通用粒子和重离子输运代码PHITS进行了修改，以改进碳治疗系统中剂量分布的分析。我们在PHITS中增加了两个新功能，一个用于能量色散计算，另一个用于交流磁场中的输运，这首次实现了碳治疗系统的三维建模。用该程序计算了碳治疗系统的剂量分布，计算结果与实验数据吻合较好。这种改进的PHITS是设计碳治疗孔径或估计治疗计划中的剂量分布的有价值的工具。
The general purpose particle and heavy ion transport code, PHITS, was modified for improved analysis of dose distribution in carbon therapy systems. We added two new functions into PHITS, one for an energy dispersion calculation and the other for transport in an AC magnetic field, which enabled 3-dimensional modelling of a carbon therapy system for the first time. With this code we calculated the dose distribution in a carbon therapy system, and these results showed good agreement with experimental data. This improved version of PHITS is a valuable tool for the design of carbon therapy aperture or for the estimation of the dose distribution in treatment planning.
