Fig. 2From: Plan robustness analysis for threshold determination of SGRT-based intrafraction motion control in 3DCRT breast cancer radiation therapyRelative PTV dose coverage for varying patient misalignment for left-sided tumor locality. Individual patient plans, their mean and standard deviation (blue) are marked for the 1DOF case. Shift threshold values, based on dose coverage constraints, marked in red with arrows for the 1DOF and the simultaneous 6DOF case. When threshold values were equivalent to the borders of the evaluated ranges (and thus not a calculated solution), a line instead of an arrow was drawnBack to article page
