The measured background and artifact SUL values for the reference and multiple simulated activities. The SULmax, SULmean, SULstd, and SULcov of the background VOIs are shown in a–d, respectively. The SULmax and SULmean of the artifact VOIs are shown in e and f. The horizontal axis indicates the 4-min reference (4 m) and decreasing activity (x%) reconstructions. Results are reported as median ± interquartile range. An asterisk indicates a significant difference with the reference. For the 5% activity, 2 data points in the SULmax graph (a) and 1 data point in the SULstd graph (c) are outside the shown range
