Method and device to generate magnetic resonance image data of an examination subject

A magnetic resonance imaging system comprising:

• a magnetic resonance data acquisition unit;
• and
• a reconstruction device comprising a raw data interface in communication with said data acquisition unit, configured to require raw magnetic resonance data in a memory representing k-space, said raw magnetic resonance data comprising measurement values at multiple readout points at which said magnetic resonance data was readout from an examination subject, said multiple readout points being organized in k-space along multiple different trajectories in k-space, a displacement value determination unit having access to k-space in said memory, configured to automatically determine a displacement value for each trajectory among said multiple different trajectories based on measurement values of a collection of said multiple different trajectories, a correction unit configured to displace said readout points of the raw magnetic resonance data in k-space by said displacement value along the respective trajectories, thereby producing displaced raw magnetic resonance data, and a reconstruction unit configured to reconstruct image data of the examination subject based on the displaced raw magnetic resonance data, and making said image data available as a data file at an output of said reconstruction unit.
