摘要:
目的 对上海市数字化乳腺x射线摄影装置使用情况与设备性能质量状况进行对比分析，为合理选择数字化乳腺x射线摄影装置提供参考。方法 依据国家相关标准和规范，采用x射线检测仪和乳腺成像性能检测模体，对上海市53台数字化乳腺x射线摄影装置的9项技术指标进行质量控制检测，并将两类数字化乳腺x射线机——计算机x射线摄影装置（cr）与数字x射线摄影装置（dr）的性能检测结果进行统计学分析。在分析两类乳腺机各项性能指标合格率差异的基础上，对两类乳腺机的乳腺平均剂量与图像质量进行进一步的比较分析。结果 两类乳腺x射线机的合格率及乳腺平均剂量差异无统计学意义；对于模体影像，两类设备的差异具有统计学意义，dr乳腺机的图像质量优于cr乳腺机。结论 应加强对数字化乳腺x射线摄影装置的日常检测，从辐射防护最优化角度推荐选择dr乳腺机代替cr乳腺机开展数字化乳腺摄影工作。
Abstract:
objective to investigate the application and quality status of digital mammography facilities in shanghai. methods in accordance with national standard and regulations, 9 technical parameters of 53 digital mammography facilities in shanghai were tested using x-ray test tools and image quality test phantom. the performances of digital radiography（dr） and computed radiography（cr） systems were compared on the basis of the tested parameters by using spss17.0 software. the qualified rates of all tested parameters were compared. further comparisons were performed in the two types of digital mammography facilities in terms of average glandular dose and image quality. result no statistically significant difference was found in the qualified rate and averaged glandular dose between dr and cr mammography systems. the image quality of the dr system is better than that of the cr system with statistically significant difference. conclusion radiation protection for dr mammography systems should be optimized. status test is very important to maintain the quality of digital mammography facilities.
