【摘要】 与一般的重离子相比,~9C离子束在治疗肿瘤方面具有明显的优势。为了获得~9C离子在含肿瘤Snyder修正头部模型内的能量沉积、核碎片分布以及核碎片注量随靶体深度的分布,本文采用蒙特卡罗程序FULKA模拟计算了290MeV/u~9C离子束在含肿瘤Snyder修正头部模型靶体中的输运过程。论文的研究为~9C离子束治疗恶性肿瘤的剂量学提供了理论参考。更多还原

【Abstract】 Compared with other heavy ions,carbon-9 ions beam has a obvious advantage in the treatment of cancer.Simulation calculation for 290MeV/u Carbon-9 ions beam transport in tumor modified Snyder head phantom is done with Monte Carlo programmer FLUKA in this paper.Energy deposited,does,nuclear fragments distribution and fluence change of nuclear fragments with depth of the target produced by 290MeV/u ~9C ions beam interaction with tumor modified Snyder head phantom are obtained by simulation calculation.Thesis provides a theoretical for the dosimetry of future malignant tumors treatment with ~9C ion beam.更多还原
