Elekta Neuromag Vector View 306 channel MEG //
This 306 channel MEG system is comprised of 204 planar gradiometers and 102 magnetometers and is capable of collecting up to 128 channels of simultaneous EEG data at up to 5 kHz sampling frequency. The planar gradiometers provide sensitivity to sources close to the sensor array whereas the magnetometers provide sensitivity to distant sources, including sources originating from the small head of a child. This provides additional advantages over previous gradiometer-only systems. This system has 24 bit A/D conversion providing the largest dynamic range of currently-available MEG systems.
The Elekta Neuromag also comes with specialized software that provides real-time head movement correction allowing for even relatively large head movements within the sensor array without loss of spatial resolution. The same software also provides novel artifact rejection methods, allowing for data collection from a wide range of patient populations - including pediatric patients and epilepsy patients with implanted vagal nerve stimulators.
