项目摘要

This research project proposed new concept of computer-aided diagnosis (CAD) called NavI-CAD and tried to implement prototypes of the NavI-CAD. The NavI-CAD enables us to navigate the inside of a virtualized human body constructed from higher-dimensional medical images. This research project made the meaning of navigation used in the NavI-CAD clear with implementing several prototypes of the NavI-CAD. We have presented that navigation in the NavI-CAD is performed along several axes of the physical and the logical spaces. In the implementation of the NavI-CAD, we made prototypes including NavI-CAD for Chest, NavI-CAD for Colon, and NavI-CAD for whole body. Also, we have developed several image processing and visualization techniques that are required in these NavI-CAD systems. Furthermore, we have developed the multi-organ and multi-disease computer-aided diagnosis system called Pluto as the basic platform that enable us to easily develop a NavI-CAD system. In the development of the Nav … More I-CAD for Chest, we have investigated (1) lung lobe division algorithm, (2) automated nomenclature algorithm of bronchial branches, (3) segmental lobe division algorithm based on results of automated nomenclature of bronchial branches, (4) intelligent navigation-based diagnosis algorithm based on segmentation of organs in the chest area, (5) intelligent path generation algorithm for bronchoscopy using segmentation results, and (6) assistance system for real bronchoscopy using NavI-CAD. In the development of the NavI-CAD for Colon, we have developed methods for (1) genetation of virtual stretched views of the colon and (2) automated polyp detection based on analysis of Hessian matrix of intensities. In the development of the NavI-CAD for Whole Body, we have succeeded in development of (1) automated lymph node detection and (2) new visualization method that enables us to observer vessels along with them. In development of the multi-organ and multi-disease computer-aided diagnosis system (Pluto), we have developed the software platform and distributed that system to all members of this priority area. Also, we have integrated the research results of this priority area through the plug-ins of the Pluto. Less

本研究项目提出了计算机辅助诊断(CAD)的新概念--NAVI-CAD，并尝试实现了NAVI-CAD的原型。Navi-CAD使我们能够在由更高维度的医学图像构建的虚拟人体内部进行导航。本研究项目通过实现导航CAD的几个原型，明确了导航CAD中导航的含义。我们已经提出，在Navi-CAD中，导航是沿着物理和逻辑空间的几个轴执行的。在Navi-CAD的实现中，我们制作了包括胸部的Navi-CAD、结肠的Navi-CAD和全身的Navi-CAD的原型。此外，我们还开发了这些Navi-CAD系统所需的几种图像处理和可视化技术。此外，我们还开发了多器官、多疾病计算机辅助诊断系统Pluto，作为基础平台，使我们能够轻松地开发Navi-CAD系统。在开发导航…的过程中针对胸部的I-CAD，我们研究了(1)肺叶分割算法，(2)支气管镜自动命名算法，(3)基于自动支气管镜命名结果的分段肺叶分割算法，(4)基于胸部器官分割的智能导航诊断算法，(5)基于分割结果的支气管镜检查智能路径生成算法，以及(6)基于Navi-CAD的真实支气管镜检查辅助系统。在开发Navi-CAD for Colon的过程中，我们开发了(1)生成虚拟的结肠拉伸视图和(2)基于Hessian强度矩阵分析的自动息肉检测方法。在全身NAVI-CAD的开发中，我们成功地开发了(1)自动淋巴结检测和(2)新的可视化方法，使我们能够同时观察血管。在开发多器官和多疾病计算机辅助诊断系统(冥王星)的过程中，我们开发了软件平台，并将该系统分发给这一优先领域的所有成员。此外，我们还通过冥王星的插件集成了这一重点领域的研究成果。较少
