A methodology and computer program used for transposition of image-defined trajectories into stereotactic space is presented. Arc-quadrant centered stereotactic frames (Leksell, modified by us Komai) are based on the principle of aiming a target point from any entry of a formed sphere of known radius. Frames adapted isocentrically to CT gantry and parallel to the scanning plane allow interactive selection of targets and trajectories based on multiplanar reformatted images. The mathematical fundaments to calculate angle A in the coronal plane and angle B in the saggital plane based on the geometrical configuration of arc-quadrant centered stereotactic devices are presented.
本文介绍了一种用于将图像定义的轨迹转换到立体定向空间的方法和计算机程序。弧形象限中心立体定向框架（Leksell，由我们修改为Komai）基于从已知半径的成形球体的任何入口瞄准目标点的原理。与CT机架同心适配并平行于扫描平面的框架允许基于多平面重组图像交互式选择目标和轨迹。本文还介绍了基于弧形象限中心立体定向装置的几何构型计算冠状面角度A和矢状面角度B的数学基础。
