摘要

Cobb角是评价脊柱畸形的主要诊断参数。传统上，它是在二维冠状射线(x射线)图像上测量的。在这项研究中，我们提出了一种半自动算法，用于从脊柱的三维网格模型评估Cobb角。对22个脊柱模型进行了测试，与参考测量值的平均绝对误差为2.89°，表明该方法具有良好的性能。

Semi-automated measurement of the cobb angle from 3D mesh models of the scoliotic spine

The Cobb angle is the main diagnostic parameter for evaluating spinal deformities. Traditionally, it is measured on two-dimensional coronal radiographic (X-ray) images. In this study, we present a semi-automated algorithm for the evaluation of the Cobb angle from three-dimensional mesh models of the spine. The method was tested on 22 spine models, and the obtained mean absolute error of 2.89° against reference measurements indicates that the method performs well.
