The spread-out Bragg peak (SOBP) technique uses ridge filters to broaden the depth-dose profile, producing a dose distribution similar to a single-field-uniform(SFU) approach. In contrast, the single-energy pristine Bragg peak(SEPBP) approach relies on range...

We report the first clinical implementation integrating a 6D upright treatment chair and a vertical CT system for image-guided proton therapy on a synchrotron-based fixed-beamline. This design aims to improve patient workflow and reduce the facility footprint...

To implement a full abdominal motion model that combines respiration with gastrointestinal (GI) motility and quantify its interplay impact in pencil-beam scanning (PBS) proton therapy.

In radiation oncology, phase I clinical trials often test the new capabilities of a treatment machine, a novel radiopharmaceutical drug, or an untested clinical indication of radiation therapy. These trials require significant physics investment of time and e...

Accurate patient-specific dosimetry is essential for safety and efficacy in radiopharmaceutical therapy (RPT). Yet standardized approaches for commissioning dosimetry workflows are not well established. This work presents a framework for dosimetric validation...

To quantify the impact of gastrointestinal (GI) motility on pencil-beam scanning (PBS) proton therapy for abdominal cancers, and assess how fractionation and motion amplitude mitigate motility-induced interplay effects.
