摘要：
A new beam course dedicated to proton radiation therapy was constructed at NIRS (National Institute of Radiological Sciences, Japan). The vertical beamline, which is assumed to be suitable for radiation therapy, has a scatter, wobbler magnets, monitor ionization chambers, a range shifter, a range modulator, a multileaf collimator and other patient-positioning devices. A simulation program for beam propagation in a beam port was developed in order to estimate beam profiles for any proton radiotherapy beam course. The results of the beam profile obtained by the simulation program were compared with the experimental results and were found to be in good agreement.
