摘　　要：目的　探讨胸部直接数字化X线摄影 (DR)中 ,采用组织均衡技术的DR图像与标准DR图像的差别。方法　从我院2 0 0 3 -0 5所摄的DR胸部影像中按顺序抽取 10 0例作为分析材料 ,通过运用组织均衡技术对图像进行处理 ,比较组织均衡图像与标准DR图像的差别。结果　运用组织均衡技术的图像 ,同一幅图像上不同体厚部位的细节均可清晰显示 ;标准DR图像需调节不同的窗宽、窗位才能清晰显示不同体厚部位的细节。结论　在直接数字化X线摄影中 ,运用组织均衡技术能明显改善先前受体厚影响而难于观察部分的可视性 。Objective To investigate the advantages of DR images produced by tissue equalization(TE)technique in chest digital radiography(DR) compared with standard technique.Methods 100 images collected from DR chest images taken in our hospital in May,2003 were processed by TE technique and compare with standard DR images.Results The details in different thickness area of body could be revealed clearly in the same image produced by TE technique,while the display parameters should be adjusted repeatedly to reveal the details in standard chest digital radiography.Conclusion The visualization of image details can be obviously improved by using the TE technique and other details are not lossed.
