Feasibility and Benefit of Reduced CTV-to-PTV Margins In Prostate VMAT Using Monte Carlo–Based Geometric Perturbation
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...
