  Pencil beam scanning (PBS) technology is a flexible and accurate dose delivery technology in proton therapy, which can deliver beams adapting to irregularly shaped tumors, while it requires precise diagnostic and real-time control of the beam dose and position. In this paper,a dose parameter acquisition and control system for the pencil beam scanning system based on the EPICS and LabVIEW is designed for HUST-PTF. The EPICS environment is built to realize the data exchange function between the front-end devices and control system. A channel access server(CAS)is designed to convert treatment parameters into the process variables (PVs) and expose them to the network for data sharing. Under current experimental conditions, the simulated beam current is generated according to the dose parameters in the treatment plan file. The current are processed by a digital electrometer and transmitted to the EPICS database in real time. Then the control system user interface based on LabVIEW is realized for displaying and parameter analysis.

  Nozzle is the core component in proton therapy machine, which is closest to the patient and is necessary to consider the radiation impacts on patients and machine. The ionization chamber and the range shifter in active scanning nozzle are the main devices in the beam path that affect the proton beam and produce secondary particles during the collision, causing damage to the patients and machine. In this paper, the spatial distribution of energy deposited in all regions, the distribution of the secondary particles of 70-250MeV proton beam in the nozzle in Huazhong University of Science and Technology Proton Therapy Facility(HUST-PTF) are studied with Monte Carlo software FLUKA in order to provide reference for radiation shielding design. Six types of materials commonly used today as range shifters are analyzed in terms of the influence on radiation, so that the most suitable material will be selected.
