Title:
脳磁計測装置のファントム
Document Type and Number:
Japanese Patent JP3977725
Kind Code:
B2
Abstract:
To realize the phantom of a magnetoencepharogram measuring apparatus solving the point at issue that the positional instability of an electrode, the positional precision does not rise in the installation of the electrode or the like have been yielded in a conventional phantom structure and the point at issue that a distribution of a return current (distributed current, secondary current) is changed by electrolysis.
In the phantom of the magnetoencepharogram measuring apparatus wherein a simulated current dipole is fixed and arranged in a spherical conductor uniform in conductivity, the return current route of the simulated current dipole is formed of a conductive solid.
