Abstract: In a method for reading out information stored in a phosphor layer whereby the phosphor layer is stimulated into emitting emission light by stimulation light produced from a light source, the emission light emitted from one or several areas of the phosphor layer is collected by a detector moved relative to the phosphor layer, and then converted into corresponding emission light signals. In order to improve the signal/noise ratio, the light source is momentarily switched off at least once during the movement of the detector relative to the phosphor layer. When the light source is switched off, a background, which is caused by the ambient light and/or dark currents in the detector, is collected by the detector and converted into a corresponding background signal. The background signal is then used for correcting the emission light signals.
