It is notoriously difficult to quantify the kinematic behaviour of vertebral segments in the assessment and localization of mechanical disorders of the spine. This paper describes the use of an image processor and an X-ray machine with image intensifier for the measurement of lumbar spine angular rotation and instantaneous centres of rotation in the coronal plane. The system was calibrated against a model under realistic conditions employing multiplanar motion and X-ray scatter.
在评估和定位脊柱机械性疾病时，量化椎体节段的运动行为是出了名的困难。本文描述了使用图像处理器和带有影像增强器的X光机来测量腰椎在冠状面内的角旋转和瞬时旋转中心。该系统在实际条件下，针对采用多平面运动和X光散射的模型进行了校准。
