The ability to monitor and manage target motion in real time is rapidly becoming a cornerstone of precision radiation therapy. As institutions expand adaptive treatment programs, hypofractionation, and tighter margins, the clinical demand for robust motion ma...

Patient coaching on the Elekta Unity MR-Linac is challenged by an enclosed bore that limits direct observation and by high acoustic noise during MR imaging that can reduce comprehension of verbal commands. We developed a synchronized, dual-interface visual co...

Combination radiopharmaceutical therapy (RPT) and external beam radiation therapy (EBRT) is an underexplored strategy that may improve outcomes over either modality alone; however, practical implementation requires a clear understanding of dosimetry and radia...

Weisskoff analysis assesses temporal stability of echo-planar imaging (EPI) in functional MRI (fMRI) by comparing how the temporal coefficient of variation (CoV) scales with ROI size relative to uncorrelated noise (e.g. ideal scaling) to assess unwanted inter...

Online adaptive prostate MR-guided radiotherapy (MRgRT) is time-sensitive, and contouring with structure preparation can require upwards of 15 minutes per fraction. While vendor-TPS provided contours can be useful, performance and consistency vary by site, pr...

Magnetic resonance imaging-guided online adaptive radiotherapy (MRgRT) requires a complex planning process, during which an upstream peer review prior to physician approval plays an essential role in early error detection and supporting safe and efficient onl...

To compare MR-simulation motion emulation with measured respiratory gating performance for ultra-central lung treatments on 1.5T MR-linac and to identify the dominant factors affecting gating efficiency. The study focuses on the role of tracking surrogate sel...

MRI-based intrafraction motion management is increasingly used during MR-guided adaptive radiotherapy, yet limited data exist on its real-world performance and limitations across disease sites. This study reports institutional experience with Comprehensive Mo...
