Web(A) Boxplot of Dice similarity coefficient (DSC), 95% Hausdorff distance (HD95), and average surface distance (ASD) for the comparison of manual contours of four radiation oncologists with our treatment planning CT (pCT)-based deep model-predicted contours. Dotted lines indicate the median DSC, HD95, and ASD of our pCT model performance. WebDice= E( ln(DC) Dice) (20) L cross= E(w l( ln(p)) cross)) (21) Wong et al. [16] have used cross= Dice for simplicity. L. Distance map derived loss penalty term Distance Maps can be defined as distance (euclidean, ab-solute, etc.) between the ground truth and the predicted map. There are two ways to incorporate distance maps, either create
WebDice-coefficient and Hausdorff distance showed good agreement between manual and automatic segmentations (≥ 0.89 and ≤ 10.6 mm, respectively) which further improved after simulated correction of the most basal slice (≥ 0.92 and ≤ 9.2 mm, p < 0.001). WebAgreement between segmentations on T2w-images between urologists and radiologists was assessed with Dice similarity coefficient (DSC) and 95 % Hausdorff distance (95 % HD).
