Adaptive radiotherapy (ART) is designed to improve target coverage and normal tissue sparing compared with non-ART treatment. While in prostate SBRT differences between adaptive and non-adaptive plans are often modest, certain fractions exhibit clinically sig...
Ethos Version 2 has several new capabilities, including high-fidelity (HF) adaptive planning, AI-based auto-segmentation, and dose calculation using HyperSight CBCT. This study evaluates these new features for online adaptive radiotherapy (ART) for prostate S...
Adaptive radiotherapy (ART) enables daily plan adjustment to account for anatomical changes. Given the high doses and tight margins in prostate SBRT, this study quantifies intrafractional prostate motion and its implications in the PTV margins.
Organ at risk dose limits as a function of varying fractionation scheme are conveniently given in the well-known “Timmerman tables”. Application of these limits in the re-treatment environment using the LQ approach (EQD2) can lead to overestimation of availab...
