1. for compensating during nuclear magnetic resonance MRI a method for the motion of region of interest ROI, described side in subjectMethod includes:

  • Select within the first area of-described ROI at least two MRI scout scan of described experimenter predetermined notThe fixing point that affected by the motion of described ROI and select predetermined by described motion within the second area of described ROIThe motor point of impact;

    -during MRI acquisition sequence, identify the motion in described motor point within described ROI;

    -determine described by the motion according to the described motor point identified relative to the described motor point of described fixing point rotationThe motor pattern of described ROI between MRI acquisition sequence;

    And-based on determined by described ROI motor pattern regulation MR image acquisition in visual field FOV to reduce motion artifacts.
