论文摘要
在质子治疗中，决定范围的范围和远端斜率，这反映了质子减速的速率，如果我们要确保确保准确的剂量沉积和最大的组织保留，则将是重要的。该出版物描述了GEANT4模型，并在能量，能量扩散和带有高斯能量光谱的光束的远端斜率之间呈现了二维多项式关系。这种简单的多项式关系将可用于非侵入性或微创的近乎实时监测质子治疗束的能量和能量扩散。
In proton therapy both the energy, which determines the range, and the distal slope, which reflects the rate at which the protons decelerate, are of import if we are to ensure accurate dose deposition and maximum tissue sparing. This publication describes a Geant4 model and presents a two-dimensional polynomial relationship between energy, the energy spread and the distal slope for beams with Gaussian energy spectra for proton therapy. This simple polynomial relationship will be useful for non-invasive or minimally invasive near real-time monitoring of the energy and energy spread of a proton therapy beam.
