计算机X线摄影(CR)后处理技术在颈椎常规摄影中的应用

The Computed Radiographic Post-processing Technique in Conventional Cervical Radiography

目的:评价计算机X线摄影(CR)后处理技术在颈椎常规摄影中的应用价值。方法:随机选取50例颈椎正、侧位CR片,并经密度仪测得标准测试点的密度值,观察其是否分布在胶片特性曲线的直线部分。结果:所测得的标准测试点的密度值均投影在胶片特性曲线的直线部分。结论:经过CR系统处理的颈椎正、侧位片完全符合诊断要求,并可满足不同的临床诊断需求。

Objective：To evaluate the computed radiographic post-processing technique in conventional cervical radiography.Methods： 50 cases with cervical positive and lateral CR were randomly selected,the density of the standard test point was measured by the density spectrometer,to observe whether it was distributed in the linear part of characteristic curve.Result： The density of standard test points was projected on linear part of characteristic curve.Conclusion： Cervical positive and lateral films with CR post-processing completely meet diagnostic requirement,and can meet the needs of different clinical diagnosis.
