OBJECTIVE
To assess Mimics as a new measurement method in Cobb angle in a comparison with traditional measurement and try to explore the advantages and disadvantages of the new method.
METHODS
Twenty X-ray plates of scoliosis were chosen randomly. Two experienced physicians measured the Cobb angles via Mimics and traditional methods twice with an interval of 1 week. And statistical analyses of Cobb angle and difference between two measurements were carried out.
RESULTS
The overall correlation was 0.986 for Mimics and traditional measurements. ANOVA demonstrated no significant difference between these two methods. A significant difference existed between the first and second values of Cobb angle in Mimics and traditional measurements. However the absolute difference was small.
CONCLUSION
Mimics can be a new method for measuring the digital radiographs. And its precision is superior to that of the traditional measurement.
目的
与传统测量方法相比，评估Mimics作为测量Cobb角的一种新方法，并探讨该新方法的优缺点。
方法
随机选取20张脊柱侧弯的X线片。两名经验丰富的医生通过Mimics和传统方法对Cobb角进行两次测量，间隔1周。并对Cobb角及两次测量之间的差异进行统计分析。
结果
Mimics测量与传统测量的总体相关性为0.986。方差分析表明这两种方法之间无显著差异。Mimics测量和传统测量中Cobb角的第一次和第二次测量值之间存在显著差异。然而，绝对差异很小。
结论
Mimics可作为一种测量数字X线片的新方法。其精度优于传统测量方法。
