Results of the phantom imaging over vials with T ₁ values > 700 ms using the proposed and uniform sampling strategies, where each acquisition was repeated 5 times. The ratio of the standard deviation of the T₁ estimator for each proposed sampling strategy and that of the uniform sampling strategy is reported as "standard deviation (std) with respect to (wrt) uniform." There is a gain in using the proposed point selection strategy, which is significantly different than 1 (P < 0.001). The values match those predicted by theory (P = 0.23).
