In order to provide a uniform and desirable dose distribution over a large radiation field, spot beam scanning is one of the most useful methods. A new spot beam scanning system was constructed for a 70 MeV proton beam. The lateral dose distribution was uniform with +/- 2.5% for an 18 cm square field. It was possible to control the dose at each point in the radiation field by this spot scanning method. This system has been confirmed to be satisfactory for delivering a proton beam in the desired field shape and dose level.
为了在大辐射野上提供均匀且理想的剂量分布，点束扫描是最有用的方法之一。为70 MeV质子束构建了一种新的点束扫描系统。对于18 cm×18 cm的射野，横向剂量分布均匀度为±2.5%。通过这种点扫描方法可以控制辐射野中每个点的剂量。该系统已被证实能以所需的射野形状和剂量水平满意地输送质子束。
