Abstract:
1. An X-ray arrangement for imaging an object under examination that contains at least one opacifying element that comprises a. at least one x-ray radiation source that emits essentially polychromatic x-ray radiation with a continuous spectrum, b. at least one energy-dispersive detector for simultaneously detecting the intensity of x-ray radiation that gets through the object under examination at a given pixel at a first energy E c. at least one correlation unit for correlating the intensity of the detected x-ray radiation from said pixel of the object under examination at said first energy E d. at least one output unit for visualizing the object under examination from the pixel signals obtained by correlation of the intensities, wherein one of the first energy E 1 and the second energy E 2 is above the energy of the K- or L-absorption edge of the opacifying element and the other is below said edge.
