| 摘 要： | 根据感光效应原理和影像增强电视系统的性能，在一定的焦－片距下，透视mA与kV相匹配，图像质量满意；而在相同的焦－片距下，点片用稀土增感屏，则点片mAs与kV相区配也能得到图像质量良好的X光片。那么用相同的kV而找到mA对应的mAs,则点片条件的设定有了参照，此方法明显优越于经验点片，且在特殊部位点片更显优越。

| Abstract: | According to the photosensitive effect theory and the features of radiography enhancing TV system, the quality of image is satisfied if matching mA with KV in a certain focus-film distance, or if matching mAS with KV as using the rare-earth sensitive screen. So if the relation between mAS and mA is found for the same KV, then there is a reference to establish the photographic conditions. This method obviously is better than experienced method to get good quality film. |
