Crossbeam profiles in the air cylinder phantom for a $10\times 10\hspace{0.17em}{\text{cm}}^2$ applicator at 12 MeV and $\text{SSD}=100\hspace{0.17em}\text{cm}$: (a) profile at the air cylinder–plastic water interface (2.7 cm of depth); (b) profiles in plastic water at two different depths (4.2 cm and 6.3 cm); (c) PWDT‐corrected profiles in plastic water (4.2 cm and 6.3 cm).
