    摘要: In a method for generation of MR exposures in an MR system, a number of under-sampled MR raw data sets are acquired with non-constant density in k-space. A density compensation is implemented dependent on the geometry of the structure to be depicted. The under-sampled MR raw data sets are translated into a Cartesian coordinate system. Fourier transformation of the translated raw data sets in classical three-dimensional space ensues to generate under-sampled MR images. An averaged MR image is generated on the basis of a number of the under-sampled MR raw data sets. The MR exposures are produced by multiplication of the under-sampled MR images with the averaged MR image.
