Abstract
A method for operating a nuclear magnetic resonance imaging device, wherein a continuous sequence of radio-frequency (=RF) pulses are radiated onto a sample, Ψ being the constant phase value for all magnetization vectors, and all magnetization vectors undergo a phase progression F=nΨ during the n-th sequence interval, wherein P is the number of RF pulses after which the phase angle of the magnetization vectors is repeated, wherein the total gradient moment in one or more directions in space having a value greater than 0, and consecutive pulses exhibit a constant repetition time TR, wherein, after radiation of one RF pulse, one k-space row is acquired. The method is characterized in that any one- or multi-dimensional arrangement of k-space rows is repeated identically N times, and signals from identical k-space rows are averaged or added. The method increases the efficiency of the gradient spoiling and thus the efficiency of artifact suppression.
