The underlying mechanisms of radiation-induced lymphocyte depletion are not fully understood. Our goal is to determine if the observed depletion in circulating lymphocytes after radiotherapy is solely due to cell kill, or if changes in cell migration dynamics...

Stereotactic arrhythmia radiotherapy (STAR) is a promising noninvasive treatment for cardiac arrhythmias. Traditional motion expansion PTVs are well-suited to oncology but little is known about their use for STAR. We propose and evaluate a novel myocardial ta...

VMAT total body irradiation (TBI) planning is complex and time-intensive, involving multiple isocenters, junction management, and iterative hotspot control. Many automation approaches still require repeated user interaction, limiting efficiency gains. This wo...

Physics plan and chart review is one of the most effective QA processes to identify high-severity errors in radiotherapy treatments; mastering it is crucial for our residents. However, exposure to such errors during training is limited, making it challenging...

Stereotactic arrhythmia radioablation (STAR), a non-invasive treatment option for refractory ventricular tachycardia (VT), faces challenges from combined respiratory and cardiac motion, necessitating large target margins or motion mitigation. Respiratory gati...
