Artifact Reduction
Detect and reduce artifact with the touch of a button
Persyst Artifact Reduction (AR) works in near-real-time to reduce EMG, Electrode Artifact and Eye Movement. Using Blind Source Separation, Persyst AR selectively reduces these artifacts without attenuating or otherwise altering the underlying Cerebral signal. This results in an artifact-reduced EEG with 40x less cerebral signal distortion than a standard 15Hz high-cut filter.
When reviewing EEG, one of the big issues is the presence of artifacts. The signal from EMG and Eye Movements can often be much larger than the cerebral signal. Additionally, in real-life recordings, electrodes frequently come loose or experience other issues further obscuring or confounding the signal. Persyst AR recognizes artifct from loose electrodes and excludes the relevant channels to allow the reader to clearly see the remaining channels.
Persyst Artifact Reduction reduces artifact in the EEG at the touch of a button without the use of distorting filters. The original EEG is always shown in the background, so the reviewer can see what portions of the signal have been removed. The artifact reduced signal provides a better recording, so the Trending and Spike and Seizure detection algorithms produce more clinically relevant information.
Artifact Reduction is even more
