Figure 6: The depth dose curves for radiation emitted from flattening filter free linac measured and calculated by Monte Carlo simulation in 30 cm×30 cm field. Green line shows the measured depth dose for 10 MV flattening filter free beam without metal filter. Black line shows that with 2 mm thick copper filter. Red dash line shows that with 5 mm thick aluminum filter.
