AbstractIn proton radiotherapy, a round dose profile at the isocenter is beneficial to the treatment planning in the active scanning mode. Based on the theory of the round-beam method, a collimator was designed to be placed at the entrance of the gantry. A simulation of Monte Carlo method was done to validate the design scheme. With the constraining function of the collimator, the dose profile at the isocenter would maintain a round shape despite of an initial asymmetric phase space in extraction of synchrotron. Furthermore, the shape of dose profile is irrelevant to the rotating angle of the gantry. The mechanical error caused by the axis deviation of the gantry could also be partly eliminated with the collimator. (C) 2015 Elsevier B.V. All rights reserved.
