We describe a computer program for stereotactic surgery planning based on multimodality imaging and the display of intracranial EEG data in relation to anatomical data. The program is primarily designed to be used by surgeons to assist them in localizing brain structures and plan the safe and accurate insertion of surgical tools and depth electrodes. The mathematics underlying these concepts are briefly described. Estimates of the accuracy of the procedures are calculated and made available to the user. An extension of the program was developed to integrate intracranial EEG data with conventional images in order to help the neurologist and neurosurgeon in visualizing the EEG data in relation to the anatomy. It can be used to visualize the measured EEG voltages, or processed signals such as the application of the tetrahedral field calculation, which provides an extension of conventional bipolar EEG to 3 dimensions.
我们描述了一种基于多模态成像以及颅内脑电图（EEG）数据与解剖数据相关显示的立体定向手术规划计算机程序。该程序主要供外科医生使用，以协助他们定位脑结构，并规划手术工具和深度电极的安全准确插入。简要描述了这些概念背后的数学原理。计算了这些程序的准确性估计值并提供给用户。该程序的一个扩展版本被开发出来，用于将颅内EEG数据与传统图像整合，以帮助神经科医生和神经外科医生直观地了解EEG数据与解剖结构的关系。它可用于可视化测量的EEG电压，或诸如应用四面体场计算等处理后的信号，这将传统双极EEG扩展到了三维。
