Abstract
A biomagnetic field measuring apparatus includes a plurality of SQUID magneto-meters for measuring a biomagnetic field generated from a living body, living-body signal measuring devices and for measuring and collecting living-body signals generated periodically, an operation processing device for operation processing the biomagnetic field signal and the living-body signal measured simultaneously as pairs in a plurality of directions, and a display unit for displaying a result of the operation processing. Change in time of excitation can be grasped in detail by using a small number of maps without presumption of a magnetic field source and display of many iso-magnetic field maps.
