Measurement of biomagnetic fields such as magnetoencephalograms (MEGs) and magnetocardiograms (MCGs) is one of the important non-invasive imaging modalities to investigate biological functions and to diagnose disease. We have developed an ultrasensitive optically-pumped atomic magnetometer for biomagnetic measurements. In this study, human MCGs were measured with a potassium atomic magnetometer. The sensitivity of the atomic magnetometer was definitively sufficient for recording of the human MCGs. The measured signals were recovered by considering the frequency characteristics of the atomic magnetometer. The activity of the human heart estimated with the MCG maps showed good agreements with those measured with SQUID magnetometers. These results demonstrated reliability and feasibility of biomagnetic measurements with optically-pumped atomic magnetometers. |
