Abstract: A method for the X-ray inspection of products of a predefined product type including at least one first component and one second component having different absorption coefficients for X-radiation. X-radiation with a spectral range is transmitted through a product to be examined. The X-radiation that has passed through the product is detected by means of a spectrally resolving X-ray detector. The spectrally resolving X-ray detector assigns the X-ray quanta to a number of energy channels and generates image data which for each pixel include spectral values for selected or all energy channels and/or total spectral values for one or more groups of adjacent energy channels. At least one mapping rule is used to process the image data to form a total image, where each mapping rule is designed such that spectral values or total spectral values are mapped onto a total image value of an image point.
