Patent ID: 8010178

Claim:
A biomagnetic field measurement apparatus comprising: a gate-type first support including two leg parts and a coupling part coupling upper parts of the two leg parts; a first and a second cylindrical cryostats disposed side by side between the two leg parts and under the coupling part; a first and a second pick-up sensors configured to detect biomagnetic fields, the first and the second pick-up sensors being disposed in mirror symmetric locations, the first and the second pick-up sensors being incorporated in the first and second cryostats, respectively, and at least a part of the each pick-up sensor being protruded from a side face of a respective cylindrical cryostat; a second support supported by the first support and configured to drive the two cryostats in an axis direction of the cryostats; a third support supported by the second support and configured to drive the cryostats in directions along the coupling part; a fourth support supported by the third support and configured to drive each cryostat to rotate around a respective axis of each cryostat; drive elements configured to drive, respectively, the second to fourth supports; and a controller configured to control the drive elements.
