Magnetic resonance plane echo imaging method based on prospective motion correction

The invention discloses a magnetic resonance plane echo imaging method based on prospective motion correction, and relates to the field of magnetic resonance imaging, the method is realized through a motion tracking system and a plane echo imaging sequence, and the method comprises the following steps: using the motion tracking system to position the initial position and direction of a tested part, and determining the initial position and direction of the tested part; setting a sequence initial scanning positioning parameter; using a motion tracking system to obtain the position and the direction of the tested part before planar echo imaging sequence scanning is started; calculating the displacement and the rotation angle of the tested part relative to the initial position before plane echo imaging sequence scanning is started; according to the displacement and the rotation angle, scanning positioning parameters are updated, so that the scanning view is consistent with the initial scanning view; and performin
