MRI Smart Amplifier

The EEG100C-MRI Electroencephalogram (EEG) Amplifier amplifies bioelectric potentials associated with neuronal activity of the brain and can be used to perform unipolar or bipolar EEG measurements. The amplifier output can be switched between normal EEG output and Alpha wave detection. The Alpha detection mode outputs a smoothed wave with a peak indicating maximal alpha activity (signal energy in the 8-13 Hz frequency range).

Use the AcqKnowledge software to automatically filter the raw EEG signals for Alpha, Beta, Theta, and Gamma wave activity and to provide a full frequency analysis of the data. The software will also remove any EOG artifact in the signals.

The EEG100C-MRI amplifier should be used with the MECMRI-BIOP MRI cable/filter set. The EEG100C-MRI is part of a complete research system, interfacing with the MP160/MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications and supporting acquisition of a broad range of signals and measurements.

Compatibility


MRI Use: Conditional to 7T

Condition: EEG100C-MRI Amplifier stays in the Control Room and is used with the MECMRI-BIOP filtered cable set and recommended MR leads/electrodes/transducers; tested to 7T.

IMPORTANT!  See Safety Guidelines for recording  biopotential measurements in the MRI environment.

Features:

  1. Less sensitivity to electrode and transducer lead placement
  2. Improved gain selectability
  3. No missing spectra in physiological signal frequency band
  4. Minimizes computer-based real-time or post-processing signal processing
  5. Cleaner data available as real-time analog output

The MRI Smart Amplifiers incorporate advanced signal processing circuitry which removes spurious MRI artifact from the source physiological data. Signal processors are able to distinguish between physiological signal and MRI artifact as manifested by gradient switching during MRI sequences, such as Shim or EPI.

Because MRI-related transient artifact is removed at the source, the MRI version amplifier can be sampled at the same rate as during normal (non-MRI) physiological recording. In every aspect, data recording is easier and the final results are cleaner when using the MRI version amplifiers to record physiological data in the fMRI or MRI.
