摘　　要：目的探讨数字化乳腺摄影的摆位操作技巧,以提高图像质量。方法取本院两个连续的时间段,分别以旧的摆位方法摄取的X线数字乳腺图像1600例(假定为A组)和改进的摆位方法摄取的X线数字乳腺图像1600例(假定为B组),共3200例。由1位副主任医师和2位主管技师对上述3200例图像资料进行质量分析统计,统计出两组图像各自的甲级片和非甲级片率,并对非甲级片产生的原因进行分析。结果A组非甲级片22%,其中约3%是由于患者病情导致乳腺外表变化,不能配合检查,图像不能达到正常诊疗所需;另外19%皆由于技师的操作不当或不细心所引起,大部分重拍可以改正。B组非甲级片8%,其中约3%是由于患者病情导致乳腺外表变化,不能配合检查,图像不能达到正常诊疗所需。结论选取适当的投影方法及良好的摆位技巧能提高照片图像质量,更好地显示病灶,从而辅助诊断。Objective To study the Digital Mammography Positioning Technique in order to improve the image quality. Methods Two groups of Digital Mammography image were taken by two ways in defcrent period of time. One group （ group A） were taken by traditional way while the other group （ group B） by new Positioning Technique. Two groups of image were evaluated by terms of quality and compared. Results 19% of group A are unqualified while group B only has 5% unqualified. Conclusion Appropriate photography method and good Positioning Technique may improve image quality.
