An image analysis system was developed for stereotactic neurosurgery that allows the simultaneous display of brain images from different imaging devices obtained in different orientations. The system is based on a stereotactic frame and a microcomputer and features an easy user interface together with point registration and region of interest analysis in three-dimensional space. A dynamic multi-image environment allows for simultaneous display of magnetic resonance, computed tomography, digital subtraction angiography, and positron emission tomography images in multiple windows, adjusted for common coordinates with reference to stereotactic frame fiducial markers. Linkages between images allow information interchange between different modalities and different views: Points and regions defined in one image can be transferred to others, and cursor coordinates in one image can be calculated and dynamically projected in other images. Phantom studies show that the system distortions are minor and that the system is suitable for clinical use. The system provides exceptional advantages over previous imaging procedures for stereotactic surgery.
开发了一种用于立体定向神经外科手术的图像分析系统，该系统能够同时显示从不同成像设备以不同方向获取的脑部图像。该系统基于立体定向框架和微型计算机，具有易于使用的用户界面，以及在三维空间中的点配准和感兴趣区域分析功能。动态多图像环境允许在多个窗口中同时显示磁共振、计算机断层扫描、数字减影血管造影和正电子发射断层扫描图像，并根据立体定向框架基准标记调整为通用坐标。图像之间的链接允许不同模态和不同视图之间进行信息交换：在一个图像中定义的点和区域可以转移到其他图像，并且一个图像中的光标坐标可以计算并动态投影到其他图像中。模型研究表明，该系统的畸变较小，适用于临床使用。该系统相对于以前的立体定向手术成像程序具有显著优势。
