The correlation between the proposed organ feature and ipsilateral lung V20
isodose
The proposed organ feature that was calculated by the automatically detected marker correlated with ipsilateral lung V20 (Pearson correlation coefficient, 0.542 with As for the proposed organ feature that was calculated by the manually labeled lead wire marker, a similar result can be found (Pearson correlation coefficient was 0.560 with The correlation between the proposed organ feature and ipsilateral lung V20Lung segmentation, lead wire marker detection results and radiation dose distribution. The blue mask was the automatic segmented ipsilateral lung region, the red points were the manually annotated lead wire marker, and the green points were the lead wire marker detected by the proposed DL model. The green area represented the planning target volume. The red line and blue line represented 50 Gy and 20 Gy isodose line, respectively.
