Biomagnetic field measuring apparatus

摘要

A biomagnetic field measuring apparatus including: a plurality of magnetometers each employing a superconducting quantum interference device for measuring the magnetic field generated from an organism; a unit for calculating a pseudo-current from a normal component of the magnetic field; a unit for calculating the pseudo-current from the magnetic field obtained from the plurality of magnetometers to integrate the pseudo-current in a fixed direction on the circumference at a fixed distance from each of the associated ones of the sensors; a unit for calculating a maximum value or a minimum value of the integral value obtained by the unit for performing the integral; and a unit for calculating a difference value between the absolute value of the maximum value and the absolute value of the minimum value.
