Table 7 Easy-to-operate subjective evaluation standard of the auto-segmentation accuracy

From: A novel specific grading standard study of auto-segmentation of organs at risk in thorax: subjective–objective-combined grading standard

Level Auto-segmentation performance  > 10 slices (percentage to be modified) 3–10 slices (slice number to be modified)  < 3 slices (slice number to be modified)
1 Auto-segmentation is not recommended 20%–100%  > 3 3
2 Many manual modifications are required after auto-segmentation 10%–20% 2–3 2
3 Some manual modifications are required after auto-segmentation 0–10% 1 1
4 Auto-segmentation can completely replace manual delineation 0 0 0
