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.
