Abstract: In a method for image data acquisition of a region of interest in a subject with a magnetic resonance device, wherein, to establish the field of view, a minimal geometric shape encompassing the subject to be acquired and/or the surface of the subject is determined automatically from previously acquired localizer exposures as aliasing information for each exposure, at least one slice plane is determined for the acquisition of the region, and the phase coding direction and/or the extent of the field of view in the phase coding direction is determined for every slice plane using the aliasing information.
