目的:探讨腹部直接数字化X射线摄影(DR)中,采用均衡处理技术的DR图像与标准DR图像的差别。方法:自我院2003年4月以来的DR腹部影像中,顺序抽取200例作为分析材料,运用均衡处理技术对图像进行处理,比较均衡DR图像与标准DR图像的差别。结果:均衡DR图像可在同一幅上清晰显示不同组织的细节,标准DR图像需调节窗宽﹑窗位才可清晰显示。结论:运用均衡处理技术能明显改善不同组织的可视性,且不损失其他部分的细节显示,使DR的应用更完善,操作更便捷,病变的检出率更高。
Objective: To explore the difference between DR image and standard DR image using equalization in direct digital radiography (DR) in the abdomen. Methods: From the abdomen imaging of our hospital since April 2003, 200 cases were taken as the analysis materials and the images were processed by the equalization technique. The differences between the balanced DR images and the standard DR images were compared. Results: The balanced DR images can clearly show the details of different tissues on the same frame. The standard DR images need to be adjusted for window width and window level to be clearly displayed. Conclusion: The use of equalization techniques can significantly improve the visibility of different tissues without losing the details of the other parts of the show, so that the application of DR more perfect, easier to operate, the detection rate of lesions higher.
