NEW! MRI Smart Amplifiers!
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. There is no longer any requirement to over-sample the amplifier output to capture every nuance of MRI artifact to train secondary computer-based processing steps to remove such artifact.
Features:
1) Less sensitivity to electrode and transducer lead placement
2) Improved gain selectability
3) No missing spectra in physiological signal frequency band
4) No requirement for acquisition oversampling
5) Minimizes computer-based real-time or post-processing signal processing
6) Cleaner data available as real-time analog output
MRI version amplifiers are compatible with MRI cable/filter sets.
IMPORTANT! See Safety Guidelines for recording biopotential measurements in the MRI environment.
The EMG100C-MRI Electromyogram Amplifier amplifies general and skeletal muscle electrical activity. The amplifier functions directly with AcqKnowledge to perform real-time EMG integration.
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.
Use the AcqKnowledge software to automatically integrate the raw EMG signal and provide a detailed frequency analysis of the EMG data.
