中国数字化人体鼻部结构的三维重建和可视化

目的建立可视化人体的鼻部相关结构的三维模型。方法采用中国首例女性数字化可视人体数据集（CVH-2）,选取从额窦顶到上颌窦底消失水平连续横断面图像,在计算机上利用Amira4.1软件和RadioDexter软件行三维重建的立体显示。结果重建出了鼻骨,额窦,筛窦,蝶窦,上颌窦,鼻腔,上、中、下鼻甲,鸡冠,鼻中隔,钩突,鼻泪管,颈内动脉,视神经的三维可视化模型。该模型可以任意缩放和任意角度旋转,可显示不同结构间的毗邻关系和空间构象,并可进行三维的距离和角度的测量。结论鼻部相关结构的三维可视化模型可促进对该部位解剖结构的理解和掌握,为鼻部疾病影像诊断和鼻内镜手术提供了形态学参考,并可应用于虚拟手术。

3D reconstruction and visualization of nasal anatomical structures of the Chinese digitized human

Objective To build a digitized visible model of nasal anatomical structures.Methods Data of the cross-sectional image range of the first set of Chinese visible human female database（CVH-2） from the top layer of the frontal sinus to the bottom layer of the maxillary sinus were used in this study.The contour of organs was segmented from the cross-sectional images and 3D reconstructed by the Amira 4.1 and Radio-Dexter software in a computer.Result We successfully reconstructed 3D visible models of the main nostril structures,such as the nasal bone,frontal sinus,ethmoidal sinus,sphenoidal sinus,maxillary sinus,nasal cavity,superior,middle or inferior nasal turbinate,crista galli,nasal septum,uncinate process,nasolacrimal canal,internal carotid artery,and optic nerve.These models could be displayed from any directions,and the spatial positions and adjacent relationships of different anatomical structures,also the reconstructed structures could be determined in 3D space.Conclusion These visible nasal models have facilitated observing and understanding of the anatomical structures in this area,provide the morphological data for imaging diagnosis of nasal diseases and nasal endoscopic surgeries,and also could be used in virtual surgeries.
