质子治疗代表着外照射放疗最先进的技术之一。相对于普通放疗用的光子 (X 射线和 γ 射线) 和电子射线,质子束具有其独特的物理特性——布拉格峰 (Bragg peak)。基于这个特性,质子束的能量释放可以更集中地沉积在肿瘤部位,包含皮肤在内的肿瘤前方的正常组织将受到较小剂量的照射,而肿瘤之后的正常组织受到的剂量几乎为...

Polymerization is limited to the vicinity of the controlled Bragg-peak of the ion beam (i.e., where linear energy transfer is maximized), if necessary, by the use of chemical polymerization inhibitors or conditions that inhibit polymerization. This technology is more flexible than conventional or ...

Bragg peak When a fast charged particle moves through matter, it ionizes atoms of the material it encounters depositing a dose along its path and losing energy. A Bragg curve describes (plots) this energy loss of ionizing radiation as it travels through matter. The Bragg peak is a pronounced...
摘要: DefinitionDefinitionA region of large energy transfer from a proton or heavy ion. It is seen as a region of high-dose deposition at the end of the particle's range in tissue. The peak in dose occurs wDOI: 10.1007/978-3-540-85516-3_657 年份: 2013 ...

Proton irradiation exhibits an entrance portion of the beam (ENT) where dose is deposited sparsely and a Bragg Peak (BP) with virtually no 'exit dose' thereafter. ATMi renders cells uniquely hypersensitive to proton BP, and BP+ATMi may increase the response of Mismatch Repair proficient (pMMR)...
