To explore window settings technology in the digital radiography of pneumoconiosis, and to improve the quality of the digital chest radiographs. 25 female workers in a asbestos product processing enterprise were examined with high-kV and DR chest radiographies on same day. Consistency of pneumoconiosis diagnosis were assessed. Results In the 75 groups of radiograph quality results, there are 62 groups that need to be processed window in order to make the correct diagnosis. The crude agreement among two chest radiographs was 28% for the profusion of small opacities and 76% for the classification of pneumoconiosis, the weighted kappa value (κ) was 0.33 (95%: 0.12-0.54) and 0.67 (95%: 0.42-0.92) . window settings technology can display different parts of chest and make DR chest radiograph to meeting the requirements of chest radiograph quality for pneumoconiosis.
探讨尘肺病数字X线摄影中的窗技术设置，以提高数字化胸部X线片的质量。对某石棉制品加工企业的25名女职工同一天进行高千伏及DR胸部X线摄影检查，评估尘肺病诊断的一致性。结果在75组胸片质量结果中，有62组需要进行窗处理才能做出正确诊断。两张胸片对小阴影密集度的粗一致性为28%，对尘肺病诊断分级的粗一致性为76%，加权kappa值（κ）分别为0.33（95%：0.12 - 0.54）和0.67（95%：0.42 - 0.92）。窗技术设置能显示胸部不同部位，使DR胸片达到尘肺病胸部X线片质量要求。
