Measured temporal dose pattern of a voxel element from different IMRT techniques for (a) prostate, 1.8 Gy/fx; (b) prostate, 4.3 Gy/fx; (c) prostate, 7.25 Gy/fx; and (d) head/neck, 2.0 Gy/fx.
Measured dose temporal pattern of helical tomotherapy treatment: (a) Prostate, 1.8 Gy/fx with 2.5 cm field width and (b) prostate, 1.8 Gy/fx with 1.0 cm field width. The solid line is obtained by smooth averaging of the measured data and dashed lines are the fitted results of the averaged data between 0% and 5% and between 20% and 50% of the maximum dose rate. In addition, static beam profiles along the longitudinal direction are also shown as inset in each panel for comparative purposes.

Percentage EAD losses for different head/neck treatment techniques.
(a) Tumor control probability of intermediate risk prostate cancer and laryngeal cancer (reproduced from Refs. 21 and 22). (b) Change in TCP as a function of percentage EAD loss.
