摘　　要：目的使用CT图像的三维重建技术将腰椎椎弓崩裂的图像以三维立体的方式显示出来,为外科手术提供最好的图像支持。方法用3D打印技术做出与真实的腰椎密度相似的且带有骨折裂痕的腰椎模型,使用CT对椎体模型进行最小层厚扫描,并将扫描的图像进行三维重建。结果①CT扫描的分层图像对受伤部位显示清晰;②三维重建后的图像对骨折的显示效果不理想。结论CT扫描的分层图像是显示椎弓崩裂的最优方法,三维立体的图像只能起到辅助作用。Objective:To use 3D rebuilding technology of CT image showing lumbar vertebral arch fracture,and provide the best imaging support for surgery.Methods:The model of lumbar vertebral arch fracture was first built by 3D printing,then the image was obtain by CT scanning model,and 3D rebuilding technology was used to proceed image.Results:①Single layer image of CT showing lumbar vertebral arch fracture was clear.②The 3D image couldt show lumbar vertebral arch fracture clearly.Conclusion:Single layer image of CT is fit for showing lumbar vertebral arch fracture,and the 3D image plays an assistant role..
