Table 2.

The result of the 3D gamma analysis on both the ranged-corrected approximation and static dose approximation with respect to the full dose (TPS) calculation under setup error and weekly CT simulations. A passing criterion of 3% dose difference and 3mm distance-to-distance agreement was used. For the sake of simplicity, for both prostate and HN cases, only the worst passing rate observed during weekly simulation is shown (week1 for prostate and week6 for HN).
