作者们使用两个独立且同时运行的无自旋交换弛豫铷磁力仪检测到了来自人脑的磁场。通过位于头部两侧的两个多通道磁力仪记录了多名受试者在听觉刺激下的诱发反应。利用多通道测量所实现的信号处理技术来提高信号质量。这是多传感器原子磁力仪脑磁图的首次展示,并为开发一种用于源定位的非低温全头脑磁图阵列提供了框架。
The authors have detected magnetic fields from the human brain with two independent, simultaneously operating rubidium spin-exchange-relaxation-free magnetometers. Evoked responses from auditory stimulation were recorded from multiple subjects with two multi-channel magnetometers located on opposite sides of the head. Signal processing techniques enabled by multi-channel measurements were used to improve signal quality. This is the first demonstration of multi-sensor atomic magnetometer magnetoencephalography and provides a framework for developing a non-cryogenic, whole-head magnetoencephalography array for source localization.
