摘要：

背景：由于颈胸段侧位摄影时，成像区域的组织厚薄相差大，且重叠多，即使数字X射线摄影具有曝光动态范围大，图像能进行多种后处理的功能，但数字X射线摄影的常规摄影也难以显示颈胸段的解剖结构来了解病情，颈胸段正侧位数字X射线摄影影像质量需要进一步提高。
目的：比较应用直接数字X射线摄影组织均衡技术产生的颈胸段图像和直接数字X射线摄影产生的标准数字X射线摄影图像的差别，在颈胸段摄影中探究最佳图像质量。
方法：从解放军总医院放射科2005-04/2009-08所摄的数字X射线摄影颈胸段影像中按随机数字表法抽取200例作为分析资料，应用直接数字X射线摄影组织均衡技术对标准数字X射线摄影图像进行处理，比较组织均衡图像与标准数字X射线摄影图像的差别。
结果与结论：应用直接数字X射线摄影组织均衡技术产生的新的图像，在同一幅图像上下颈上胸段的细节均可清晰显示；标准数字X射线摄影图像需要反复调节不同的窗宽、窗位才能清晰显示下颈上胸段的细节。提示在直接数字X射线摄影中，应用组织均衡技术能明显改善被检体受厚度影响而不容易观察的细节，同时，又不影响其他部位的细节显示。操作简便，可提高诊断率，减少误诊率，减少成本。

Abstract:

BACKGROUND: Differences of thick and thin tissues in imaging areas is great because of postero-anterior images in cervical spine-thoracic spine. Although there are many image processing functions in direct digital radiography (DR) image with big range dynamic exposing, but routine direct DR hardly reveals anatomic structure of cervical spine-thoracic spine to detect diseases. Image quality of cervical spine-thoracic spine requires improvement.
OBJECTIVE: To evaluate the difference between direct DR image with tissue equalization (TE) technique and standard DR in cervical spine-thoracic spine, so as to explore the best image quality in cervical spine-thoracic spine.
METHODS: A total of 200 cases were randomly selected from DR cervical thoracic image from Department of Radiology, General Hospital of Chinese PLA between April 2005 and August 2009 to evaluate the difference between these images of DR processed by tissue equalization and that of standard DR.
RESULTS AND CONCLUSION: The detail images of DR with tissue equalization in different thickness area of body could be revealed clearly in the same image, while the detail images of standard DR in cervical thoracic could be revealed clearly by adjusting window width and location repeatedly. Results show that the image quality of TE technique of direct digital X-ray radiography in cervical spine-thoracic spine could be clearly improved, it could be easily read and avoid the influence of body thickness area. Moreover, it could reveal clearly other part of body in detail. DR image with TE technique in cervical spine-thoracic spine can be applied widely due to simple operation, high diagnosis rate and low cost.
