在日常工作中,常需制作CT图像的幻灯片,而美国GE公司生产的SYTEC 2000型CT机没有设置35mm胶卷摄影装置,给幻灯片的制作带来困难。笔者利用该机的视频反转功能（VIDEO REVERSE）解决了这一问题。l 材料和方法 一架手动的35mm单镜头反光照相机,配置50mm或70mm镜头;三角架一付;快门线一根;胶卷采用中国乐凯胶片公司生产的型号为5143的乐凯牌黑白电影正片;显影液用普通D-72或D-76显影粉配制;定影液用普通X线照片定影液即可。
In daily work, it is often necessary to make slides of CT images. However, the SYTEC 2000 CT machine manufactured by GE Company of the United States does not have a 35mm film camera, which makes it difficult to make slides. I use the machine’s video inversion function (VIDEO REVERSE) to solve this problem. l Materials and methods A manual 35mm single-lens reflex camera with 50mm or 70mm lens, one tripod and one shutter release film. The film is a positive black-and-white film made by China Lucky Film Co., The developer is prepared with ordinary D-72 or D-76 developer; the fixing solution is to be set with a normal X-ray fixing solution.
