JO - Frontiers in oncology VL - 14 SN - 2234-943X CY - Lausanne PB - Frontiers Media M1 - DKFZ-2024-02399 SP - 1417393 PY - 2024 N1 - #EA:E041# AB - The focus of this article is to describe the configuration, testing, and commissioning of a novel gantry-less synchrotron-based proton therapy (PT) facility.The described PT system delivers protons with a water equivalent range between 4 and 38 cm in 1800 energy layers. The fixed beam delivery permits a maximum field size of 28 × 30 cm2. The patient positioning and imaging system includes a six-degree-of-freedom robotic arm, a convertible patient chair, a vertical 4DCT, and an orthogonal 2D X-ray imaging system.The spot positioning reproducibility was consistent within ±1 mm. The width (σ) of the beam profile at the isocenter was energy dependent and ranged from 2.8 mm to 7.7 mm. Absolute dose reproducibility was measured and deviations were found to be <0.62 KW - calibration (Other) KW - commissioning (Other) KW - dosimetry (Other) KW - gantry-less patient positioning (Other) KW - intensity modulated proton therapy (Other) KW - pencil beam scanning (Other) KW - quality assurance (Other) KW - synchrotron (Other) LB - PUB:(DE-HGF)16 C6 - pmid:39575421 C2 - pmc:PMC11578985 DO - DOI:10.3389/fonc.2024.1417393 UR - https://inrepo02.dkfz.de/record/294664 ER -
