X-ray arrangement and x-ray contrast process for imaging an object under examination that contains at least one radiopaque element as well as use of the x-ray arrangement
First Claim
1. X-ray arrangement for imaging an object under examination that contains at least one radiopaque element that comprises a. At least one x-ray radiation source that emits essentially polychromatic x-ray radiation, b. At least one energy-dispersive detector, with which the intensity of x-ray radiation that gets through the object under examination can be detected, 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 E1 can be correlated with the intensity of the detected x-ray radiation of the same pixel with a second energy E2, d. At least one output unit for visualizing the object under examination from the pixel signals obtained by correlation of the intensities.

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 E1 can be correlated with the intensity of the detected x-ray radiation from the same pixel with a second energy E2, d) at least one output unit for visualizing the object under examination from the pixel signals that are obtained by correlation of the intensities.
