摘要
提出了称之为复合歧离算法的中能重离子束深度剂量分布计算方法 ,并计算了中能C ,O离子束的Bragg相对剂量分布曲线 ,同实验测量结果进行了比较 ,计算与实验测量符合得很好 .证实了复合歧离算法的合理性及由它计算Bragg曲线的可靠性 .
A complex straggling algorithm is presented to calculate depth dose distribution of intermediate energy heavy ion beam. Relative dose Bragg curves of carbon and oxygen ion beams with intermediate energies were computed according to the algorithm above. Comparisons between the relative doses predicted and measured were taken up. The Bragg curves predicted by the complex straggling algorithm show a good agreement with the experimental data. So the reasonableness of this algorithm and its reliability for calculating depth doses were verified. Hence the principle and method to deduce the depth dose distribution of therapeutic beam was integrated after this algorithm was developed.
