摘　　要：利用微型磁共振成像仪制作拉链伪影并研究了消除的基本方法通过解Bloch方程和建立物理模型进行定性分析很好地解释了实验结果，并揭示了“K空间”的物理实质．Zipper Image Artifacts have been created by a device of Micro Magnetic Resonance Imaging. And It has been achieved that how to remove those artifacts. The results of our experiments were thoroughly discussed by qualitatively analysis through solving the Bloch Equations and the establishment of physics models. The physics principle of ＂k＂ Space was revealed for MRI by our studies.

关 键 词：磁共振成像 拉链伪影 BLOCH方程 自旋回波 K空间
