Accelerated partial breast irradiation (APBI) combined with online adaptive radiotherapy (OART) offers precise treatment of early-stage breast cancer, but inter-observer variability (IOV) in target delineation must be accounted for to maintain treatment quali...

Common contour evaluation metrics(e.g., DSC or HD) provide global summaries that can miss localized, anisotropic disagreements that drive clinically meaningful edits. Although surface-DSC(SDSC) better reflects boundary discrepancies, it typically uses a subje...
Minor and major errors may occur in both manual and automatic organ contouring process, such as mis-localization or severe under/over-segmentation. They can subsequently impact the accuracy of dose optimization and planning. This study aims to develop an auto...
Deep-learning (DL) auto-segmentation is routinely used clinically, yet domain shift and vendor model upgrades can change behavior in non-intuitive ways. We present a regression-testing framework to commission upgraded commercial auto-contouring models and to...
