Table 6 Subsampling: Mean values and standard deviations, determined in 12 ROIs (ascending, top, descending with inner radius, outer radius, anterior radius, posterior radius, respectively) over 5 individual reconstructions in a representative mouse (mouse 4 in Table 1). Each 4D flow image was reconstructed from 6 subsets (reconstruction 1: subsets 1–6. reconstruction 2: subsets 2–7
