 Magnetoencephalography and Magnetic Source Imaging: Presurgical Localization of Epileptic Lesions and Presurgical ...
This Assessment examines the available evidence to determine whether magnetoencephalography (MEG) and/or magnetic source imaging (MSI) provide additional diagnostic information that improves the management and outcomes of patients who are being evaluated for neurosurgical treatment in two main clinical uses.
The first group includes patients being evaluated for surgical treatment of epilepsy, including those with seizures refractory to medical management.
TEC Assessments should not be construed to suggest that the Blue Cross Blue Shield Association, Kaiser Permanente Medical Care Program or the TEC Program recommends, advocates, requires, encourages, or discourages any particular treatment, procedure, or service; any particular course of treatment, procedure, or service; or the payment or non-payment of the technology or technologies evaluated.

 An Inverse Source Problem for Maxwell's Equations in Magnetoencephalography
Consider an inverse source problem for Maxwell's equations which arises in determining locations of epileptic foci in the living human brain.
The method and results are expected to find applications particularly in magnetoencephalography.

 Magnetoencephalography - Wikipedia, the free encyclopedia
Magnetoencephalography (MEG) is the measurement of the magnetic fields produced by electrical activity in the brain, usually conducted externally, using extremely sensitive devices such as SQUIDs.

 Brain scans made easy (May 2004) - News - PhysicsWeb
Magnetoencephalography (MEG) is the only technique that can directly measure neuronal activity in the brain, but it is plagued by background noise that interferes with signals from the brain itself.
Magnetic measurements of brain activity could be free from noise in the future thanks to a new helmet-like device developed by medical physicists at the Los Alamos National Laboratory in the US.
The new helmet could provide much more accurate information on brain function (P Volegov et al.

 Introduction to MEG/EEG
Magnetoencephalography (MEG) is completely noninvasive, non-hazardous technology for functional brain mapping, providing spatial discremination of 2 mm and an excellent temporal resolution on the order of 1 ms, localizing and characterizing the electrical activity of the central nervous system by measuring the associated magnetic fields emanating from the brain.
These magnetic measurements on the brain (MEG), measurements on the magnetic field of the heart (MCG), and measurements on the magnetic field of the fetal (fMEG) are carried out at CTF Systems Inc.
Every current generates a magnetic field according to the right hand rule of physics.
