SyncBox Scanner Interface Duo
  • Synchronizes the clock of BrainAmp MR amplifiers with the master clock driving the MRI scanner’s gradient system

  • Significantly reduces timing related errors and boosts the quality of gradient artifact correction

  • SyncBox scanner interface and scanner clock output are physically connected (using galvanic coupling) to avoid potential influence on the MR scanner system

  • Seamless integration with BrainVision Recorder and Analyzer software by means of dedicated trigger codes and implemented algorithms

SyncBox: Must-have solution to boost data quality for concurrent EEG and fMRI recordings

Phase synchronization between the EEG equipment and the MRI scanner results in temporal stability of the EEG acquisition in relation to the switching of the gradients during the MR acquisition. This leads to significant improvement in the quality of gradient artifact correction and therefore the recorded data quality.

The SyncBox is essential to recording high quality EEG data in the MR environment and is it compatible with all major commercial MRI scanners available on the market.
