Abstract
A CT system is disclosed for phase-contrast and absorption imaging with a plurality of emitter-detector systems. In at least one embodiment, there are at least two emitter-detector systems and the at least two emitter-detector systems have a different distance between radiation focus and detector and there is a computational element for calculating phase-contrast images on the basis of the solution to the intensity transport equation. Moreover, at least one embodiment of the invention relates to a method for phase-contrast and absorption imaging using such a CT system by comparing attenuation images recorded at different distances of a detector from a multiplicity of projection angles by solving the intensity transport equation and reconstruction or comparison of two tomographic and three-dimensional image data records, reconstructed from projections, which were recorded at different distances.
