Data included (DI); percentage of images remaining after outlier rejection.
Reconstruction completeness (RC); percentage of bin-slice combinations containing at least one image after binning.
Intra-bin variation (IBV); interquartile range of the diaphragm position within the bin-slice combination, averaged over three central slices and ten respiratory bins.
Image smoothness (S); quantified by fitting a parabola to the diaphragm profile in a sagittal plane of the reconstructed 4DMRI.
