Figure 2: Schematic of DLG measurement using ionization chamber. (A) Gantry (B) MLC (C) Direction of sweeping beam. The magnified image shows the dose being delivered at different instances of the sweeping beam. A uniform dose (portrayed by the flat profile) is achieved as the result of the integrated dose. (D) Radiation field analyzer (E) Parallel orientation of ionization chamber (with respect to the direction of sweeping beam)
