Outline of Final Research Achievements

Magnetospino/cardiography (MSCG) detects weak magnetic fields accompanied with neural or muscular activity on the body surface. The MSCG is a noninvasive electrophysiological testing. Therefore, it can be applied to healthy subjects for risk evaluation of the spinal or heart diseases. To establish the risk evaluation criteria, huge amount of the MSCG data from healthy subjects must be corrected and long term follow-up is necessary. In this study, we advanced the development of the MSCG system from three aspects, improvements of robustness by the low-frequency-band noise reduction named DOLPHIN and DSSP, running cost reduction by introducing of closed-cycle helium recondensing, and modification of the software user interface and the data acquisition system to improve usabilities.
We also investigated new clinical applications of the MSCG. One of the results was the noninvasive detection of rotor activity during atrial fibrillation focusing on the tangential components of the MCG signals.
