摘要
质子治疗具有肿瘤区域剂量适形度高,周围危及器官所受辐射少的特点,对于减少患者的放疗辐射损伤具有重要的意义。准确地计算出患者体内的剂量分布是质子精准治疗的必要条件,因此,质子治疗计划系统是质子治疗中不可或缺的关键部分。本文对质子治疗计划系统及其所使用的剂量算法的研究进展进行综述。
Proton therapy can deliver highly conformal dose distribution to the targeted organs or tissues while minimizing radiation exposure to surrounding normal tissues.These characteristics of proton therapy have great significance for reducing patients'radiation injuries.Proton therapy has to be performed based on accurate calculation of the dose distributions inside the patients'body and the proton treatment planning system is thus an indispensable part of proton therapy.The paper intends to provide a review on recent progress in dose algorithm research for proton therapy planning system.
