Table 5.

Comparison in passing rates (%) between iPlan MC‐calculated and MatriXX dose distributions without and with “central correction” or “entire correction” for various simple plans in a $10\times 10\hspace{0.17em}{\text{cm}}^2$ field of 6 MV photons. Gamma evaluation was performed with 2% dose difference and 2 mm DTA, and 3% dose difference and 3 mm DTA.
