摘要

本文提出了一种基于模型的IMRT治疗方案,在不影响周围健康组织特别是桨叶的情况下,将最大剂量的规定剂量传递到靶点,以产生最佳辐射剂量。Fluence映射用于逆规划。该方法可以在不同的治疗计划中产生具有可靠计划质量的IMRT计划的全局最小值,并有效地为重要的平行桨提供更好的安全性。整个方法具有处理各种目标的能力,并生成有效的处理程序,并通过CORT数据集上的插图进行验证。为了验证我们的方法,我们将我们的结果与其他两种基于剂量-体积界限计算目标的方法进行了比较,发现在我们的方法中,通过前列腺和淋巴结的剂量是最大的,收敛所需的时间是最小的。

Fluence map optimisation for prostate cancer intensity modulated radiotherapy planning using iterative solution method
Abstract Here we projected a model-based IMRT treatment plan to produce the optimal radiation dosage by considering that the maximum amount of prescribed dose should be delivered to the target without affecting the surrounding healthy tissues especially the OARs. Fluence mapping is used for inverse planning. This suggested method can generate global minima for IMRT plans with reliable plan quality among diverse treatment planners and to provide better safety for significant parallel OARs in an effective way. The whole methodology is having the capability to handles various objectives and to generate effective treatment procedures as validated with illustrations on the CORT dataset. For the validation of our methodology, we have compared our result with the two other approaches for calculating the objectives based on dose-volume bounds and found that in our methodology dose across the prostate and lymph nodes is maximum and the time required for the convergence is minimum.
