Abstract
An estimated current dipole displaying system in which a weak magnetic field generated from the heart or brain is measured to estimate the position, direction, magnitude and depth from a body surface of a current dipole which is equivalent to a heart current or a current flowing in a nerve and the estimated current dipole is displayed on a two-dimensional display. A parameter, other than that used to indicate the magnitude and those inappropriate for combined use with the magnitude indicating parameter, is used as a depth indicating parameter and the current dipole is thus displayed.
