观片灯标识方法及装置
摘要：
本发明涉及一种观片灯标识方法及装置，主要用于射线照片观片灯的合理利用。所述方法包括以下工艺过程：将观片灯表面用一黑纸遮住，在黑纸中央开一个Φ4mm孔；将一具有不同黑度值孔的标准密度片的孔分别对准Φ4mm孔，检测各孔所能透过的亮度，若某一孔所能透过黑度D1满足JB/T4730.2-2005所规定的黑度D的要求，则将该黑度值记录下来，制作标签贴在观片灯上。该观片灯可以适合观察底片黑度为2.0～D1的胶片。本发明从根本上解决了观片灯的标识、合理利用问题。
摘要（英）：

The invention relates to a method and device for marking a view box, which are used for the reasonable utilization of a radiograph film viewer. The method comprises the following technical processes: the surface of the film viewer can be shielded by black paper, and a hole with a 4mm diameter is arranged in the center of the black paper; and holes of a standard density film with different density values are respectively aligned to the hole with the 4mm diameter, the brightness capable of penetrating through each hole can be detected, the density value can be recorded if the requirement of the density D regulated by JB/T4730.2-2005 is satisfied by the density D1 capable of penetrating through one hole, and the blackness value can be used for making a label to be adhered on the film viewer. The film viewer can be suitable for viewing a film with the film density of 2.0-D1. According to the method and the device disclosed by the invention, the problem of marking and reasonably utilizing the film viewer is fundamentally solved.
