This paper deals with the theoretical basis for radiographic magnification. In particular, the relationship between focal size and optimal magnification for various systems is discussed. Maximal resolution was chosen as the criterion for best results. It has been shown that resolution (Lp-mm) can be improved by the reciprocal of the focal spot and for optimal magnification (see article) where f is focal spot size and AVBW is resolution of the imaging system.
本文探讨了X射线放大成像的理论基础。特别讨论了各种系统中焦点尺寸与最佳放大倍数之间的关系。选择最大分辨率作为最佳结果的标准。结果表明，分辨率（线对/毫米）可通过焦点尺寸的倒数来提高，对于最佳放大倍数（见文章），其中f为焦点尺寸，AVBW为成像系统的分辨率。
