Patent ID: 8629419

Claim:
A method for reading out X-ray information stored in a storage phosphor plate, comprising: irradiating the storage phosphor plate with stimulation light and so being stimulated into emitting emission light; collecting the emission light with a detector during several emission measuring times where the emission light is converted into corresponding emission light signals; during several reference measuring times, taking measurements by the detector of reference light generated by a reference light source and producing several reference signals, wherein the individual reference measuring times fall respectively between the emission measuring times; using the reference signals to examine the sensitivity of the detector to emission light; and the detector producing several offset signals during several offset measuring times in which (1) there is no irradiation of the storage phosphor plate with stimulation light and (2) the reference light source is off, from the several offset signals at least one offset value being derived which is a measure for a background which is caused by background light and/or dark currents of the detector and is used for correcting the emission light signals, wherein the individual reference measuring times and offset measuring times fall between the emission measuring times following on from one another alternately and being separated from one another by at least one measuring time respectively.
