Bioelectric current estimation method, bioelectric current estimation device and biomagnetic measurement system

摘要

PROBLEM TO BE SOLVED: To acquire a positional relationship between a sensor for measuring a biomagnetic field and a nerve by using a nerve image included in an image of a measurement target area, and estimate a nerve activity current generated by the nerve activity of a subject. do. SOLUTION: This is a bioelectric current estimation method for estimating a neural activity current generated by a subject's neural activity based on a subject's magnetic field data obtained by measurement by a magnetic sensor and a subject's neural image, and is a magnetic field. Based on the nerve image included in the morphological image of the measurement target area of the subject to be measured, the position information of the nerve in the measurement target area is acquired, and the acquired nerve position information is opposed to the measurement target area. Based on the position information of the magnetic sensor at that time, the positional relationship between the position of the nerve and the position of the magnetic sensor is acquired, and the acquired positional relationship and the measurement target region measured by the magnetic sensor It is characterized by estimating the neural activity current based on the magnetic field data.
