摘　　要：神经外科手术中,手术入路造成的缺损颅骨修复是重要研究内容之一。该研究提出了一种结合光学手术导航系统在术中快速重建缺损颅骨三维结构的方法。该方法利用术中缺损边缘点和术前医学影像数据,实现在术中自动三维重建缺损颅骨结构的算法。通过头模实验来评估方法效果,结果显示右眼眶缺损重建的平均误差是0.424 mm,后颅底缺损重建的平均误差是0.377 mm。实验结果表明分割出来的缺损结构与实际缺损吻合,重建精度满足临床要求。In neurosurgery,skull repair caused by surgical approach is one of the important research contents.In this paper,a rapid reconstruction method of the skull defect with optical navigation system is proposed.This method can automatically reconstruct the structure of skull defect with the intraoperative defect edge points and preoperative medical image data.The head model experiment was used to evaluate the effect of the method,the average error of the reconstruction of the defect in the right orbit was 0.424 mm,while the average error of the reconstruction of the defect in the posterior skull base was 0.377 mm.The experimental results show that the structure of the defect is consistent with the actual defect,and the reconstruction accuracy satisfies the clinical requirements in neurosurgery.
