Automatic contours for organs-at-risk predicted by SegNet. Parts a–c are the upper, middle, and lower three-dimensional sections, respectively. The lemon green and lemon yellow areas indicate the automatic bowel bag contours and the manual annotation, respectively. The blue and red areas denote the automatic bladder contours and the corresponding labels, respectively. The dark green and dark yellow areas indicate the automatic contours for the left and the right femoral head and the labels, respectively. The purple and the violet blue contours indicate the automatic rectum results and the manual annotations, respectively. The quantitative DSC results for the bladder, rectum, bowel bag, and left and right femoral head were 0.96, 0.90, 0.90, 0.94, and 0.93, respectively
