A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography . The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.
Magnetoencephalography is a biomedical imaging technique used for mapping brain activity by recording magnetic fields produced by the naturally occurring electrical currents generated by neurons in the brain, using very sensitive magnetometers. Currently, MEG requires a magnetically shielded room for operation. Achieving MEG that works in normal environments, without the need for magnetic shielding, is a major goal.
Building upon this technology, a team of researchers from Japan, led by Associate Professor Naota Sekiguchi from the Department of Electrical and Electronic Engineering at Tokyo Institute of Technology, recently developed a novel and sensitive diamond quantum magnetometer."Clinically acceptable MEG requires sensitivities, at least, in the order of picotesla in the near-dc frequency range of 5-100 Hz within a reasonable measurement time.
Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers ...
