Patent ID: 7668581

Claim:
A biomagnetic measurement apparatus, comprising: a plurality of magnetic field sensors disposed two-dimensionally to detect a magnetic field from an inspection object respectively; an arithmetic processing unit for collecting said magnetic fields to be measured from first and second directions of said inspection object to process their data arithmetically; and a display device for displaying a result of said arithmetic processing, wherein said arithmetic processing is executed to convert each of the positions of said plurality of magnetic field sensors to polar coordinates represented by a radius vector r and an oblique angle respectively within a first range in which said oblique angle θ is 0°<θ<180° when detecting said magnetic fields from said first direction and each of the positions of said plurality of magnetic field sensors to polar coordinates within a second range in which said oblique angle θ is 180°<θ<360° when detecting said magnetic fields from said second direction, then set said first magnetic field data to correspond to said polar coordinates within said first range and said second magnetic field data to correspond to said polar coordinates within said second range, and combine data of said first and second magnetic fields to obtain data of a third magnetic field at polar coordinates within a third range in which said oblique angle θ is θ=0° and θ=180°.
