Fig. 6From: Comments on the NEMA NU 4-2008 Standard on Performance Measurement of Small Animal Positron Emission TomographsSimulated recovery coefficient of the 5-mm rod as a function of the uniformity. The ground truth for the recovery was 0.95. The simulated recovery coefficients are always larger than the ground truth and increase with increasing variance (i.e., larger uniformity values)Back to article page
