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.
