讨论了一个模型，该模型描述了传统管中X射线的产生，使用表列的韧致辐射能谱，取决于三个变量：靶原子序数，入射电子动能和辐射能量的分数。所构建的模型包括技术管参数，如千伏、靶材料和靶角度，以考虑靶中的自吸收，以及射线照相参数，如滤波。此外，模型中还包括特征辐射的无参数描述。借助仿真工具，可以单独研究参数的影响。测量结果表明了该模型的有效性。本研究由德国联邦经济和技术部根据合同MNPQ转让II D 5 - 30/06支持。
A model is discussed which describes the generation of X‐rays in conventional tubes using tabulated Bremsstrahlung energy spectra depending on three variables: the target atomic number, the incident electron kinetic energy, and the fraction of energy radiated. The constructed model includes technical tube parameters like kilovoltage, target material and target angle to also account for self‐absorption in the target, as well as radiographic parameters like filtering. Additionally a parameter‐free description of the characteristic radiation is included in the model. With the help of the simulation tool the influence of parameters can be separately studied. The validity of the proposed model is shown by measurements. This research is supported by the German Federal Ministry of Economics and Technology under contract MNPQ transfer II D 5‐30/06.
