<P>PROBLEM TO BE SOLVED: To suitably reduce the noise of measuring data in the measurement of a cerebral magnetic field or the like. <P>SOLUTION: The noise of the measuring data is reduced by employing a measuring step S1 for measuring a magnetic field caused by an ion current flowing accompanied by the nerval activity of a brain over a plurality of measuring chances using a field measuring means for a plurality of channels, a reverse problem estimating step S2 for regarding the measuring data in a plurality of the measuring chances obtained in the measuring step as measuring data obtained with respect to different channels in one measuring chance and estimating a parameter which prescribes a predetermined phenomenon from the measuring data by solving a linear inverse problem and a regular problem estimating step S3 for estimating the magnetic field measured in a required channel by solving a linear regular problem. <P>COPYRIGHT: (C)2004,JPO |
