下背痛（LBP）等腰椎病变的诊断非常困难，关于诊断标准尚未达成共识。准确测量椎间运动学参数有助于了解相关疾病的病因和诊断，并对后续治疗进行评价。介绍了定量荧光透视（QF），它可以在低辐射剂量下获得腰椎运动的连续、动态图像序列。椎间运动学的估计依赖于腰椎的精确定位。通常，通过自动方法或手动方法来识别和跟踪椎骨角。本研究提出了一种基于KLT（Kanade-Lucas-Tomasi，KLT）椎间运动学分析算法的椎体跟踪新方法。使用包含两个椎体的矢状面人体图像测试所提出的方法的准确性，并且所实现的位移和角度的平均误差分别在0.25 mm和0.3°之内。为了在临床条件下测试所提出的方法，共招募了11名志愿者，并与经验丰富和训练有素的临床医生的手动方法相比，获得了椎间运动学更平滑和稳定的结果。总之，所提出的方法是一种有效的，准确的方法来评估腰椎跟踪。
The diagnosis of lumbar spine pathologies such as lower back pain (LBP) is extremely difficult, and a consensus regarding a diagnostic standard has not yet been reached. Accurate measurement of intervertebral kinematic parameters helps to understand the etiology and diagnosis of related diseases, and to evaluate the subsequent treatment. Quantitative fluoroscopy (QF) which can obtain continuous, dynamic image sequences of lumbar motion at low radiation doses were introduced. The estimation of intervertebral kinematics depends on the precise localization of lumbar vertebrae. Usually, vertebral corners are identified and tracked by automated methods or manual method. This study presents a novel method for vertebral tracking based on the KLT (Kanade-Lucas-Tomasi, KLT) algorithm for intervertebral kinematics analysis. Accuracy of the proposed method was tested using a sagittal human image which contained two vertebral bodies, and the average errors achieved for displacement and angle were within 0.25 mm and 0.3°, respectively. To test the proposed method under clinical conditions, totally 11 volunteers were recruited and a result of more smoothness and stability in the intervertebral kinematics was obtained with comparing to the manual method by an experienced and trained clinician. In conclusion, the proposed method is an effective, accurate way to assess lumbar vertebrae tracking.
