摘要

The present invention relates to a method for reducing artifacts in pictures of collects magnetic resonance data of an examination region of an object to be examined by means of a magnetic resonance apparatus, comprising the steps of:– Receiving a first magnet resonance image by means of a first polarization of a high-frequency field of the magnetic resonance apparatus, the amplitudes and / or phases of coil elements of the magnetic resonance apparatus will be described,– Purpose of accommodating at least one further magnet resonance image by means of at least a further polarization of the high-frequency field of the magnetic resonance apparatus, the amplitudes and / or phases of the coil elements of the magnetic resonance apparatus are described, wherein the at least one further polarization of the first polarization and– Combining of image information of the first and at least one additional magnet resonance image.In an advantageous embodiment comprises the combination of the image information of the first and at least one additional magnet resonance image of a use of at least one high frequency magnetic field card and the receptacle of the first magnet resonance image and / or receiving the at least one further magnet resonance image takes place with the sub-sampling.
