摘 要:目的:分析干式激光胶片的结构、成像原理与图像发生质变的原因。方法:抽取干式激光、湿式激光胶片和普通X线胶片各60张,档案室保存的3种胶片各100份,观察3种胶片在相同包装与温、湿度环境中的变化。结果:A组胶片在自然环境中放置300min,有10张无包装、4张塑料袋包装和1张纸袋包装的干式激光胶片图像发生变化;B组胶片在人工温度环境中放置120min,3组干式激光胶片图像都发生变化,对照组的2种胶片在相同环境中试验420min无异常变化;档案室保存的3种胶片均无异常变化。结论:干式激光胶片影像易受存放环境温、湿度条件和包装袋材质种类的影响发生质变,影响图像质量。Objective To research the structure, imaging mechanism and quality of dry view laser imaging film. Mothods We extracted 60 pieces of dry view laser imaging film, wet view laser imaging film and ordinary film respectively. Each tape of films was divided into 3 groups in 100 pieces each. They were observed in the same temperature and humidity. Results Group A was observed after 300 minutes, the dry view laser films image of 10 pieces without package, 4 pieces packed with plastic and 1 piece packed with paper changed. After 120 minutes, group B was observed; the dry view laser imaging film in different packing had the different changes. To the contrast, the wet laser imaging film's images didn't change in the same humidity and temperature after 420 minutes test. Conclusion The imaging of dry laser imaging film with different temperature, humidity and package will easily affect the image quality. [Chinese Medical Equipment Journal, 2009,30(9) : 101-103,105]
