The invention relates to a method of acquiring a magnetic resonance image of an object employing spatial encoding by a gradient field, said gradient field comprising non-linear gradient field components, the method comprising: selecting (100) a limited set of spatially variant basis functions for describing the gradient field including the non-linear gradient field components by linear combinations of said basis functions, determining (102) the temporally variant weights of the basis functions for said linear combinations, acquiring (104) magnetic resonance data of the object (10), —embedding (106) the acquired magnetic resonance data into a multidimensional space, wherein the number of dimensions is given by the number of selected basis functions, transforming (110) the acquired magnetic resonance data in this multidimensional space from the measurement domain to the image domain, —calculating (112) the desired magnetic resonance image of the object (10) from this transformed multi-dimensional space by linear combinations along the surplus dimensions. |
