Table 3.

Dose gradient using CI and ${\text{TV}}_{\text{RI}}/\text{TV}$ for FO and DMPO plans and treatments. Differences are calculated between DMPO and FO treatments and their respective plans. Gradient values closer to 1 indicate steeper dose gradients within the dose distribution.

Gradient	DMPO Plan	DMPO‐4	DMPO Difference	FO plan	FO‐4	FO Difference
${\text{CI}}_{90}/{\text{CI}}_{100}$	2.23	2.92	0.69	1.77	2.94	1.17
${\text{CI}}_{95}/{\text{CI}}_{100}$	1.35	1.72	0.37	1.26	1.70	0.44
${\text{TV}}_{90}/\text{TV}/{\text{TV}}_{100}/\text{TV}$	1.13	1.36	0.23	1.07	1.35	0.28
${\text{TV}}_{95}/\text{TV}/{\text{TV}}_{100}/\text{TV}$	1.12	1.27	0.15	1.07	1.26	0.19
