A
Neuroscan tem o prazer de apresentar o sistema patenteado
MagLink
para registros de EEG e ERP integrados para gravações dentro do
fMRI. Este sistema da 2ª geração melhora o sistema original
Opti-Link, aumentando a largura das bandas e eliminando a ligação
óptica e o pré-amplificador. O sistama
MagLink
fornece a capacidade de registrar durante a seqüência de pulsos
mantendo a integridade dos dados de EEG. |

The patented** fMRI compatible
electrode and electrode placement technique employing a carbon fiber
technology ensures that the MagLink has negligable impact on MR
signal quality, enabling the simultaneous acquistion of
uncompromised fMRI and EEG data.
The gradient artifact that is injected into the EEG data can be
reduced by a number of different strategies that are included in the SCAN software.
Having a variety of data processing methods available is critical to
account for the different artifacts that are encountered. The
individual artifact signatures vary based on the type of pulse
sequence, magnet type and strength, the electrode impedance, even
the quality of the shim on a particular day. Neuroscan"s correction
methods can correct the EEG data under a variety of parameters.
The most recent development affecting gradient artifact reduction
derives from the ability to synchronize the clocks between the
amplifiers and the MRI Scanner. Clock synchronization improves the
accuracy of gradient artifact reduction, simplifies the artifact
reduction process and allows acquisition using standard sampling
rates (e.g., 500 Hz), click HERE for more information about clock
synchronization.
The complete MagLink system consists of MagLink Cables, MagLink Caps,
a Neuroscan amplifier and the SCAN software. This fully functional
system has acquired EEG and fMRI data successful in the following
magnets:
GE Signa 1.5 Tesla
GE Signa 3.0 Tesla
Siemens 1.5 Tesla
Siemens 3.0 Tesla
Philips 1.5 Tesla
Varian 4.0 Tesla |
