图1. (a)鞍型、(b)亥姆霍兹、(c)螺线管线圈在感兴趣圆柱体区域的B1场分布.其中：磁通密度指感兴趣圆柱体内各位置的磁感应强度，圆柱体内颜色由蓝到红表示磁感应强度由弱到强.螺线管和亥姆霍兹线圈磁场方向沿z方向，鞍型线圈磁场方向沿x方向
Fig. 1. The B1 field distribution of the saddle (a), Helmholtz (b) and solenoidal (c) coils in the cylindrical region of interest, respectively. Where: Magnetic flux density refers to the magnetic induction strength at each location within the cylinder of interest, with the colours within the cylinder ranging from blue to red indicating weak to strong magnetic induction. The magnetic field direction is along the z-direction for solenoids and Helmholtz coils, and along the x-direction for saddle coils
