Title:
生体磁気計測装置および生体磁気計測システム
Document Type and Number:
Japanese Patent JP7479032
Kind Code:
B2
Abstract:
To estimate electric current distribution from biomagnetism data by specifying positional relationships between the position of a nerve and a magnetic sensor in magnetic field measurement using an ultrasonic image.SOLUTION: A biomagnetism measuring device includes: a sensor storage part for storing a magnetic sensor; a transparent plate member disposed separably on an opposed surface opposed to a detection part of the magnetic sensor in the sensor storage part; and an electric current estimation part for estimating electric current distribution in a measurement object part from biomagnetism data on the measurement object part measured by the magnetic sensor on the basis of positional relationships between the position of a nerve and the magnetic sensor obtained from position information on the nerve of the measurement object part that can be obtained by an ultrasonic probe brought into contact with the plate member with which the measurement object part comes in contact in a state that the plate member is separated from the opposed surface, and an image including the ultrasonic probe and the plate member at the time when the position information on the nerve is obtained.SELECTED DRAWING: Figure 1
