Claim One:
1. A detection values correction apparatus that corrects detection values of a projection image of a multi-energy imaging system comprising a radiation source for emitting radiation for traversing an object and a detection unit having different energy-windows and comprising a detection surface for generating the detection values depending on the radiation after having traversed the object, wherein a detection value represents an intensity, an energy and a location on the detection surface, wherein the detection values correction apparatus comprises: a scatter contribution providing unit that provides scatter contributions produced by radiation running along paths through the object for the different energy-windows of the detection unit for different intensities, different energies and different locations on the detection surface of the detection values, wherein a scatter contribution represents the contribution of the scatter, which is generated by radiation of a detection value representing an intensity, an energy and a location on the detection surface, to the detection value to be corrected, a scatter contributions combining unit that combines scatter contributions for correcting a detection value, wherein the combined scatter contributions represent the contribution of the scatter, which is caused by radiation of the other detection values of the projection image, to the detection value to be corrected and wherein the scatter contributions are combined under consideration of the intensity, energy and location on the detection surface of the other detection values, and a correction unit that scatter corrects the detection value of the projection image by using the combined scatter contributions.
