Table 1.

Mean integral dose ID (with standard deviations) delivered to PTV calculated for the group of 10 plans computed with the IMRT, VMAT, CK and HT irradiation techniques. Differences between ID in this group were not statistically significant (ANOVA test, p < 0.05).

Irradiation technique	Mean ID [Gy L]	Std. Dev.
CK	2.89	1.12
VMAT (X-6MV)	2.88	1.11
VMAT (X-20MV)	2.88	1.13
IMRT (X-6MV)	2.84	1.07
IMRT (X-20MV)	2.86	1.09
HT	2.83	1.07
