Abstract

A method for imaging a part region of an examination object in a magnetic resonance system. In an embodiment, a first and second gradient field are respectively created such that, at a respective first and second position at the edge of the field of view, a distortion caused by a non-linearity of the respective first and second gradient field, and a distortion caused by a Bo field inhomogeneity, cancel each other out. By way of the respective first and second gradient, respective first and second magnetic resonance data which contains the respective first and second position are acquired. A first and second respective readout direction, in which the respective first and second magnetic resonance data are acquired, are selected as a function of a location of the respective first and second position. From the magnetic resonance data, an image of the part region is defined.
