Figure 1.
In (a), the Monte Carlo simulation results for the normalized PDD curves of the dose and Cherenkov light emission, normalized at depths of 25, 50, 75, 100, 125, 150, 175, and 200 mm are plotted. In (b), the x-ray fluence spectra at depths of 0, 50, 100, 150, 200, 250, 300, 350, and 400 mm are plotted. Both graphs are for a 10 × 10 cm 6 MV beam.
