Assessment of PTV Margins for Unity MR-Linac Treatments Using Cine-MRI Target Motion
In comprehensive motion management (CMM), Elekta Unity MR-Linac uses cine-MRI to monitor intra-fraction target motion. Due to the lack of efficient tools to determine patient-specific treatment margin, an isotropic GTV-to-PTV margin of 5 mm is used for all li...

Deep Learning-Based Estimation of Minimal Editing Margins for Online Adaptive MR-Linac Prostate SIB
Online adaptive prostate SIB treatment on the Unity MR-Linac is challenged by the limited robustness of deformable image registration (DIR)-based contour propagation. This study investigates the use of a deep learning (DL) dose prediction model to guide the d...

Rapid and Explainable Dibh Patient Selection Using Fully Automated, Planning-Free Deep Learning Framework In Left-Sided Whole-Breast Radiotherapy
Simple clinical criteria for deep inspiration breath-hold (DIBH) eligibility in left-sided whole-breast radiotherapy, such as the ability to sustain a 20-30 second breath-hold, are commonly used but do not reliably predict dosimetric benefit. Robust assessmen...
