FIG. 5.

Reconstructed 10-bin T2-weighted 4D-MRI (only phase 5 is shown as a representative) simulated with XCAT phantom in axial (a), sagittal (d), and coronal (g) view, in comparison with the original 4D XCAT images [(b), (e), and (h)]. The differences between the two are shown in panels (c), (f), and (i) respectively. This is the XCAT simulation results where breathing motion was strictly regular and the data sufficiency condition was met. The total number of repetition (N_R) was set as 30 for the simulation scan.
