摘要：
A biomagnetic field measurement apparatus includes a bed which holds a subject to be inspected in a shielded room. A cryostat holds a plurality of SQUID magnetometers at low temperature. The cryostat is arranged in the shielded room and the plurality of SQUID magnetometers detect a magnetic field generated from the subject. A driving and detecting circuit drives the plurality of SQUID magnetometers and detects signals therefrom that are processed by a computer. A display that is arranged in the shielded room displays data for viewing by an operator.
