The demands on virtual planning systems are increasing, particularly for technically pretentious surgical interventions such as intracranial endoscopy. In this article, a new virtual system for neuroendoscopy (VIVENDI) is presented. The main purpose of this system is to provide support for planning and training in neuroendoscopic interventions.
The software is applied for virtual endoscopic visualization of three-dimensional magnetic resonance datasets, using a clinical magnetic resonance scanner. Rendering is performed on a Hewlett-Packard UNIX workstation.
Virtual endoscopy provides a three-dimensional view of the cerebral ventricles, with good visualization of anatomic details. The rendering system used allows the generation of fly-through sequences for the entire ventricular system in real time. Navigation is controlled by mouse movements, and the visualization of the computer-generated intraventricular spaces is adapted to the characteristics of the optical endoscope.
The presented virtual neuroendoscopy system is a promising tool for planning and training in neuroendoscopic procedures. It enables these procedures to be simulated prior to surgery based on the patient's individual anatomy.
对虚拟规划系统的需求不断增加，特别是对于技术要求较高的外科手术干预，如颅内内窥镜检查。本文介绍了一种新的神经内窥镜虚拟系统（VIVENDI）。该系统的主要目的是为神经内窥镜干预的规划和训练提供支持。
使用临床磁共振扫描仪，该软件用于对三维磁共振数据集进行虚拟内窥镜可视化。渲染在惠普UNIX工作站上进行。
虚拟内窥镜提供了脑室的三维视图，能很好地显示解剖细节。所使用的渲染系统允许实时生成整个脑室系统的飞越序列。导航由鼠标移动控制，计算机生成的脑室内空间的可视化适应了光学内窥镜的特点。
所提出的虚拟神经内窥镜系统是神经内窥镜手术规划和训练的一个有前途的工具。它能够在手术前根据患者的个体解剖结构模拟这些手术。
