项目摘要

Three-dimensional (3D) images of the pelvic structure have been shown useful to apprehend pre- and postoperative anatomical state stereoscopically of the patients with anorectal malformation. Based upon accumulated knowledge and 3D anatomical consideration, we had had started developing surgical simulation softwares. The purpose of the research was to obtain three-dimensional image data of the pelvic structure of the patients with anorectal malformation based upon X-ray CT or MRI and to apply computer graphic techniques such as virtual reality processings to develope a useful surgical simulation softwares. In developing a useful computerized surgical simulation system, it is indispensable for program engineers and surgeons to collaborate intimately. Such collaboration would necessitate image processings which are requested from the surgeon's point of view. Thus the research was carried out by communicating with each other using internet by transferring data files and program files.In 1997, collaborateing system was established between schools by communicating via Internet and the clinical considerations and preliminary results were published. In 1998, surgical simulation softwares which work in personal computers for patients with congenital anorectal disease were developed with close consultations between progranmers and a surgeon. In the program developed. image processings useful for surgery which include improving images by rendering, removing or cutting tissues for the surgical simulation were achiebved. In terms of applying the virtual reality techniques, basic image processing was attempted but the computer's power hindered applying the technique for clinical settings, which is considered to be the next goal to be achieved.

骨盆结构的三维（3D）图像已被证明有助于了解肛肠畸形患者的术前和术后立体解剖状态。基于积累的知识和三维解剖学的考虑，我们已经开始开发手术模拟软件。本研究的目的是基于x线CT或MRI获取肛肠畸形患者盆腔结构的三维图像数据，并应用虚拟现实处理等计算机图形技术开发实用的手术模拟软件。在开发一个有用的计算机外科模拟系统时，程序工程师和外科医生的密切合作是必不可少的。这种合作将需要从外科医生的角度要求的图像处理。因此，研究是通过互联网相互通信，通过传输数据文件和程序文件来进行的。1997年，通过互联网建立了学校间的协作系统，并发表了临床考虑和初步结果。1998年，在程序员和外科医生的密切协商下，在个人电脑上为先天性肛肠疾病患者开发了手术模拟软件。在程序开发。实现了对外科手术有用的图像处理，包括通过渲染、移除或切割用于外科模拟的组织来改善图像。在应用虚拟现实技术方面，尝试了基本的图像处理，但计算机的能力阻碍了该技术在临床环境中的应用，这被认为是下一个要实现的目标。
