摘要:

脑磁图(MEG)和超低场磁共振成像(ULF MRI)是两种基于SQUID(超导量子干涉器件)传感器检测毫微微特斯拉磁场能力的方法。这些方法的组合将允许同时对人脑进行功能(MEG)和结构(ULF MRI)成像。在本文中,我们报告的第一个实现的多传感器SQUID系统设计的MEG和超低频MRI。我们提出了一个多通道图像的人手在46微特斯拉的领域,以及结果的听觉MEG测量与新系统。

英文摘要:

Magnetoencephalography (MEG) and magnetic resonance imaging at ultra-low fields (ULF MRI) are two methods based on the ability of SQUID (superconducting quantum interference device) sensors to detect femtotesla magnetic fields. Combination of these methods will allow simultaneous functional (MEG) and structural (ULF MRI) imaging of the human brain. In this paper, we report the first implementation of a multi-sensor SQUID system designed for both MEG and ULF MRI. We present a multi-channel image of a human hand obtained at 46 microtesla field, as well as results of auditory MEG measurements with the new system.
