图3 (a)和(b)分别表示实验中使用的翻转角和重复时间模式. (c)、(d)、(e)分别展示了实验中在一个重复时间内使用的螺旋欠采样轨迹、伪径向笛卡尔采样掩模以及变密度螺旋欠采样轨迹

Fig. 3 (a) and (b) are the flip angles and repetition time patterns that were used in the experiment. (c), (d), (e) shows the spiral undersampling trajectory, pseudo radial Cartesian sampling mask, and the variable density spiral undersampling trajectory, respectively, used in one repetition time in the experiments
