Figure 5

(a) Normalized root mean squared error (NRMSE) and (b) mean structural similarity index (MSSIM) between SR reconstructions from different numbers of orthogonal LR HASTE series simulated at a GA of 30 weeks and the corresponding static 3D HR ground truth. The left panel shows results for motion-free data with various noise levels, a SD of 0.15 leading to a similar appearance as in clinical acquisitions. The right panel illustrates how the algorithm performs depending on the amplitude of fetal movements in the input series.
