Patent ID: 8278637

Claim:
A process for reading out and erasing X-ray information stored in storage phosphor layers, comprising: reading out X-ray information stored in a storage phosphor layer by irradiating the storage phosphor layer with stimulation light, by means of which the storage phosphor layer is stimulated to emit emission light, and collecting the emission light emitted at different locations (x, y) of the storage phosphor layer with a detector, corresponding detector signal values (D(x, y)) being obtained; and erasing X-ray information remaining in the storage phosphor layer by irradiating the storage phosphor layer with erasing light, the quantity of erasing light with which the storage phosphor layer is irradiated being determined by comparing the detector signal values (D(x, y)) obtained for different locations (x, y) in a first and second dimension (x and y) of the storage phosphor layer to comparison signal values specified for different locations in just one dimension of the storage phosphor layer.
