Development of High Speed Virtual Bronchoscopy with Special Futures Evaluation from Medical Aspect.

(1)实现高速虚拟支气管镜和自由实时导航基于数字体积数据x线CT三维图像处理技术的最新发展，虚拟内窥镜已被临床应用。然而，它在显示器上的导航性能与真正的光学内窥镜相比没有足够的速度。我们将胸部CT的体积数据应用到基于UNIX的工作站“ONIX 2”，Silicon Graphics incorporated (SGI)，以实现更快速的虚拟导航。在onicx2上实现了高速虚拟支气管镜系统。随后，合著者之一kenaku MORI在基于Windows的PC上开发了新的虚拟内窥镜引擎，作为一种通用的分布式操作系统。快速的虚拟导航，但不是基于动画，可媲美真实的光学支气管镜是通过双CPU计算与opengl显卡。(2)虚拟支气管镜的实质功能及临床应用为了使用DICOM格式的患者三维CT数据，更符合国际医学的事实标准，我们定制了虚拟支气管镜系统。该系统还开发了一个独特的功能，可以通过支气管的高级狭窄部分和J转运动进行搜索。基于对支气管树的了解，通过计算机处理，可以自动显示支气管口的名称。可为诊断医师提供智力诊断影像支持。此外，还提供了支气管口的名称测验功能，作为教育工具。(3)结论所建立的系统将在以下情况下发挥作用。医学教育中支气管解剖学研究的教学资源医学生床侧学习支气管镜教材医学中的虚拟现实与智力诊断影像支持教材4。培训医师支气管镜的技能提升工具。5 .为了患者及其家属的利益，我们应给予知情同意。支气管镜前虚拟检查安全、顺畅，为患者提供更好的护理。基于容积绘制方法的虚拟支气管镜检查可作为下一代的诊断支持系统。少

(1)Realization of the high-speed virtual bronchoscopy and free real-time navigationVirtual endoscopy was now clinically using based on the recent development of three-dimensional image processing technology by digital volume data X-ray CT.However, its navigating performance on the display does not have enough speed compared to real optical endoscopy. We applied volume data of chest CT to UNIX dased workstation "ONIX 2", Silicon Graphics Incorporate (SGI) for more speedy virtual navigation. High-speed virtual bronchoscopy system was realized on ONIX2. Then one of the co-author Kensaku MORI developed new virtual endoscopy engine on the Windows based PC as a generally distributed operating system. Speedy virtual navigation, but was not based on the animation, comparable to real optical bronchoscopy was by dual CPU calculation with Open GL video card.(2)The substantial function of a virtual bronchoscopy and clinical applicationIn order to use patient's 3-D CT data with DICOM format which i … More s the international de facto standard in medicine, virtualized bronchoscopy system was customized. Development of a function unique to this system was also featured to make search through the advanced narrowing part of the bronchus and J turn movement. The name of a bronchus orifice could be automatically displayed by computer processing based on the knowledge of the bronchial tree. Intellectual diagnostic imaging support could be offered to the diagnostician. Furthermore, the name quiz function for a bronchial orifice was provided as the educational tool.(3)ConclusionEstablished system will be useful in the following situations.1.Teaching resource to study on bronchial anatomy in medical education.2.Teaching Materials of bronchoscopy in bed side learning for medical student3.Teaching materials of virtual reality in Medicine and of Intellectual Diagnostic Imaging Support4.Skill up tool of bronchoscopy for doctors in training.5.Informed consent sake for the patient and his family6.Pre-bronchoscopic virtual examination for the safe and smooth examination for better patient careThe virtual bronchoscopy by the volume rendering method could be developed as a diagnostic support system of the next generation.
