Figure 6From: Testing the portal imager GLAaS algorithm for machine quality assuranceExamples of mechanical wedges verification showing Gamma Evaluation matrices (DTA = 3 mm, ΔD = 3%) and profiles in the wedge direction for 15, 30, 45, and 60° wedges on a 10 × 10 cm2 field. Data are reported for Eclipse calculation (blue dashed), GLAaS (red line), and ion chamber (black dots).Back to article page
