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...
The MIRAGE trial demonstrated reduced acute toxicity in intact prostate radiotherapy in MRI arm, partially attributed to the use of smaller PTV margins (2 mm versus 4 mm with CT guidance). Motivated by these findings, this study retrospectively evaluates whet...
