Magnetoencephalography System and Method for 3D Localization and Tracking of Electrical Activity in Brain

A magnetoencephalogram (MEG) system is provided for use with a head. The MEG system includes a shell, and three three-axis gradiometers and a computing portion. Each three-axis gradiometer detects a magnetic field vector from a magnetic dipole in the head and generates a respective detected signal b...

Summary:A magnetoencephalogram (MEG) system is provided for use with a head. The MEG system includes a shell, and three three-axis gradiometers and a computing portion. Each three-axis gradiometer detects a magnetic field vector from a magnetic dipole in the head and generates a respective detected signal based on the respective magnetic field vector. Each three-axis gradiometer is disposed at a respective position of the shell. The computing portion determines a location of the magnetic dipole based on the first detected signal, the second detected signal and the third detected signal.
