| 摘 要： | 在硼中子俘获治疗(BNCT)的蒙特卡洛(MC)剂量计算中,通常使用单一的网格模式,如16mm,8mm,4mm.使用细网格计算资源太大,使用粗网格,计算精度不够,为此,根据粒子穿透深度和计数量的变化梯度,采用混合网格模拟计算,达到了细网格的精度,时间仅为细网格的37%.

| Abstract: | Single mesh size phantoms are usually used in the calculations of BNCT dose rate by Monte Carlo method, such as 4mm, 8mm, 16mm. The result with 16mm mesh size model simulations produce unacceptable accuracies. Although the 4mm model simulation has a good precision, it costs lots of memories and computation time. The mixed mesh size model has the same precision as 4mm model, but its computation time is only 37% of that. |
