1. A method for actuating a magnetic resonance (MR) device according to an MR control sequence comprising:
at least one excitation pulse followed by at least two consecutive refocusing pulses, wherein, between exactly two of the at least two consecutive refocusing pulses, all magnetic field gradients acting on a readout axis of the readout gradient induce a first Maxwell phase and at least one readout gradient is provided; and
a bipolar gradient pulse having a first part and a second part of opposite polarity arranged between the excitation pulse and a first of the at least two consecutive refocusing pulses, wherein a Maxwell phase induced by the bipolar gradient pulse corresponds to between 40% and 60% of the first Maxwell phase, a gradient moment of the bipolar gradient pulse corresponds to a dephasing gradient moment for the readout gradient, and a duration of the bipolar gradient pulse corresponds at most to a first time interval between the excitation pulse and a first of the at least two consecutive refocusing pulses.
