Clinical Validation and Quantitative Evaluation of a Novel Artificial-Intelligence Automatic Segmentation Tool in Radiotherapy Planning

Abstract

higher than 0.90 for all OARs except the esophagus (mean DSC 0.83 ± 0.09)). Mean DSC values ranged from 0.98 ± 0.01 to 0.83 ± 0.09, while the DTAmean ranged from 0.68 ± 0.3 to 0.84 +0.54 mm to mm. HD values ranged from 9.88±15.99 mm to 25.61±8.78 mm. For all body sites, the AI-AS system was able to generate a full set of contours in approximately 2 minutes, while manual contouring of these structures required approximately 30 minutes.
