Claim:
1. A method for magnetic resonance (MR) imaging for imaging an imaging area of an object, wherein a reconstruction image quality depends on a spatial distribution of background phase, the method comprising the steps of: a) determining a background phase distribution using an optimization algorithm having a reconstruction quality as an optimization criterion, wherein limitation of a spatial variation of a background phase offset distribution is integrated as a boundary condition in the optimization algorithm; b) applying at least one spatially selective radio frequency pulse, said at least one spatially selective radio frequency pulse contributing to generation of an MR signal distribution having a previously determined background phase distribution, wherein the at least one spatially selective radio frequency pulse generates the background phase offset distribution as a part of the background phase distribution; c) acquiring MR signals; d) reconstructing a spatial MR signal distribution; and e) storing and/or displaying an MR image.
