乳腺数字钼靶X射线摄影体位对图像质量的影响探讨

摘要

Objective: Explore photography position of mammary gland molybdenum target X-ray digital image quality. Methods: To choose from June 2011-June 2012 1120 patients for 4320 patients of mammary gland molybdenum target X-ray digital image analysis, image classification statistics of different position of photography, the unqualified reason caused by the image and the influence factors are analyzed. Results: Not class a piece of 292 images in the 4320 images, not percent of pass is 6.76%, unqualified 81 of non-artificial factors, unqualified reason is due to changes in patients mammary gland, unable to obtain high quality images, accounted for 27.74%, improper operation and set 211, accounted for 72.26%, above that are caused by unqualified image after carefully designed rephotography is class a Conclusion:the high quality images needs not only advanced imaging technology equipment and operation, at the same time requires accurate position placement and elaborate design, All three are short of one cannot.%目的：探讨摄影体位对乳腺数字钼靶X射线图像质量的影响。方法：选择1120例患者的4320幅数字钼靶X射线图像进行比较，对不同摄影体位的图像进行分级统计，对不合格图像造成的原因及影响因素进行分析。结果：4320幅图像中非甲级片292幅，不合格率为6.76%，其中非人为因素造成不合格图像81幅(占27.74%)，不合格原因是由于患者乳腺变化，无法获得高质量的图像；操作及摆位不当211幅(占72.26%)。以上人为因素造成的不合格图像经过精心设计重摄后，均得到了甲级片。结论：高质量的图像不仅需要先进的影像设备与操作技术，同时需要精确的体位摆放及精心设计，且三者缺一不可。
