    Abstract: A method for providing information about a spatial gain distribution of a scintillator for a primary radiation is provided which does not require the irradiation of the scintillator with the primary radiation. The method comprises the step of irradiating the scintillator with a secondary radiation for generating an image of a spatial secondary gain distribution of the scintillator for said second radiation. The spatial secondary gain distribution image corresponds to an image of the spatial primary gain distribution for the primary radiation. In an embodiment of the invention, i.e. in an X-rayimaging device where the primary radiation is X-rayradiation, the invention provides for an accurate calibration of the X-raydetector without irradiating the X-raydetector with X- rayradiation. Rather, irradiation with UV radiation as the secondary radiation provides the desired spatial secondary gain distribution image which can be used for calibration.
