摘要

目的　探讨利用2D/3D配准技术开展直立位颈椎椎间孔形态学测量的可行性研究。方法　采集7位健康成年志愿者颈椎的CT影像，对其进行三维重建获得颈椎三维模型，并采集同一志愿者保持同一姿势时的颈椎直立正侧位X线平片，在图像处理软件Mimics中建立虚拟X线场景，采用2D/3D图像配准还原摄平片时颈椎的位置，并利用Rapidform XOR3软件测量两种位置的椎间孔面积。结果　利用2D/3D图像配准方法，可获得颈椎直立位的三维位置数据，共测得56个椎间孔卧位及直立位两位置椎间孔面积,卧位椎间孔面积为(50.9±14.2) mm2，直立位椎间孔面积为(83.6±23.5) mm2，差异具有统计学意义（t=-8.107，P<0.05）。结论利用2D/3D配准技术可获得颈椎直立位椎间孔的形态学参数，直立位与卧位椎间孔有显著差异，但其准确性需要进一步的研究验证。

Abstract

Objective To investigate the feasibility of orthostatic cervical transforaminal morphologic measurements using 2D/3D registration techniques. Method Seven healthy adult volunteer's cervical spines were CT scanned and then 3D reconstructed; And two orthogonal X-ray images of cervical vertebrae in the same orthostatic posture were also harvested. A virtual fluoroscopic scene was then created in software Mimics and wasused to reproduce the relative positions of the orthogonal images using 2D/3D image registration technology. Transforaminal morphologic measurements were performed in Software Rapidform. Result The cervical orthostatic posture could be reproduced and the morphologic data, such as inter foraminal area, could be calculated. A total of 56 intervertebral foramen were measured in supine and upright positions: supine foramen area was ??(50.9±14.2) mm2 and orthostatic foramen area was ??(83.6± 23.5) mm2, showing significant difference(t= -8.107, P<0.05 ). Conclusion Orthostatic cervical transforaminal morphological parameters could be calculated using2D/3D registration techniques. However, it’s efficiency and accuracy need further investigation.
