EMG Electromyogram Amplifier for MRI
Part #: EMG100C-MRI

MRI Smart Amplifier

The EMG100C-MRI Electromyogram Amplifier amplifies general and skeletal muscle electrical activity. The amplifier functions directly with AcqKnowledge to automatically integrate the raw EMG signal and provide a detailed frequency analysis of the EMG data. As it incorporates fast response and settling time characteristics, it can also be used to monitor single-fiber EMG, motor unit, and peripheral nerve action potentials.

The EMG100C-MRI amplifier should be used with the MECMRI-BIOP MRI cable/filter set.

For fEMG, EL510 disposable, prewired, Ag-AgCl , RT electrodes are recommended; they are gentle on the skin, conform well, and can be cut down to reduce the contact area (ADD204 can also be used to reduce the contact area).

The EMG100C-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: EMG100C-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.

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

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

In every aspect, data recording is easier and the final results are cleaner when using the MRI smart amplifiers to record physiological data in the fMRI or MRI.

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.
