【摘要】：目的探讨车载直接数字化X射线摄影(DR)与车载高千伏(HKV)2种胸部摄影方法的优缺点,阐明DR技术在粉尘作业人员职业健康检查中的应用价值。方法随机选取煤尘作业人员87名,分别进行胸部车载DR和车载HKV摄影。将胸片按摄影方法分为DR组和HKV组,对2组胸片摄影质量及其分级、尘肺病X射线胸片表现等进行比较分析。结果 HKV组胸片符合胸片基本要求、解剖标志显示良好和曝光度适中的符合率分别为62.07%、88.51%和72.41%,DR组的符合率分别78.16%、98.85%和100.00%。HKV组胸片优、良和差废片率分别为40.23%、36.78%、22.99%,无检出观察对象;而DR组胸片优、良和差废片率分别为78.16%、20.69%、1.15%,检出2例粉尘作业人员观察对象。结论车载DR技术条件易于控制,其胸片质量优于HKV胸片,相对更适用于粉尘作业人员的职业健康检查。
[Abstract]:Objective to explore the advantages and disadvantages of (DR) and (HKV) in direct digital X-ray photography, and to elucidate the application value of DR technique in occupational health examination of dust workers. Methods 87 coal dust workers were randomly selected for DR and HKV photography. The chest radiographs were divided into DR group and HKV group according to the method of radiography. The quality and grade of chest radiography and the X-ray chest radiographic manifestations of pneumoconiosis were compared and analyzed between the two groups. Results the chest radiographs in HKV group were in accordance with the basic requirements of chest radiography. The coincidence rates of good anatomical signs and moderate exposure were 62.0788. 51% and 72.41% respectively, and the coincidence rates of Dr group were 78.16% and 72.41%, respectively. The chest radiographs of 98.85% and 100.00%.HKV groups were excellent, and the rates of good and poor spent films were 40.23 and 36.78, respectively. There were no observed objects. In DR group, the rates of excellent, good and poor spent films were 78.16 and 20.699.15, respectively, and 2 dust workers were detected. Conclusion the technical condition of on-board DR is easy to control and the quality of chest X-ray is better than that of HKV, which is more suitable for occupational health examination of dust workers.
