FIGURE 8.

(A) The image RMSEs of the temporal‐variant CAIPI sampling with all different shifts between odd and even echo‐sections are calculated. The block size is 12 × 6 (k_y × k_z), so the shift range of k_y is 0‐12 (0 and 12 are the same), and the shift range of k_z is 0‐6 (0 and 6 are the same). Two different patterns are selected to illustrate the factor that affects the performance at different shifts. The sampling pattern of odd echo‐section, even echo‐section and the total pattern are shown in Figure 8B,C for Pattern 1 (4‐1 shift) and Pattern 2 (12‐0). Pattern 2 shows more complementary sampling in the k_y‐k_z block than Pattern 1, and achieved lower RMSE of the reconstructed image
