For more than 25 years, CTF MEG has been the performance leader in MEG instrumentation for superior measurement of human brain function. CTF MEG instruments combined with robust CTF SQUID sensor technology, noise suppression methods, and instrument engineering have a well-earned reputation as the highest performing MEG systems available.

CTF MEG 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 MEG technology has continued to improve the capabilities of pioneering researchers and leading clinicians in the exploration and treatment of the human brain.

In 2009, CTF acquired the assets of 4D Neuroimaging (San Diego, CA) and continues to offer service and support to 4D customers throughout the world.
