Résumé

The electrical activity of the human heart and brain are noninvasively visualised and analysed using a multi-channel superconducting quantum interference device (SQUID) system. Multi-channel SQUID systems for magneto-cardiogram and magneto-encephalogram procedures have been developed by improving SQUID and cryogenic technology. Recently, the author has developed two types of biomagnetic systems. The SQUID system, which utilizes a low-temperature superconductor (LTS) SQUID, is capable of detecting very weak signals. A high-temperature superconductor (HTS) SQUID device system is under development as a next-generation product. The device system is designed to save space and provide mobility for the overall system, including the magnetically shielded cylinder. Due to an improvement in HTS-SQUID sensitivity and the introduction of a noise reduction technique, the real-time measurement of cardio-magnetic fields has become feasible.
