Fig.1

Correspondences between the subjective evaluation levels and the Dice similarity coefficients (DSC) of six organs at risk in the thorax. Blue represents the DSC value of each patient, and orange represents the mean DSC corresponding to each subjective evaluation level. The dotted line represents the linear trend line of the mean DSC. Red in (a) represents an outlier. It was observed that the auto-segmentation contour not only contained the Lung accurately, but also contained the empty stomach, which could be quickly deleted. So, this auto-segmentation contour still saved a lot of time compared to manual contour, which could be graded as Level 2
