  • Biomagnetic measurement system and biomagnetic measurement method
    Patent number: 11389076
    Abstract: A biomagnetic measurement system includes a magnetism measurement apparatus configured to measure a magnetism of a target; and an electrical stimulation apparatus configured to apply a stimulation current to the target. The magnetism measurement apparatus includes a confirming unit configured to confirm a magnitude of an artifact caused by the stimulation current. The electrical stimulation apparatus is configured to output a compensation current for reducing the artifact after the stimulation current is output, based on information from the confirming unit.
