旨在验证锥形束计算机断层扫描（CBCT）颈椎建模与三维（3D）-3D配准在颈椎运动学体内测量中的准确性。CBCT模型的准确性通过与10名健康年轻人的计算机断层扫描（CT）模型叠加进行验证，然后在5名健康年轻人中，在功能运动的6个末端位置与中立位置对颈椎进行配准。计算并报告配准误差和六个自由度（6-DOF）运动学。相对于CT模型，CBCT模型的平均偏差< 0.6 mm。末端位置和参考中间位置之间的平均配准误差< 0.7 mm。在屈伸（F-E）过程中，三个方向的平移都很小，大多数< 1 mm，LB和AR耦合均< 1°。在侧向弯曲（LB）期间，弯曲大致均匀分布，C1-C2处的耦合轴向旋转（AR）与LB相反，并且耦合F-E最小。AR时，C1-C2节段旋转最多（左旋29.93 ± 7.19°，右旋31.38 ± 8.49°），并出现与AR相反方向的耦合LB。模型匹配证明了颈椎运动学数据的亚毫米精度。目前评价的低辐射剂量CBCT技术可用于测量功能F-E、AR和LB位置的体内3D脊柱运动学，这对于上颈椎尤其具有挑战性。
To validate the accuracy of Cone beam computed tomography (CBCT) cervical spine modeling with three dimensional (3D)-3D registration for in vivo measurements of cervical spine kinematics. CBCT model accuracy was validated by superimposition with computed tomography (CT) models in 10 healthy young adults, and then cervical vertebrae were registered in six end positions of functional movements, versus a neutral position, in 5 healthy young adults. Registration errors and six degrees of freedom (6-DOF) kinematics were calculated and reported. Relative to CT models, mean deviations of the CBCT models were < 0.6 mm. Mean registration errors between end positions and the reference neutral position were < 0.7 mm. During flexion–extension (F–E), the translation in the three directions was small, mostly < 1 mm, with coupled LB and AR both < 1°. During lateral bending (LB), the bending was distributed roughly evenly, with coupled axial rotation (AR) opposite to the LB at C1–C2, and minimal coupled F–E. During AR, most of the rotation occurred in the C1–C2 segment (29.93 ± 7.19° in left twist and 31.38 ± 8.49° in right twist) and coupled LB was observed in the direction opposite to that of the AR. Model matching demonstrated submillimeter accuracy in cervical spine kinematics data. The presently evaluated low-radiation-dose CBCT technique can be used to measure 3D spine kinematics in vivo across functional F–E, AR, and LB positions, which has been especially challenging for the upper cervical spine.
