1. A method to image a partial region of an examination subject in an Imaging system across at least two measurement slices, comprising: positioning an examination subject in a magnetic resonance data acquisition unit, having a field of view, with a partial region of the examination subject, of which a magnetic resonance image is to be obtained, being located at least in part at an edge of said field of view, said data acquisition unit comprising a gradient coil system and a basic field magnet; with a computer system, operating said magnetic resonance data acquisition unit with a data acquisition pulse sequence in order to acquire magnetic resonance data of said partial region in a multi-slice measurement in which a slice selection gradient and a readout gradient are activated by the gradient coil system of the data acquisition unit, that respectively produce a slice selection gradient field and a readout gradient field while a basic magnetic field is generated by the basic field magnet of the magnetic resonance data acquisition unit; operating said magnetic resonance data acquisition unit with said pulse sequence in order to optimize each voxel in said image, that is located at said edge of said field of view, in each of said measurement slices of said partial region, by configuring at least one of said slice selection gradient, or said readout gradient of said pulse sequence, as an at least one configured gradient in said pulse sequence, in order to make a distortion caused by a non-linearity of the respective gradient field of said at least one configured gradient, cancel a distortion caused by a basic magnetic field inhomogeneity of said basic magnetic field that exists at each of said voxels being optimized at said edge of said field of view; and with said computer system, reconstructing an image of said partial region from said acquired magnetic resonance data.
