1. An apparatus for motion correction in magnetic resonance imaging, the apparatus comprising:
processing circuitry configured to
compare first data from a first section of k-space and second data from a second section of the k-space to determine consistency for the second section of the k-space, the first section of the k-space being at least one shot selected from a plurality of shots of the k-space of the magnetic resonance imaging, the second section of the k-space being at least one other shot of the plurality of shots of the k-space,
combine the first data from the first section of the k-space with the second data from the second section of the k-space when the consistency is acceptable, while not using the second data from the second section of the k-space when the consistency is not acceptable, to generate combined data of the k-space, and
perform reconstruction process including motion correction process to generate a final image, based on the combined data of the k-space.
