Persyst Trending

Persyst 15 offers a large number of Trends, and they are all configurable to your use case and preferences. Our unique vsBaseline Trends allow you to see changes that might be occurring over the space of hours or days. New in Persyst 15 is the ability to quickly create montages and Trends for Intracranial records. This can dramatically speed up review time and help identify seizure onset channels.

Persyst Neuroimaging Tools

Persyst 15 adds functionality to incorporate neuroimaging into EEG review.

  • Persyst EEG Electrical Source Imaging (ESI) now has a new MRI viewer for ESI results. Dynamically change the threshold of ESI results, overlay and compare results across clusters and time points, and export to DICOM.
  • The Persyst iEEG Viewer automatically co-registers pre- and post-implant CT or MR images. The 3D positions of implanted electrodes can be quickly calculated and visualized with minimal user intervention. Customized functional electrode groups and their positions can be exported to DICOM for ongoing surgical planning.

New! iEEG Electrode Localization.

Persyst Detections

Persyst 15 continues to offer the most advanced spike and seizure detection available with accuracy up to ten times better than previous versions. New in Persyst 15 is a neonatal-specific seizure detector. The Neonatal Seizure Detector is the latest cutting-edge technology from Persyst that leverages deep learning and AI. The detector operates on reduced electrode arrays from double-distance down to just three electrodes. Combined with an optimized trend panel, Persyst 15 can assist in the monitoring and analysis of neonatal recordings.

New! Neonatal Seizure Detector.

Spike Review

The Persyst Spike Review tool for clustering spikes according to the electrode of maximal amplitude has been significantly enhanced in Persyst 15. Opening a spike cluster now displays an average propagation map of selected members of the cluster along with the overlaid waveforms of the selected members for assessing spike morphology. Additionally, selecting any other spike in the cluster displays that spike’s propagation map and waveforms for comparison to the selected set. Spike Review has also been optimized for selecting spikes for localization with our new EEG Source Imaging capabilities.
