Abstract

A method for modelling and visualizing human lungs using knowledge of lung anatomy and high resolution CT (HRCT) images is presented. The model consists of a symbolic description of lung anatomy and a 3D atlas. The 3D atlas is constructed using HRCT volume data. A few anatomical landmarks are determined and are used to divide the lungs into anatomically and diagnostically important regions. The landmarks and the lung regions enable accurate mapping of the model to patient data and enable the system to deal with image and human variability. The model can be displayed as a set of labelled axial slices and as a 3D model of the lungs. The 3D visualization enables rotation and viewing of lung structures, lung features and lung regions from different angles.
人体肺的三维建模和可视化
提出了一种利用肺解剖学知识和高分辨率CT (HRCT)图像对人体肺进行建模和可视化的方法。该模型由肺解剖的符号描述和三维图谱组成。利用HRCT体数据构建三维地图集。确定了一些解剖标志,并用于将肺划分为解剖学和诊断上重要的区域。地标和肺区域使模型能够准确地映射到患者数据,并使系统能够处理图像和人类的可变性。该模型可以显示为一组标记轴向切片和肺的3D模型。3D可视化可以从不同角度旋转和观察肺结构、肺特征和肺区域。
