The non-invasive measurement of biomagnetic signals from the human nervous system has seen widespread clinical implementation since the first electrocardiogram (MCG) recording in the early 1960s. Shortly after, highly sensitive SQUID (Superconducting Quantum Interference Device) magnetometers allowed for direct monitoring of magnetic activity from the brain (magnetoencephalography, MEG).
The use of these traditional magnetometry technologies has limitations, including, but not limited to cryogenic requirements, the need for environmental magnetic noise removal, and resolving the magnetic inverse problem. These limitations have led to ongoing research and development of improved magnetic sensors, going beyond the SQUIDs technology (like atomic magnetometers, optically pumped magnetometers) resulting in evolution of MCG and MEG machines. Additionally, since the turn of the century, the field has seen the emergence of magnetoneurography/magnetospinography (MNG/MSG) that can measure weak magnetic fields caused by neural activity in the spinal cord and peripheral nerves, as well as magnetomyography (MMG) which measures weak magnetic fields in the muscles.
In this Research Topic for Frontiers in Medical Technology, we seek to highlight the technological development and advancement of magnetometry devices (MCG, MEG, MSG/MNG, & MMG) and related magnetic sensors. We welcome contributions that examine the historical development of these existing technologies, emerging magnetometry devices and sensors (quantum, atomic, optical) and perspectives for future clinical applications of recording biomagnetic signals from the human nervous system.
Original Research articles are encouraged, but other article types (Reviews, Mini Reviews, Opinion, Hypothesis & Theory, etc.) are also welcome.
