Abstract
A method for magnetic resonance (MR) for imaging an imaging area of an object has a reconstruction image quality which depends on a spatial distribution of background phase. A background phase distribution is initially determined 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. At least one spatially selective radio frequency pulse is applied which contributes 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. In this fashion, the reconstruction quality is improved in a manner which can be realized using available equipment.
