中文摘要：
稳固变换的煤气的察觉者的一种新类型为高精力 X 光检查被调查工业计算断层摄影术(HECT ) 。变换效率被在 Linux 平台上使用埃格斯恩尔克·蒙蒂·卡洛代码在察觉者模仿光子和电子的运输进程计算。如果 X 光检查横梁宽度是不到大约 0.2 公里，变换效率能是超过 65% 的模拟结果表演，和有 0.2 公里厚度和 30 公里长度的一个钨平板作为放射变换媒介被采用。同时，结果显示这个新察觉者有更高的变换效率以及更少的体积。理论上，察觉者的这种新类型能为 HECT 传统的焕发察觉者发生。
英文摘要：
A new type of solid-conversion gas detector is investigated for high energy X-ray industrial computed tomography （HECT）. The conversion efficiency is calculated by using the EGSnrc Monte Carlo code on the Linux platform to simulate the transport process of photons and electrons in the detector. The simulation results show that the conversion efficiency could be more than 65%, if the X-ray beam width is less than about 0.2 mm, and a tungsten slab with 0.2 mm thickness and 30 mm length is employed as a radiation conversion medium. Meanwhile the results indicate that this new detector has higher conversion efficiency as well as less volume. Theoretically this new kind of detector could take place of the traditional scintillation detector for HECT.
