摘要:

我们提出了一个多尺度的方法来了解物理相关的离子束癌症治疗。它允许计算DNA损伤的概率,作为组织的高能离子照射的结果,高达430 MeV/u。这种方法涵盖了不同的尺度,从大尺度开始,由离子停止定义,然后是较小的尺度,由次级电子和自由基定义,并以最短的尺度结束,由次级电子与DNA的相互作用定义。我们提出了计算的DNA单链和双链断裂的概率,提出了一种方法,以进一步扩大这种计算,并暴露于辐射的神经胶质细胞也作出了一些估计。

英文摘要:

We propose a multi-scale approach to understand the physics related to ion-beam cancer therapy. It allows the calculation of the probability of DNA damage as a result of irradiation of tissues with energetic ions, up to 430 MeV/u. This approach covers different scales, starting from the large scale, defined by the ion stopping, followed by a smaller scale, defined by secondary electrons and radicals, and ending with the shortest scale, defined by interactions of secondaries with the DNA. We present calculations of the probabilities of single and double strand breaks of DNA, suggest a way to further expand such calculations, and also make some estimates for glial cells exposed to radiation.
