Production of mr - image data with parallel layer excitation and partial overlapping of the layers in the frequency range

摘要

Method for the production of mr - image data of a predetermined volume portion (24) inside of an examination subject (o) by means of a magnetic resonance system (5), including the steps of:simultaneous stimulation of a plurality of layers (s₁–S₈) of the volume portion (24) by means of at least one hf - excitation pulse (25; 26), wherein during of the stimulation is a slice selection gradient (g_Z) is switched,Detection of measurement signals of the plurality of layers (s₁–S₈), wherein the measurement signals with a plurality of hf - receiving antennas (a₁–A₄; A_1,2–A_4,5) be detected, which at least partially along the propagation direction (z) of the slice selection gradient (g_Z) spaced apart and wherein during the acquisition of measurement signals of the slice selection gradient (g_Z) is switched in a partial spectral separation of the measurement signals from different of the layers (s₁–S₈) to achieve, as a result of which a partial overlapping of the layers (s₁–S₈) in the frequency range is reached, andProduction of the mr - image data by means of the measurement signals.
