MRI Imaging Technology Based on xy Nonlinear Gradient

To eliminate center blurring existing in nonlinear gradient imaging, an imaging technology based on xy nonlinear gradient field was proposed, and the effect of center displacement curve in magnetic resonance imaging (MRI) was discussed. The results reveal that circle center displacement curve with diameter r=1.5 achieves the best reconstruction, and in comparison experiment with O-Space under different acceleration factor R, xy nonlinear magnetic field achieves a better image result.
