摘要：Graphical abstractDisplay OmittedAbstractA compact beam-position monitor was constructed using a linear contact image sensor attached to a plastic scintillator and tested using a 230 MeV proton beam. The results indicate that the beam position can be obtained in real-time, and the beam position with a precision of up to 0.03 mm. The compactness and high precision of the device hold considerable potential for it to be used as a beam-position monitor and offline, daily quality assurance monitor in hadron therapy.•The method can provide a high precision and high resolution beam position for flash irradiation in particle therapy in real-time.•The method using contact image sensor with scintillator does not require a long focal length for camera and it is free of image distortion.•The method can be integrated into medical particle accelerator for feedback control and daily quality assurance.
