项目摘要

A new system was invented as the simplification for computer tomography (CT) guided stereotaxic neurosurgery. The system is composed of multi-joint three dimensional digitizer and microcomputer. CT was performed preoperatively with three standard makers placed on nasion and bilateral ears. At surgery, after getting the fixation angle of the head of the patients by sampling the standard points, the system translated the position of the tip of the digitizer onto the CT images displayed on computer display. This system have an unique feature that allows introducing the idea of CT guided stereotaxis into the conventional neurosurgery through a craniotomy which could not be achieved hitherto developed CT-guided stereotaxic apprati and operator is able to know where he is operating now referring brain database stored in a floppy disk. This system was very useful to improve the neurosurgical operations.

一种新的系统被发明作为计算机断层扫描（CT）引导的立体定向神经外科手术的简化。该系统由多关节三维数字化仪和微型计算机组成。术前在鼻根和双侧耳上放置三个标准标记物进行CT检查。在手术中，通过标准点采样获得患者头部的固定角度后，系统将数字化仪尖端的位置转换到计算机显示器上显示的CT图像上。该系统具有独特的功能，允许通过开颅手术将CT引导立体定位的想法引入到传统的神经外科手术中，这是迄今为止开发的CT引导立体定位设备无法实现的，并且操作者能够知道他现在正在操作的位置，参考存储在软盘中的大脑数据库。该系统对提高神经外科手术质量具有重要意义。
