Patent Images

1. a method for distortion calibration in magnetic resonance imaging, is characterized in that, comprising:

  • Plurality of data readout direction gathers K space data, and the sampled point on phase encoding line concentrates on low frequency region and its quantity is less than the quantity of full sampled point, and on slice selective gradient axle, superpose the compensation gradient of visual angle inclination;

    The described K space data gathered from a plurality of direction is combined, and is converted to final image.
