摘要：<P>PROBLEM TO BE SOLVED: To provide a living body magnetic field measuring device which can quantify a transmission process of electrophysiological agitation. <P>SOLUTION: The living body magnetic field measuring device is composed of two or more SQUID fluxmeters which measure a living body magnetic field generated from a living body, living body signal measuring devices 6 and 7 which measure and collect living body signals generated periodically, an arithmetic processing unit 10 which computes living body magnetic field signals and living body signals measured simultaneously as pairs from two or more directions, and a display unit 11 which indicates the result of arithmetic processing. Thereby, the change of agitation with time can be grasped in detail using a small number of maps without estimating an origin of magnetic field and displaying a lot of equal magnetic field diagrams. <P>COPYRIGHT: (C)2004,JPO
