点X射线发射是从由一个石墨-石墨冷阴极和一个圆锥形的铜金属阳极组成的二极管配置。当与具有闪烁体的高灵敏度电荷耦合器件（CCD）相机组合时，该X射线源然后用于获得钨网和X射线测试图的X射线透射图像。该X射线照相系统的空间分辨率为10 μ m的顺序和这些图像的采集时间小于10秒。点X射线源和灵敏检测系统的这种组合提供了高分辨率X射线照相系统。(C)2003年，美国物理学会。
A point x-ray emission was obtained from a diode configuration composed of a graphite-nanofiber cold cathode and a conical-shaped copper metal anode. When combined with a highly sensitive charge coupled device (CCD) camera with a scintillator, this x-ray source was then used to obtain x-ray transmission images of a tungsten mesh and an x-ray test chart. The spatial resolution of this x-ray radiography system was on the order of 10 mum and the acquisition time for these images was less than 10 s. This combination of the point x-ray source and the sensitive detection system offers a high-resolution x-ray radiography system. (C) 2003 American Institute of Physics.
