Fig. 5. — Relationships between the absolute dose difference and the potential error (PE) value (a) and dose heterogeneity (b). The horizontal axis represents the PE value (a) and dose heterogeneity (b), and the vertical axis represents the absolute dose differences (in percentages) between the measured and MultiPlan-calculated doses. The yellow arrow in Fig. 5b indicates an outlier with a small dose heterogeneity and a large dose difference (a detailed dose distribution of this case is provided in the Discussion). SPE: group with smaller potential errors; LPE: group with larger potential errors.
