1. A method for avoiding artifacts during the acquisition of magnetic resonance (MR) data of an examination object, the method comprising:
controlling a MR scanner to acquire, segment-wise in a readout direction, a first measurement data set of a target region of the examination object, wherein the first measurement data set excludes a sample of a first region of k-space sampleable according to Nyquist and corresponding to a first partial factor;
controlling the MR scanner to acquire, segment-wise in the readout direction, a second measurement data set of the target region of the examination object, the second measurement data set excluding a sample of a second region of k-space sampleable according to Nyquist and corresponding to a second partial factor, and the first region and the second region each include at least one segment of the segment-wise acquisition, wherein the first region and the second region are different from each other; and
creating a combined measurement data set based on the acquired first and second measurement data sets.
