Abstract
An apparatus for measuring bio-magnetic fields includes a plurality of magnetometers for detecting magnetic fields generated from a live body; a driving circuit for driving the magnetometers; a computer for collecting output signals of the driving circuit in the form of data representing at least one waveform of the magnetic fields generated from the live body and for performing an arithmetic processing on the data representing the waveform of magnetic fields, a display unit, and at least one signal processing circuit for processing output signals of the driving circuit. The computer further performs an arithmetic processing of first-order differentiation on the waveform of the magnetic fields in a z direction with respect to time in order to create an arrow map and a contour map. The apparatus can also detect mechanical movement which occurs as blood flows in organs and organs move.
