Abstract
A method for image reconstruction is disclosed, based upon a first plurality of spectral raw data sets. The method includes forming a second plurality of virtual raw data sets; reconstructing an auxiliary image data set on the basis of a virtual raw data set. A first material is selected from a material group which comprises a plurality of materials. Material-specific maps are generated for a number of second materials of the material group. A determination of material line integrals take place, for the second materials with forward projection of the respective material-specific map. Subsequently, synthetic projection data sets are determined for each material. Finally, a reconstruction of at least one image data set takes place on the basis of the synthetic projection data sets for a number of materials of the material group. An image reconstruction device and a computed tomography system are also disclosed.
