A Comprehensive Comparative Study of Proton Flash Techniques for Conformal Pencil Beam Scanning Radiotherapy: Pristine Bragg Peak Vs. Spread-out Bragg Peak

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...

Commissioning the First Upright Proton Therapy System with Matched Beam Quality In a Synchrotron Based Two-Room Facility

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...

Dosimetric Feasibility of Flash-Compatible Single-Energy Bragg Peak (SEBP) Proton Therapy for Hypofractionated Pancreatic Cancer

Hypofractionated proton therapy for pancreatic cancer is limited by the proximity of radiosensitive abdominal organs. Single-energy Bragg peak (SEBP) proton delivery enables ultra-high dose-rate (UHDR) irradiation and may facilitate FLASH compatible treatment...
