This article discusses the evolution of our stereotactic system which evolved from the commercially available Todd-Wells stereotactic instrument. The Todd-Wells frame was originally designed for radiographically based, functional neurosurgical procedures. We modified it for computed tomography compatibility and later devised localization systems for magnetic resonance imaging and digital angiography. Based on the limitations in the original design applying to our own set of requirements, including tumor stereotaxis, we totally redesigned the system around the arc-quadrant principle of the original Todd-Wells instrument. While this intermediate system was being used in our surgical practice, further limitations were noted and corrected in the system we presently use. The present stereotactic frame is completely interactive with an operating room computer system.
本文讨论了我们的立体定向系统的演变，该系统是从市售的托德-韦尔斯立体定向仪器发展而来的。托德-韦尔斯框架最初是为基于放射成像的功能性神经外科手术设计的。我们对其进行了修改以使其与计算机断层扫描兼容，后来又设计了用于磁共振成像和数字血管造影的定位系统。基于原始设计中适用于我们自己的一系列要求（包括肿瘤立体定向）的局限性，我们围绕原始托德-韦尔斯仪器的弧象限原理对系统进行了全面重新设计。当这个中间系统在我们的外科手术实践中使用时，我们注意到了该系统的进一步局限性并进行了修正。目前的立体定向框架与手术室计算机系统完全交互。
