1. A method for controlling a magnetic resonance imaging (MRI) system to generate magnetic resonance image data of an examination subject, the method comprising:
performing an accelerated echoplanar imaging with an undersampling according to a pulse sequence diagram to acquire k-space data, wherein the pulse sequence diagram has a plurality of repetitions which respectively comprise:
a first sampling diagram configured for an acquisition of k-space data for Nyquist ghost correction, or to generate magnetic field maps,
a subsequent second sampling diagram configured for an accelerated echoplanar acquisition, and
an excitation diagram that is common to both the acquisition of the k-space data and the accelerated echoplanar acquisition, wherein the first sampling diagram of a real subset of the plurality of repetitions is modified such that, based on the k-space data acquired according to the modified first sampling diagrams:
k-space data missing due the undersampling is supplemented, and/or
artifacts due to the undersampling in image space are corrected.
