目的探讨CR尘肺高千伏摄影图像的质量管理与控制。方法对2000张高千伏胸片按质量标准评价分析。重点分析三级片及废片产生的原因。结果CR高千伏胸片中一级片占76.6%,二级片占21.9%,三级片占1.2%,废片占0.3%。三级片及废片缺陷依序为画面、位置、伪影、锐利度、对比度。结论采用CR尘肺高千伏摄影,需要注意多个方面的质量管理与控制。
Objective To investigate the quality management and control of high-kV photographic images of pneumoconiosis in the CR. Methods 2000 high kilowatts chest radiograph according to the quality standard evaluation analysis. Focus on the analysis of three films and the causes of scrap pieces. Results High-kV chest radiographs accounted for 76.6% of primary films, secondary films accounted for 21.9%, tertiary films accounted for 1.2%, waste accounted for 0.3%. Three films and waste film defects in order for the screen, location, artifacts, sharpness, contrast. Conclusion The use of CR pneumoconiosis high kV photography, need to pay attention to many aspects of quality management and control.
