摘要： Magnetism generated in the cervical or waist part of a subject is measured without the neck or waist of the subject being bent forward. A sensor cylinder is arranged to have a four-sided cylindrical shape. One side at the distal end of the sensor cylinder is moderately curved. This allows the side at the distal end of the sensor cylinder to come into direct contact with the cervical or waist part of the subject when the neck or waist remains not belt forward, whereby a faint magnetism generated in the spinal cords or nerves of the subject can favorably be measured.

摘要： A biomagnetism measurement apparatus includes a memory and a processor configured to set a curved surface as a region-of-interest based on a morphological image including a portion to be evaluated of a subject, the morphological image being acquired by an image acquisition apparatus, and the curved surface being a surface on which an anterior-posterior position of the subject changes in a cranial-caudal direction and in a left-right direction along a position of a nerve to be evaluated. The processor is further configured to estimate current distribution in the region-of-interest based on magnetic data, the magnetic data being acquired by measuring a magnetic field with a magnetic measurement instrument, and the magnetic field being generated by an electrical activity of a nerve in the portion to be evaluated.

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.
