Figure 2From: Optimal set of grid size and angular increment for practical dose calculation using the dynamic conformal arc technique: a systematic evaluation of the dosimetric effects in lung stereotactic body radiation therapyDose–volume histograms for grid sizes of 2 mm, 3 mm, and 4 mm in the plan for S 2 . Each plan was optimized to fully cover 95% of the planning target volume with the prescribed dose.Back to article page
