Abstract:

As a cutting-edge field of quantum precision measurement, ultra-weak magnetic field measurement technology holds revolutionary potential for medical diagnosis. Its core lies in utilizing ultra-high-sensitivity sensors such as atomic magnetometers to detect extremely weak magnetic field signals (e.g., brain magnetic fields only about 10⁻¹⁵~10⁻¹³ Tesla) generated by human electrophysiological activities. Current research focuses on breaking through environmental noise shielding, developing wearable array systems, and integrating advanced algorithms to achieve precise magnetic source imaging. In medical applications, it is expected to achieve pioneering clinical breakthroughs in areas such as quantitative assessment of myocardial and brain function, facilitating the early, rapid, and accurate diagnosis of major diseases. In the future, this technology will advance towards device miniaturization and cost reduction, striving to transition from top-tier laboratories to ordinary hospitals, and ultimately become an important diagnostic tool for human functional information imaging, ushering in a new era of ultra-early disease detection and precise diagnosis and treatment.
