Abstract

We developed a multichannel system based on superconducting quantum interference devices (SQUIDs) for magnetoencephalography measurements. Our system consists of 163 fully-integrated SQUID magnetometers, 154 channels and 9 references, and all of the operations are performed inside a magnetically-shielded room. The system exhibits a magnetic field noise spectral density of approximatively 5 fT/Hz(1=2). The presented magnetoencephalography is the first system working in a clinical environment in Italy.

摘要

我们开发了一种基于超导量子干涉器件（SQUID）的多通道系统用于脑磁图测量。我们的系统由163个完全集成的SQUID磁力计、154个通道和9个参考通道组成，所有操作均在磁屏蔽室内进行。该系统的磁场噪声谱密度约为5 fT/Hz(1=2)。所展示的脑磁图系统是意大利首个在临床环境中运行的系统。
