<P>PROBLEM TO BE SOLVED: To provide a biomagnetism measuring apparatus capable of easily detecting brain magnetic field with higher sensitivity than usual, more practically, easily closing the sensor surface to the head surface of a test subject by coupling two independent cryostats while keeping the enantiomeric composition, and detecting the brain magnetic field of right and left brains with high sensitivity at the same time. <P>SOLUTION: This biomagnetism measuring apparatus has two independent cryostats which hold a SQUID fluxmeter and are mounted to be in enantiomeric composition. These two cryostats move together from right to left or up and down and rotate during the enantiomeric composition. The gantry holding cryostats is a portal type with the consideration to suppress the vibration of cryostats. <P>COPYRIGHT: (C)2008,JPO&INPIT |
