摘要： In a method for magnetic resonance imaging on the basis of a partially-parallel acquisition (PPA) reconstruction method and a magnetic resonance tomography apparatus, data for at least two two-dimensional slices of a patient are acquired (which two-dimensional slices are displaced in the direction of a slice-selection gradient (z-gradients) defining the slice-normal direction) with at least one data acquisition in k-space (which acquisition forms a partial data set) per slice with a number of component coils, with the sum of all partial data sets forming a complete data set in k-space. The coil sensitivities of each component coil are determined on the basis of the complete data set. At least one partial data set of each slice is completed with a PPA reconstruction method on the basis of the determined coil sensitivities. The completed slices in k-space are transformed into whole images in the spatial domain.

摘要： In a method and apparatus for MRT imaging, data sets acquired from magnetic resonance signals of at least two limited spatial regions of a subject to be examined, (the spatial regions being displaced relative to one another along one spatial direction and overlapping in the respective edge region. Phase coding occurs in an inhomogeneous non-edge region, likewise in this spatial direction. For at least one of these spatial regions, a modulation function is determined that is limited to this entire spatial region and modulates the subject information. Foldovers in the overlap regions of the different spatial regions are calculated on the basis of the modulation function and the MRT images of the non-edge regions of the respective spatial regions are combined without foldovers in the spatial direction under consideration of the calculated foldings.
