上海医疗器械厂生产的XG200型X线机,在遮光器上设有X线管角度指示器(以下简称指示器),指示X线管沿台面纵轴的倾斜角度,这是此型X线机的独特之处。如果把指示器加以改进,就可以扩大它的应用范围,不仅能指示X线管沿台面纵轴的倾斜角度,还可以指示X线管倾斜角度后新的立柱高度和中心线移动距离,与该机之移动台面配合使用,既提高摄影质量,又提高效率。现把改进和应用方法介绍如下,供参考。改进方法指示器的式样与原指示器相同,为提高其准确度,可把指示器作得大一些,指针要
The XG200 X-ray machine produced by Shanghai Medical Device Factory is equipped with an X-ray tube angle indicator (hereinafter referred to as indicator) on the shutter to indicate the tilt angle of the X-ray tube along the longitudinal axis of the table. Unique. If the indicator is improved, it can be expanded its scope of application, not only can indicate the tilt angle of the X-ray tube along the longitudinal axis of the table, but also indicate the height of the new column and the center line movement distance after the X-ray tube tilt angle, Machine with the use of mobile table, both to improve the quality of photography, but also improve efficiency. Now to improve and apply the method described below, for reference. Improve the style of indicator The same as the original indicator, in order to improve its accuracy, the indicator can be made larger, the pointer to
