Figure 4

Contrast recovery for the six spheres in the NEMA IEC Body Phantom. The plotted data are mean values from three repeated acquisitions. The error bars on each data point represent standard errors on the mean. In almost all cases, contrast recoveries for no motion are not significantly different from those for motion with respiratory gating (data-driven (DDG) or externally driven (RPM)). Application of motion without gating led to significantly lower contrast recoveries (all p < 0.05). DDG, data-driven gating; RPM, Real-time Position Management system.
