求最佳笔形射束强度分布是调强放疗治疗计划制定中的关键部分,传统的方法以模拟退火算法为基础,文中采用了一种模拟退火的改进算法,实验表明,该方法在求解的效率和质量方面都较前者有明显改善。
The best pencil beam intensity distribution is the key part in the planning of IMRT. The traditional method is based on the simulated annealing algorithm. In this paper, an improved simulated annealing algorithm is used. The experimental results show that the efficiency of this method in solving the problem And the quality of the former have significantly improved.
