Brain topography mapping is a useful technique for the representation of electrical activity recorded on the scalp. It clarifies spatial and temporal relationships between different cortical areas. In this work we propose a system which includes several enhancements over those previously proposed, such as an optimised interpolation method and a three dimensional reconstruction of maps. This system is available in a personal computer environment. Results clearly show a superiority of the 3D representation over 2D maps obtained with different projections. The performance of this system in terms of speed and precision is comparable to that of dedicated image processing and image synthesis workstations proposed for brain mapping.
脑地形图绘制是一种用于表示头皮记录的电活动的有用技术。它阐明了不同皮质区域之间的空间和时间关系。在这项工作中，我们提出了一个系统，该系统在先前提出的系统基础上进行了多项改进，例如优化的插值方法和地图的三维重建。该系统可在个人计算机环境中使用。结果清楚地表明，三维表示优于通过不同投影获得的二维地图。该系统在速度和精度方面的性能与为脑图谱绘制而提出的专用图像处理和图像合成工作站相当。
