项目摘要

The goal of this research is to improve the accuracy of neurosurgery through feeding back the typographical information to surgeons. The real time typographical information was expected to display on a three-dimensional computer graphic imaging. This research was intended to ameliorate the neuronavigator system using three-dimensional digitizer developed from 1985 to 1986. The points of this study were as follows; first, investigation to detect topographical information using ultrasound (US) generator and receivers. Second, display of three-dimensional brain image reconstructed from CT images inputted from tv camera. The topographical information and the brain image was integrated.As results of trial, detection of points using us probe was very difficult, if it was applied extracranially. However, the detection of vascular component was possible using doppler method and the information was applicable in surgery. Three-dimensional reconstruction form ct images was successful using a minicomputer.Finally, three-dimensional images of vascular tree were reconstructed from conventional two-plane angiogram, and combined with three-dimensional brain image from serial CT images. The improved neuronavigator system has been used for preoperative design and/or navigation for removal of deep-seated brain tumor or evacuation of intracerebral hematoma, and evaluated as very useful supportive system for neurosurgeons.

这项研究的目标是通过将印刷信息反馈给外科医生来提高神经外科手术的准确性。实时印刷信息预计将显示在三维计算机图形成像上。本研究旨在利用1985年至1986年开发的三维数字化仪改进神经导航系统。本研究的要点如下：首先，使用超声波（美国）发生器和接收器进行调查以检测地形信息。其次，显示根据电视摄像机输入的CT图像重建的三维脑图像。地形信息和大脑图像被整合。试验结果表明，如果应用于颅外，使用美国探针检测点是非常困难的。然而，使用多普勒方法可以检测血管成分，并且该信息适用于手术。利用小型机成功实现了CT图像的三维重建。最后，根据传统的二维血管造影重建血管树的三维图像，并与连续CT图像的三维脑部图像相结合。改进的神经导航系统已用于术前设计和/或导航，以切除深部脑肿瘤或清除脑内血肿，并被评价为对神经外科医生非常有用的支持系统。
