A previously existing X-ray stereophotogrammetric method which allows the measurement of simultaneous changes in all components of a scoliotic deformity was developed without the use of invasive methods or skeletal markers. In order to evaluate the changes in rotation and lateral deviation of the scoliotic curve following treatment with the Boston brace, this method was applied to 31 patients suffering from idiopathic scoliosis. The derotational effect of the brace averaged 14 degrees (0-38 degrees) in 21 patients remaining after rejection of those whose radiographs were of inadequate quality. The accuracy, however, was not acceptable because of frequent gross errors due to the poor quality of the radiographs. Image interpretation may be improved by a suggested technique of enhancement based upon a computer program for figure restauration and border detection.
一种先前存在的X射线立体摄影测量方法被开发出来，该方法无需使用侵入性方法或骨骼标记物，就能测量脊柱侧凸畸形所有组成部分的同时变化。为了评估使用波士顿支具治疗后脊柱侧凸曲线的旋转和侧方偏移变化，该方法应用于31例特发性脊柱侧凸患者。在排除X线片质量不佳的患者后，21例患者中支具的去旋转效果平均为14度（0 - 38度）。然而，由于X线片质量差导致频繁出现严重误差，其准确性无法接受。基于用于图像恢复和边界检测的计算机程序的一种建议增强技术，可能会改善图像解释。
