摘要

The invention relates to a method for the production of mr - images in an mr - system, comprising the steps of: receiving a plurality of under sampled mr - raw data sets at a density in the k - space, performing a density-dependent, wherein the density-dependent correction in dependence on the structure of the anatomy can be selected to be displayed, converting the sub-sampled mr - raw data sets in a cartesian coordinate system, fourier transformation of the converted raw data sets in the local space for the production of sub-sampled mr - images, creating an averaged mr - image on the basis of several sub-sampled mr - raw data etching, and production of the mr - images taken by means of multiplication of the sub-sampled mr - images with the averaged mr - image.
