description: This work is devoted to the implementation of a method for controlling the combination of the X-ray radiation isocenter of the kV imaging system and the radiation isocenter of the active proton beam scanning system. The aim of the study is to conduct a comprehensive assessment of the accuracy of the coincidence of the central axes of radiation sources and the localization of the isocenter of the Varian ProBeam proton therapy system. A cone-shaped XRV-124 scintillation detector was used to measure the proton radiation isocenter. To check the effect of the Gentry angle on the coincidence of rays, measurements were carried out in the study at 8 different Gentry angles with a step of 45, in addition, 3 different energy values were used to determine the regularity of its influence on the coincidence of rays. The coincidences of the rays along the X, Y and Z axes were within Â± 1.5 mm for 3 different energies at 8 Gentry angles. The results of the combination of rays ranged from 0 to 1.52 mm in the transverse direction (X), from -1.23 to 0.40 mm in the vertical (Y) and from -1.15 to 1.14 mm in the longitudinal (Z), and the size of the isocenter was 0.5 mm. The described method makes it possible to achieve submillimeter accuracy in determining the coincidence of X-ray and radiation isocenters and is suitable for daily quality control of the clinical department of proton radiation therapy.
