Fig. 6.

The number of dynamic multileaf collimator (DMLC) fields with an observed $\stackrel{‒}{\gamma }$ for Analytic 1, Analytic 2, and the hybrid methods. Data were binned into 0.025 intervals for plotting purposes. The top panel is for gamma acceptance criteria of 2% /2 mm, while the bottom panel is for acceptance criteria of 3% /3 mm. With an increase in the rigor of the MLC modeling by the analytic methods, the difference between the analytic and Monte Carlo modeling of the MLC decreases.
