1. A method for producing at least one two-dimensional magnetic resonance (MR) image, comprising the steps of: operating a magnetic resonance data acquisition unit to acquire a first three-dimensional MR image data set of a predetermined region of a subject, with an initial resolution; operating said magnetic resonance data acquisition unit to acquire a second three-dimensional MR image data set of said predetermined region, with a second resolution that is higher than said first resolution; in a processor, determining at least one layer for at least one two-dimensional MR image using said first three-dimensional MR image data set; and generating said at least one two-dimensional MR image with said layer automatically computed in said processor from said second MR image data set.
