Table 2.

Dose differences between all predicted plan groups and benchmark plans.

Plan type	Dose type	Region	Voxel dose difference [%]	Dmean difference [%]	Dmax difference [%]
FD-CNN dose	Total dose (CNN)	ROI	1.79 ± 2.21	0.41 ± 0.28	0.48 ± 0.31
		PTV	0.91 ± 0.79	0.57 ± 0.25	0.48 ± 0.31
		ROI–PTV	2.65 ± 2.75	0.51 ± 0.34	0.49 ± 0.54
	Field dose (CNN)	ROI	1.25 ± 1.11	0.51 ± 0.42	1.82 ± 1.44
FM-CNN plan	Total dose (TPS)	PTV	1.22 ± 0.96	0.88 ± 0.65	1.46 ± 1.19
		OAR	0.86 ± 0.75	0.30 ± 0.17	0.86 ± 0.52
Model-predicted plan	Total dose (TPS)	PTV	2.41 ± 1.87	1.24 ± 0.74	4.10 ± 2.35
		OAR	2.70 ± 2.45	0.94 ± 0.65	4.77 ± 2.84

Model-predicted plans exhibit larger dose differences than FD-CNN doses and FM-CNN plans.
