Patent ID: 8542795

Claim:
A method for obtaining high-contrast X-ray images with the aid of an X-ray beam detector, which has an arrangement of light-sensitive detector elements beneath a scintillator layer, wherein each detector element provides a grayscale value in a pixel arrangement for defining an X-ray image, comprising the following steps: obtaining a test X-ray image of a predetermined object with the aid of the X-ray beam detector, deriving at least one mathematical variable or at least one function of a variable from the test X-ray image, which variable, under the assumption that the generation and scattering of light in the scintillator layer is understood as a convolution of an input signal of the incident X-ray radiation with a transfer function, provides information relating to the transfer function, obtaining a raw X-ray image of an object to be imaged with the aid of the X-ray beam detector, and processing the raw X-ray image using the at least one variable or the at least one function in order to remove, at least in part, an effect on the image contrast by the light propagation within the scintillator layer.
