Abstract

A method for improving the image quality of a three-dimensional magnetic resonance image dataset recorded with a magnetic resonance device, wherein, from at least one correction image dataset recorded with a modality other than magnetic resonance imaging, registered with the magnetic resonance image dataset, showing at least partly the same recording region as the magnetic resonance image dataset, especially an x-ray image dataset, relevant material parameters are derived locally-resolved for the magnetic resonance imaging, which are used for establishing a virtual magnetic resonance comparison dataset in a simulation wherein, as a function of a comparison between the magnetic resonance image dataset and the magnetic resonance comparison dataset, at least one measure parameter describing an image quality improvement measure to be applied in the k-space is determined and the image quality improvement measure is carried out with the measure parameter relating to the magnetic resonance image dataset.
