【摘要】 目的通过探索虚拟现实技术来寻找一种施行经前后路联合治疗腰椎转移性肿瘤的途径。方法基于腰椎64排螺旋CT连续薄层二维图像,Mimics软件分别重建正常腰椎、破坏病椎、腹主动脉及双侧肾脏的三维可视化结构,在三维模型拟行经过前路病灶清除、钛网骨水泥支撑和后路椎弓根螺钉内固定术。结果基于Dicom格式数据进行三维重建图像结构清晰,可真实再现病椎和邻近脏器的结构,整个虚拟仿真手术真实直观。结论虚拟仿真手术可准确重建腰椎恶性肿瘤及邻近结构的三维立体结构,明确病椎清除范围,经后路重建脊柱序列,能为患者个体化治疗方案提供客观依据。更多还原

【Abstract】 Objective Through the exploration of virtual simulation surgery to find a way to treat lumbar spinal metastases. Methods Based on 64 row spiral CT continuous 2-dimensional images of lumbar segments,normal lumbar vertebral,destruction of disease,abdominal aorta and kidneys were reconstructed by the Mimics software. 3D visualization structure was contemplated by anterior lesions clear,titanium mesh of bone cement support,and posterior pedicle screw fixation. Results The three-dimensional reconstruction distinctly displayed the structures of lumbar and its adjacent organs,and the entire virtual simulation surgery was intuitive. Conclusion The application of virtual simulation surgery ensures more accurate 3D model of lumbar establishment and its adjacent organs,and it provides an objective basis for individualized treatment programs.更多还原
