To evaluate transient output variation immediately following gantry rotation in a compact synchrocyclotron‑based proton therapy system, with focus on quantifying magnitude of output deviation between initial post‑rotation measurement and subsequent stabilized...
To develop a single-setup machine QA framework for multiple tests across different gantry angles in proton therapy. Current monthly QA procedures require separate setups to verify proton beam characteristics, including output consistency, scanning magnet perf...
To evaluate the necessity of verification imaging at couch-angle positions for brain and head-and-neck (HN) patients treated with immobilization masks by analyzing setup accuracy and reproducibility using a year-long retrospective dataset.
To clinically implement C-RAD for gated beam delivery on a Mevion S250i Hyper scanning machine for thorax and abdomen patients.
To introduce and evaluate a rotational phantom that enables full‑angle patient‑specific QA (PSQA) in proton therapy using a standard, commercially available ion‑chamber‑based detector. The focus of this work is to develop an angle‑dependent PSQA workflow suit...
To identify key factors influencing proton beam delivery accuracy with a Mevion Hyperscanning system equipped with Adaptive Aperture, and to address parameters contributing to patient-specific quality assurance (PSQA) failures through planning technique optim...
