Boxplots of 4DMRI quality parameters for 14 subjects, reconstructed with four binning strategies. Data inclusion (DI), reconstruction completeness (RC), intra-bin variation (IBV), inclusion range (IR) and image smoothness (S). Boxes: median value and lower and higher quartiles; whiskers: lowest and highest data point within 1.5 times the inter-quartile range (IQR) from the quartiles; dots: outliers (outside 1.5 times the IQR from the quartiles), stars: extreme outliers (outside 3 times the IQR from the quartiles). The Min95 technique performed significantly different than each of the other three techniques, except versus MeanIE for RC and S, with α = 0.05
