摘　　要：目的寻求建立颈椎后路手术相关结构数字模型及三维可视化方法。方法取健康志愿者头顶至第3胸椎下缘连续CT/MRI断面图像,Mimics软件对骨骼,肌肉,神经等组织用半自动方法进行分割和重建,MedCAD(医学计算机辅助设计)模块对细小解剖结构重建,三维化显示颈椎后路手术相关解剖结构。结果建立颈椎后路手术相关结构的三维可视化模型,显示骨性结构、颈背部由浅入深4层17组肌肉、4组韧带、C1～T2脊神经后支和颈部浅层肌等解剖结构的位置关系。结论在颈背部三维可视化模型基础上,参照解剖学层次逐层显示该手术相关重要结构,为该手术解剖教学、手术培训提供医疗教学平台。Objective To explore the method for establishing digital model and three-dimensional visualization of the correlated structures of posterior cervical approach.Methods Basing on CT and MRI continuous 2-Dimensional pictures from the vertex to the inferior border of the T3 of one healthy volunteer,half-auto cut and reconstruction was taken on skeleton,muscles and nerves with the Mimics software.The tiny anatomic structures were reconstructed with the MedCAD module.Three-dimensional model of posterior cervical approach and its surrounding structures was successfully displayed.Results A three-dimensional digital model of the correlated structures of posterior cervical approach was established.The position relation of different structures was successfully presented,such as the skeleton;17 groups of muscles covering the nape,formed 4 layers from the superficial to the deep;4 kinds of ligaments;ramus posterior nervorum spinalium of C1-T2;and the superficial cervical muscles.Conclusions On the basis of three-dimensional visualization model of the nape,the correlated important structures of posterior cervical approach can be displayed step by step,which is a favorable tool for anatomic teaching and operation training.
