摘　　要：利用纹理映射和刚体变换配准方法,实现了女护理人模型图像结合中国数字女虚拟人数据集重建的解剖模型得到医学增强现实模型的显示。图像引导脑囊肿手术仿真中增强显示了脑囊肿、手术探针、颅骨、脑组织、护理人皮肤和MRI医学图像,显示了术前手术路径及周围脑解剖结构,增强了外科医生手术的真实感和精确性。Texture warping and rigid registration were used to combine the image of female nurse model and the anatomical model of the Virtual Chinese Human-Female dataset to achieve the medical augmented reality model. During image guided surgery simulation of brain cyst, the cyst tissue, probe, skull, brain lobes, nurse model skin and MRI medical images were interactively shown on medical augmented reality model. At the same time, the preoperative surgical procedures and the adjacent anatomical structure improved the realistic and accurate operation for surgeon.
