A pilot study was carried out to test the feasibility of an adjustable computerized brain atlas, adapted to the individual anatomy for localizing current dipoles by means of magnetoencephalography (MEG). The atlas can be adapted to individual computed tomography (CT) or magnetic resonance (MR) images. Position information is transferred between these imaging methods and MEG using a stereotactic technique. For this purpose, a special non-magnetic helmet was designed to be used together with the ordinary head fixation system. It seems likely that the proposed combination of the brain atlas with MEG, CT and MRI methods will become a powerful tool in exploring different brain functions.
开展了一项初步研究，以测试一种可调节的计算机化脑图谱的可行性，该图谱适用于个体解剖结构，通过脑磁图（MEG）定位电流偶极子。该图谱可适配个体计算机断层扫描（CT）或磁共振（MR）图像。使用立体定向技术在这些成像方法和MEG之间传递位置信息。为此，设计了一种特殊的非磁性头盔，以便与普通头部固定系统一起使用。脑图谱与MEG、CT和MRI方法的提议组合似乎有可能成为探索不同脑功能的有力工具。
