摘要： The sensitivity in detection in a depth direction of a living body and the overall signal-to-noise ratio of an apparatus are improved, whereby a distribution of current sources in the living body or a plurality of current dipoles can be inferred more accurately than they conventionally are. A pickup coil array is made by combining a plurality of types of pickup coils that are mutually different in at least one of the order of a differential and a base line. The plurality of types of pickup coils are mutually different in, for example, only the order of a differential or only a base line, and are arranged separately at different measurement points or arranged at the same measurement point. Included is a magnetic source inferring means for inferably computing information on magnetic sources in a living body or information on the distribution of magnetic sources on the basis of detection signals provided by the plurality of types of pickup coils. The magnetic source inferring means includes a means for compensating for the influence of magnetic crosstalk among the plurality of types of pickup coils.

摘要： Flux of magnetic field generated from an object P of magnetic measurement, which links with the pick-up coils of the fluxmeters, where the flux is converted into electrical signals by each of the SQUID chips driven by the FLL circuits. The electrical signals are sent to the data collection unit via the signal processing circuit. In the data collection unit, the electrical signals are converted into digital data by the A/D converter. The converted digital data are recorded on a hard disk or a magnet-optical disk or the like, of the data recording section. The digital data recorded on the data recording medium are compensated with use of a crosstalk compensation matrix so as to remove the interference due to crosstalk for each channel, by the crosstalk compensation section. The compensated data are displayed directly on the display in the form of a magnetic field distribution or time waveform, and sent to the data analysis section. The data sent to the data analysis section are subjected to a process for obtaining a current source distribution of the living body or the like, and then displayed on the display.
