MAGNETOENCEPHALOGRAPHY DEVICE AND METHOD OF USING THE SAME

摘要

It is possible to provide a magnetoencephalography device having a low noise and a high sensitivity. When installing on a floor the magnetoencephalography device using a high-temperature superconductor magnetic shield device, anti-vibration means is provided to eliminate generation of a noise and to eliminate relative movement between the high-temperature superconductor magnetic shield and an SQUID fluxmeter. Even if an inevitable small vibration is caused, the fluctuation component detected by the SQUID fluxmeter is not generated from static magnetism trapped.
