Figure 3: (a) Comparison of planning system-based heterogeneity-corrected PLANAR fluence from electronic portal imaging device in the absence of patient with the planning system calculated individual beam fluence. Gamma analysis (3% DD-3 mm DTA) results for total 85 individual beams for the thorax, pelvis and head-and-neck cases, (b) Quasi-three-dimensional dose verification using gamma analysis.
