- Less sensitivity to electrode and transducer lead placement
- Improved gain selectability
- No missing spectra in physiological signal frequency band
- Minimizes computer-based real-time or post-processing signal processing
- 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.
