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% for all possible beam scenarios. The built-in dose monitoring system was successfully tested for its ability to generate interlocks under specific conditions (beam spot deviation ≥2 mm, individual spot dose ≥10% or ≥0.25 Gy, spot energy deviation ≥0.5 MeV). The robot positioning exhibited a consistent reproducibility within ±1 mm. All tested scenarios achieved laser-free initial 3D/3D image-guided positioning within ±5 mm. Subsequent 2D/3D positioning showed an accuracy of ±1 mm. A single 2D/3D image registration event corrected positions in all cases. Results of gamma analysis (3%, 3 mm) demonstrated pass rates greater than 95% for head and neck, thorax, abdomen treatment plans.We report on the performance of a novel single-room gantry-less PT system comprised of a compact synchrotron and an adjustable (from nearly horizontal to almost vertical) patient positioning system. The commissioning results show high accuracy and reproducibility of the main proton beam parameters and the patient positioning system. The new PT facility started patient treatments in March 2023, which were the first in Israel and the Middle Eastern region. 000294664 536__ $$0G:(DE-HGF)POF4-315$$a315 - Bildgebung und Radioonkologie (POF4-315)$$cPOF4-315$$fPOF IV$$x0 000294664 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000294664 650_7 $$2Other$$acalibration 000294664 650_7 $$2Other$$acommissioning 000294664 650_7 $$2Other$$adosimetry 000294664 650_7 $$2Other$$agantry-less patient positioning 000294664 650_7 $$2Other$$aintensity modulated proton therapy 000294664 650_7 $$2Other$$apencil beam scanning 000294664 650_7 $$2Other$$aquality assurance 000294664 650_7 $$2Other$$asynchrotron 000294664 7001_ $$0P:(DE-He78)0704701d58e3a0d5f45fbd1018d5aa77$$aPryanichnikov, Alexander$$b1$$eFirst author$$udkfz 000294664 7001_ $$aAchkienasi, Alejandro$$b2 000294664 7001_ $$aPolyansky, Ilya$$b3 000294664 7001_ $$aHillman, Yair$$b4 000294664 7001_ $$aRaskin, Stas$$b5 000294664 7001_ $$aBlumenfeld, Philip$$b6 000294664 7001_ $$aPopovtzer, Aron$$b7 000294664 7001_ $$aMarash, Michael$$b8 000294664 773__ $$0PERI:(DE-600)2649216-7$$a10.3389/fonc.2024.1417393$$gVol. 14, p. 1417393$$p1417393$$tFrontiers in oncology$$v14$$x2234-943X$$y2024 000294664 909CO $$ooai:inrepo02.dkfz.de:294664$$pVDB 000294664 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)0704701d58e3a0d5f45fbd1018d5aa77$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000294664 9131_ $$0G:(DE-HGF)POF4-315$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vBildgebung und Radioonkologie$$x0 000294664 9141_ $$y2024 000294664 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bFRONT ONCOL : 2022$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2021-05-11T13:25:45Z 000294664 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2021-05-11T13:25:45Z 000294664 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Anonymous peer review$$d2021-05-11T13:25:45Z 000294664 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ$$d2021-05-11T13:25:45Z 000294664 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2023-10-26 000294664 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2023-10-26 000294664 9201_ $$0I:(DE-He78)E041-20160331$$kE041$$lMed.
