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.
