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...
