自大跃进以来,天津开始试制 X 线膠片,现在已能大量生产,供应各地。预计今年该厂生产 x 结膠片的数量更大,将充分地满足国内的需要。当我们伟大的祖国自己能制造 X 线膠片的消息传出后,特别是见到国产的 X 线膠片时,我们放射学的工作人员是多么兴奋!自从国产片开始供应以来,我院即开始使用,现已以使用国产膠片为主,并应用于特殊检查摄影。兹将我们积累的初步经验介绍如下:在开始使用国产片时,本科摄得的片子,其质量的确有所降低,但这必须从我们本身的技术上来找原因。根据我们工作的实际经验,发现国产片要求比原有的摄影条件高,也就是说要用较高的电压、进行摄影。如果用原来的摄影条件所摄得的片子则无法诊断,但如果用更高的电压摄影,则表现为黑白对比不佳,片子发灰。有时,所用的摄影时间也需要适当的延长。如何找出国产片所需要的合适的摄影条件,是我们研究的主要课题之一。我们是这样进行的:从所摄各 Since the Great Leap Forward, Tianjin began trial production of X-ray film, which has now been mass-produced and supplied all over the country. It is estimated that the factory will produce a larger amount of x-ray film this year and will fully meet the domestic needs. Our radiology staff is so excited when we see X-ray films made in China by our great motherland, especially when it comes to X-ray films made domestically. , Is now mainly used for domestic film, and applied to special inspection photography. We will introduce our initial experience as follows: At the beginning of the use of domestically produced films, undergraduate film quality has indeed declined, but this must be from our own technical reasons. According to the actual experience of our work, we found that domestic film requirements than the original photography conditions, that is to use a higher voltage for photography. If you use the original photography conditions of the film can not be diagnosed, but if you use a higher voltage photography, the poor performance of black and white, the film gray. Sometimes, the use of photographic time also need to be extended. How to find out the appropriate photography conditions for domestic films is one of the main topics we study. We do this: From what we take
