Abstract
A biomagnetic field measurement apparatus comprises, a plurality of magnetometers each having a SQUID sensor and a detection coil and each detecting a magnetic field generated from a heart of a fetus in a mother; a processor processing magnetic field wave forms detected by the magnetometers; and a display displaying results obtained by the processor. The processor estimates a position of a current dipole from the magnetic field wave forms, and processes projecting the position of the current dipole on a first plane parallel to a plane on which one ends of the magnetometers are disposed on processes projecting the position of the current dipole on a second plane perpendicular to the plane on which the one ends of the magnetometers are disposed. The position of the current dipole projected on the first plane and the position of the current dipole projected on the second plane are displayed on the display.
