摘　　要：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。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,, c, arefully designed. . repho,tography, is class a Conclusion： the high qt]alitfimages needs not only advanced magingtechnology equipment and operation, at the same time requires accurate position placement and elaborate design, All three are short of one cannot.
