Dosimetric-based segmentation list
Lung received 5–60 Gy or higher : Lung ∩ 5–60 Gy
(Lung-GTV) received 5–60 Gy or higher: Lung-GTV ∩ 5–60 Gy
Lung-PTV received 5–60 Gy or higher: Lung-PTV ∩ 5–60 Gy
PTV received 40–60 Gy or higher: PTV ∩ 40–60 Gy
(PTV + 5 mm) received 30–60 Gy or higher: PTV + 5 mm ∩ 30–60 Gy
(PTV + 10 mm) received 20–60 Gy or higher: PTV + 10 mm ∩ 20–60 Gy
(PTV + 20 mm) received 10–60 Gy or higher: PTV + 20 mm ∩ 10–60 Gy

“ROI ∩ XX Gy” indicated the ROI received XX Gy or higher.
