Abstract
To increase the contrast in the imaging in an object under examination that contains at least one radiopaque element, an arrangement that has the following features is used: a) at least one essentially polychromatic x-ray radiation source that emits x-ray radiation, b) at least one energy-dispersive detector, with which the intensity of the x-ray radiation that gets through the object under examination is detectable, c) at least one correlation unit, with which the intensity of the detected x-ray radiation from a pixel of the object under examination with a first energy Ecan be correlated with the intensity of the detected x-ray radiation from the same pixel with a second energy E, d) at least one output unit for visualizing the object under examination from the pixel signals that are obtained by correlation of the intensities.
