Comparison of the effect of view-sharing reconstruction techniques in regions with large temporal changes (a) Dashed box highlights lung-liver interface where the average rESF was estimated. (b) Mean rESF across breathing phases as a function of reconstruction technique. Normalized value of unity refers to highest spatial resolution. In regions with large temporal changes, RSGR-PEVS provides a significant improvement in spatial resolution while ESP-PEVS degrades spatial resolution. Bar-plots depict average ± standard error of mean. (c) Displacement of lung-liver interface determined from ten line profiles at the region highlighted in panel (a). The effect of view-sharing is shown for the stack-of-stars trajectory. See Supplementary Figure S5 for the multidimensional golden means trajectory.
