在栅扫描束流配送系统下,进行了重离子束对运动靶体进行适形照射的可行性实验研究．利用实时修正束流扫描参数的方法,使得束流追踪靶体在横向上的运动；在纵向上利用一个机械驱动的束流降能装置(称深度扫描器)迅速调节束流能量,使得重离子束高剂量的Bragg峰区落在运动靶体需治疗的断层之上．实验结果表明：栅扫描器主动补偿靶体横向运动及深度扫描器补偿靶体纵向运动是可行的． Under the grid scanning beam distribution system, the feasibility experiment of heavy ion beam for conformal illumination of moving target was carried out. The method of real-time correction of beam scanning parameters is adopted to make the beam track the movement of the target in the horizontal direction. In the longitudinal direction, a mechanically driven beam current reduction device (called a depth scanner) is used to rapidly adjust the beam energy such that the heavy ions The high dose Bragg peak area falls above the fault to be treated by the moving target. The experimental results show that it is feasible for the gate scanner to compensate the lateral movement of the target and the depth scanner to compensate the longitudinal movement of the target.
