History
CTF MEGTM technology began its development in 1970.
In those early years the underlying SQUID technology was employed in applications for geophysical exploration
and non-destructive materials testing. Later, CTF engineers and physicists (under contract with
the Canadian Department of National Defence) developed airborne submarine detection instrumentation.
This technology was eventually incorporated into the world leading
CTF magnetoencephalography (MEG) family of medical devices.
From this foundation of outstanding technical achievement, the CTF MEGTM technology
has continued to improve the capabilities of pioneering researchers and leading clinicians in
the exploration and treatment of the human brain.
Since 2007, CTF MEGTM instruments have been serviced and manufactured by MEG International
Services Ltd. (MISL). In 2009, MISL acquired the assets of 4D Neuroimaging (San Diego, CA) and
continues to offer service and support to 4D customers throughout the world.
