Decades of research have shown that magnetocardiography (MCG) has the potential to improve cardiac care decisions. However, sensor and system limitations have prevented its widespread adoption in clinical practice. We report an MCG system built around an array of scalar, optically pumped magnetometers (OPMs) that effectively rejects ambient magnetic interference without magnetic shielding. We successfully used this system, in conjunction with custom hardware and noise rejection algorithms, to record magneto-cardiograms and functional magnetic field maps from 30 volunteers in a regular downtown office environment. This demonstrates the technical feasibility of deploying our device architecture at the point-of-care, a key step in making MCG usable in real-world settings.
数十年的研究表明，心磁图描记术（MCG）有潜力改善心脏护理决策。然而，传感器和系统的局限性阻碍了其在临床实践中的广泛应用。我们报告了一种围绕一系列标量光泵磁力仪（OPM）构建的MCG系统，该系统无需磁屏蔽就能有效抑制环境磁干扰。我们成功地将该系统与定制硬件和噪声抑制算法相结合，在市中心的普通办公环境中记录了30名志愿者的心磁图和功能磁场图。这证明了在护理点部署我们的设备架构的技术可行性，这是使MCG在现实环境中可用的关键一步。
