【摘要】 目的 :为了帮助临床医生学习颅底解剖,创建一个颅底三维模型。方法 :应用冷冻铣切技术,获得横断和冠状薄层断面照片,对于系列照片进行分割、标志、提取颅底结构信号,然后通过Amira 3D软件,重建了1个颅底三维模型。结果 :共获得了780张冠状断面和430张横断面图片,在这些断面上,颅底的一些精细解剖结构可以被追踪。成功重建的颅底3D模型可以在任何模式旋转和缩放。但是,因为该模型是在2个头部标本的基础上建立的,颅底解剖的变异不能被该模型显示。结论 :重建的3D模型可以准确展示颅底解剖结构,它有利于外科解剖培训,可用来完成术前的手术模拟。更多还原

【Abstract】 Objective : To create a three-dimensional(3 D) model of the central skull base for doctors to master the regional anatomy. Methods : Continuous thin sections in the transverse and coronal planes were performed with the freezing milling technique. After segmenting, labeling, and extracting organs in serial sections, we reconstructed the 3 D model of the central skull base using Amira software. Results : Seven hundred and eighty thin coronal sections, four hundred and thirteen transverse sections of the base region in central skulls were obtained. The salient structures could be tracked across sections. A 3 D model of the central skull base that can be rotated and zoomed in an arbitrary fashion was successfully produced. There were some non-anatomical anomalies in the model because it was reconstructed with organs from two head spicimens. Conclusion : The 3 D model of the central skull base displays fine anatomical features. It is beneficial for surgical education in general and provides a means of preoperative rehearsal of skull-base surgical procedures.更多还原
