摘要： A bioelectric current estimation method includes acquiring position information of a nerve in a measurement target region of a subject for which magnetic data is measured with a magnetic sensor, the position information of the nerve being acquired based on a nerve image included in a morphological image of the measurement target region; acquiring a positional relationship between a position of the nerve and a position of the magnetic sensor, based on the acquired position information of the nerve and position information of the magnetic sensor when the magnetic sensor is positioned to face the measurement target region; and estimating a neural activity current, which is generated in association with neural activity of the subject, based on the acquired positional relationship and the magnetic data of the measurement target region measured by the magnetic sensor.

摘要： An information acquisition method includes: executing a voxel defining process to divide an area in which a signal source is assumed to be present and define a voxel division V1 specifying resolution of an image; executing a data collecting process to acquire magnetic field data resulting from measurement of a magnetic field generated in the area; and executing a reconstructing process to estimate, by using a mathematical algorithm, a direction and strength of a current of a signal source at a location of each voxel based on the acquired magnetic field data. The reconstructing process includes: calculating a Gram matrix by using a voxel division V2 defined coarser than the voxel division V1; and reconstructing, by using the Gram matrix, a direction and strength of a current of a signal source in the voxel division V1.
