a method for reading out information stored in a storage layer (), and an X-ray cassette are proposed which make use for the purpose of erasing information stored in the storage layer () of an erasing means () which generates an erasure radiation (). This erasure radiation () can have both a first and a second intensity, the first intensity being larger than the second intensity.

Device and method for reading out information stored in a storage layer, and x-ray cartridge

The invention relates to a storage layer () for storing x-ray information, comprising a large number of needle-shaped storage material areas (A toL) for guiding light radiation (toto). An absorption zone (A toN), which contains absorption material for absorbing light radiation (toto) lies between the individual needle-shaped storage material areas (A toL) and absorbs less than all of the light radiation that it receives. The invention also relates to a device for reading x-ray information from a storage layer of this type and to an x-ray cassette which has a device of this type for reading x-ray information.

Storage layer, conversion layer and a device for reading x-ray information, in addition to an x-ray cassette

Apparatus for reading information stored in a memory layer ( ) which includes a shielding device ( ), and an X-ray cassette and an X-ray table for use with the apparatus, are disclosed. The shielding device ( ) serves to shield a reader device ( ) from an information recording beam ( ). The reader device ( ) includes a receptor ( ) to receive emission radiation ( ) that contains an image of the information recorded in the memory layer ( ). Instead of the shielding device ( ), it is also possible to provide a converter ( ) that serves to convert an information-recording beam ( ) into converted radiation ( ) that possesses less energy than the information recording beam ( ).
