摘要

生物体产生的生物磁场信号携带有重要的生物电生理和病理信息,通常用超导量子干涉器件探测这些生物磁。随着原子磁力计发展到飞特斯拉水平,作为一种超灵敏磁场探测器,超灵敏原子磁力计在生物磁的测量和研究中扮演一个非常重要的角色。简要介绍了生物磁场信号来源及其特性,超灵敏原子磁力计的物理机制和分类,以及超灵敏原子磁力计在心磁、脑磁和神经科学等生物磁场测量领域的应用,展望了超灵敏原子磁力计在生物医学领域的应用与发展。

Abstract

Biomagnetic fields produced by organisms carry valuable informations of electrophysiologies and pathologies, which are commonly detected by superconducting quantum interference device. As an ultra-sensitive magnetic field detector with the sensitivity of femtotesla level, the ultra-sensitive atomic magnetometer plays an important role in detection and study of biomagnetism. We introduce the sources and characteristics of biological magnetic field signals, as well as the physical mechanism and classification of ultra-sensitive atomic magnetometers. We also summarize and forecast the applications of ultra-sensitive atomic magnetometers in the field of the biomagnetic field detection, such as magnetocardiography, magnetoencephalography, and neurosciences.
