Table 5. The volume of GTV evenly expanded by 1 and 2 mm and the % coverage with the minimum dose to cover the volume minus 0.01 or 0.035 cc.

*The volumes (GTV + 1 mm, GTV + 2 mm) were generated using the MIM Maestro software. The volumes vary depending on the system algorithm used, even for the same GTV

The coverages of the GTV + 1 and 2 mm by the minimum dose that covers the volume subtracted by 0.01 and 0.035 cc from the GTV + 1 mm and 2 mm

GTV: gross tumor volume; D_{V-0.01 cc}: a minimum dose to cover a target volume minus 0.01 cc; D_{V-0.035 cc}: a minimum dose to cover a target volume minus 0.035 cc

GTV (cc)	1.00	2.50	5.00	7.50	10.00	12.50	15.00
GTV + 1 mm (cc)*	1.52	3.43	6.43	9.35	12.25	15.05	17.91
Coverage (%) of GTV + 1 mm for DV-0.01 cc	99.35	99.71	99.85	99.89	99.92	99.93	99.94
Coverage (%) of GTV + 1 mm for DV-0.035 cc	97.70	98.98	99.46	99.63	99.71	99.77	99.80
GTV + 2 mm (cc)*	2.29	4.71	8.37	11.80	15.15	18.43	21.60
Coverage (%) of GTV + 2 mm for DV-0.01 cc	99.56	99.79	99.88	99.92	99.93	99.95	99.95
Coverage (%) of GTV + 2 mm for DV-0.035 cc	98.47	99.26	99.58	99.70	99.77	99.81	99.84
