Abstract

An accessory locating device to the existing BRW stereotactic system is presented. It can be used as a reference device to locate angiographic data with respect to the BRW stereotactic system. Hence, the projection of target points onto angiograms, visible on CT scans, are easily calculated, as well as the stereotactic coordinates of a set of points (e.g., AVM) indicated on at least two angiograms. As a final result integrated images of cerebral blood vessels and an outline of tumor lesions can be generated using more sophisticated computer equipment.

摘要

本文介绍了一种用于现有BRW立体定向系统的辅助定位装置。它可作为一种参考装置，用于相对于BRW立体定向系统定位血管造影数据。因此，目标点在CT扫描可见的血管造影上的投影很容易计算出来，以及至少两张血管造影上所示的一组点（如动静脉畸形）的立体定向坐标也能算出。最终，使用更先进的计算机设备可以生成脑血管的整合图像和肿瘤病变轮廓。
