Objective To research the normative operation method of digital mammography for optimizing image quality,so as to improve the diagnostic accuracy of pathological changes.Methods Four thousand cases of mammography images were analyzed retrospectively.Each radiography operation method was evaluated in image quality classification.The relationship between mammography operation and image quality was analyzed.Results There were 15,012 images classified as class I,which accounted for 97.35% among all 15,420 images,and 376 images(2.44%) were class II,which were caused by patient's bad cooperation,abnormal operation of technician and other causes of equipment problem.Thirty two images(0.21%) needed re-operation of mammography due to severely low image quality.Conclusion For acquisition of high quality of mammography images,normative mammography operation and periodical equipment image quality calibration are essential.
