Abstract:
1. A method for operating a magnetic resonance tomography apparatus comprising: acquiring magnetic resonance data from a single RF reception channel of a magnetic resonance tomography apparatus that represent an overview slice image across an entirety of a subject to be examined in a selected slice; in said overview slice image, detecting a marking input of a first image region; in a control unit of said magnetic resonance tomography apparatus, electronically expanding said first image region in at least one phase coding direction, dependent on a geometry of said first image region, said overview slice image and respective positions of said overview slice image and said first image region relative to each other, so as to identify a second image region that is expanded compared to said first image region; with said control unit, operating said magnetic resonance tomography apparatus to acquire oversampled magnetic resonance data in said single RF reception channel from said second image region of said subject, that completely contains said first image region and that is free of foldovers in said first image region; and making said oversampled data accessible from said control unit in a form suitable for reconstructing a magnetic resonance image of said second image region by Fourier transformation.
