## Description

- description: ダイヤモンド量子マグネトメーターを用いて、生体磁気センシングにおける実用的な測定の観点から、高感度約6 pT/√Hzの性能を評価しました。乾式ファントムは、脳活動によって生成される等価電流双極子（ECD）を表し、脳磁場を模倣します。このマグネトメーターの空間分解能は、脳磁場分布の変化の長さよりも十分に高いと評価されました。最小検出可能なECDモーメントは、ECDから2.4
    mm離れた距離で約8000回の測定を平均化することで0.2 nA・mと評価されます。また、ヒトの脳磁場測定におけるECDの検出可能性についても検討しました。結論として、一次体性感覚野のような浅い皮質領域からの脳磁場を検出することは可能だと考えられます。
