荧光摄影的基本原理是以照相机将荧光屏上的影像摄取下来,因此这是一种间接摄影的方法。又因它所摄得的影像是较荧光屏的影像按比例缩小的,所以又称为荧光缩影或间接缩影。这种装置主要用于防痨或其它职业病的集体X线检查。其特点是效率高,成本低,节省胶片,适于作集体健康检查。可将此装置安装于汽车上,便于到工厂、农村作集体检查之用,十分方便。 通常的荧光摄影装置主要为摄取的胸部影像的,虽然原理简单,但要使摄得之小片具有极高的诊断价值并且与大片同等价值,因此要充分估计到若干的技
The basic principle of fluorescence photography is that the camera takes down the image on the screen, so this is an indirect method of photography. And because the image it captures is scaled down from the screen’s image, it is also called a fluorescent or indirect miniature. This device is mainly used for collective X-ray examination of phlegm or other occupational diseases. Its characteristics are high efficiency, low cost, saving film, suitable for collective health inspection. This device can be installed on a car, which is convenient for the collective inspection in factories and rural areas. The conventional fluoroscopic apparatus is mainly for ingestion of chest images. Although the principle is simple, it is necessary to make the captured small pieces have extremely high diagnostic value and have the same value as large pieces, so it is necessary to fully estimate the number of techniques.
