摘要

摘要研究了利用双块晶体系统的衍射技术提高 X 射线图像质量的可能性。研究表明，初始辐射的低空间相干性可以提高成像质量。传统的宽焦 X 射线管可用作这种辐射源。此外，还通过数值模拟考虑了使用扫描方案来降低已形成图像中背景水平的可行性。

Improving the Quality of X-Ray Images Formed by a Diffraction Lens from a Two-Block Crystalline System

The possibility of improving the quality of X-ray images formed using diffraction on a two-block crystalline system is considered. It is shown that the low spatial coherence of the initial radiation improves imaging quality. Conventional wide-focus X-ray tubes can be used as a source for such radiation. The feasibility of using a scanning scheme to reduce the background level in the formed image was also considered by numerical simulation.
