目的介绍一种检测医用Ｘ线胶片观察灯亮度的新方法。方法在对工业亮度测量方法深入研究的基础上，根据几种人体组织的典型Ｘ线胶片密度，设计了对应的图形标志并用Ｘ线技术拍报成卡。结果很方便地实现了医用Ｘ线胶片观察灯亮度的日常检测。结论为Ｘ线胶片观察灯的日常检测提供了一种简单而有效的工具，为执行世界卫生组织（ＷＨＯ）要求的ＱＡ、ＱＣ工作的深入开展提供了保证。
Objective To introduce a new method of detecting the brightness of medical X-ray film observation lamps. Methods Based on the in-depth study of industrial brightness measurement methods, according to the typical X-ray film density of several kinds of human tissues, corresponding graphic marks were designed and X-ray filming was performed. The result is very convenient to achieve the daily detection of medical X-ray film observation lamp brightness. Conclusion The simple and effective tool for the routine inspection of X-ray film observation lamps provides a guarantee for the implementation of QA and QC required by the World Health Organization (WHO).
