A method is for imaging of an examination region of an object to be examined with a computed tomography system. In an embodiment, the method includes recording of first and second projection measurement data with a common x-ray source-detector system, the first projection measurement data being recorded with a first x-ray spectrum in a first angular sector and the second projection measurement data being recorded with a second x-ray spectrum in a second angular sector; Creation of first and second start image data from the first and second projection measurement data via a first reconstruction method; and coupled iterative reconstruction of first result image data on the basis of the first start image data and of second result image data on the basis of the second start image data, the first result image data and the second result image data each featuring a complete image of the examination region.
