ABSTRACT

A ‘transXend’ detector measures X-rays as electric current and yields an X-ray energy spectrum after analysis. Response functions are necessary for the analysis and are previously estimated using material details of the X-ray detector. The detector specifics, however, are not always available to users. Here, a ‘response-function-less’ transXend detector is described that relies on transmission measurements of X-rays that passed through known basis materials. The validity of the method is verified by obtaining effective atomic numbers for nine resins.

带有无响应函数 transXend 检测器的能量分辨计算机断层扫描

摘要

“transXend”探测器将 X 射线作为电流进行测量，并在分析后产生 X 射线能谱。响应函数是分析所必需的，并且是使用 X 射线探测器的材料细节预先估计的。然而，检测器的细节并不总是对用户可用。在这里，描述了一种“无响应函数”的 transXend 探测器，它依赖于通过已知基础材料的 X 射线的透射测量。通过获得九种树脂的有效原子序数验证了该方法的有效性。
