摘　　要：目的分析高千伏X线胸片质量的影响因素,提高胸部高千伏摄影水平。方法 500例粉尘作业人员尘肺病普查的胸部高千伏X线片为调查组,其中300例摄有同期数字放射线照相术(DR)胸片作为对照组。由5名具有尘肺病诊断资格的专业人员组成评价小组,对每份胸片进行客观评价,比较2组胸片的质量差异,分析评价结果,列举影响高千伏胸部X线片环节质量的常见因素。结果调查组优片率、良片率、差片率和废片率分别为38.00%、59.00%、2.40%对和0.60%,与对照组比较,差异有统计学意义(P<0.01)。技术环节及人为因素是造成高千伏X线胸片质量下降的主要原因。结论胸部高千伏X线摄影的影响因素较多,只有加强环节质量控制,才能有效地提高胸片质量。[Objective]To analyze the influencing factors of high kilovoltage（KV） chest radiographs quality,and raise the photography level. [Methods]Chest high KV radiographs of 500 dust exposed workers in pneumoconiosis census were identified as an investigation group,among which,300 workers who had the chest digital radiographs（DR） synchronization were selected as a control group.The evaluation team formed by 5 professionals who had the pneumoconiosis diagnosis qualifications evaluated each chest radiograph objectively,quality differences of 2 group were compared,evaluation results were analyzed,and the common factors influencing the high KV chest radiograph quality were enumerated. [Results]The superior film rate,the good film rate,the bad film rate and the wasted film rate of investigation group was 38.00%,59.00%,2.40% and 0.60% respectively,compared with control group,the differences were significant（P0.01）.The technical aspects and the human factors were the primary causes of decline in the quality high KV radiograph. [Conclusion]The chest high KV radiograph are influenced by many factors,only the strengthening quality control can effectively improve the chest radiograph quality.
