Systems have also been built for many other fields of interest, including for geophysical and military applications. These devices detect minute magnetic fields and are particularly useful in brain scanning procedures.
Major markets are in Japan, Europe and North America.
Unlike other functional brain imaging technologies, MEG systems are completely noninvasive and pose absolutely no risk to the patient. MEG may be used for pre-surgical functional mapping, assessment of pathological functional deficits, neuropharmacological investigations, trauma assessment, epileptic assessment, and a growing list of research investigations in neuroscience and psychiatry. The first MEG system using a shielded room was operated at the Francis Bitter Magnetic Laboratory at MIT for many years. It was under the direction of group leader David Cohen, a pioneer in the field of magnetoencephalography. Dr. Cohen, who is considered the inventor of the MEG system, first measured the magnetoencephalogram in 1968.
