Persyst introduces the fifth-generation EEG Suite:

The most advanced detection, monitoring and analysis software is also the easiest to use with dramatic advancements in Persyst display technologies and a highly-streamlined user interface.

Future-proof your continuous EEG monitoring in the EMU, ICU, neonatal and more.

Reveal™ Rosetta: Reached a milestone by achieving the highest seizure detection sensitivity and the lowest false-positive rate—creating the first seizure detector that performs at near-expert performance in real-world conditions. And, not just with perfectly clean recordings and classic temporal seizures, but across the widest range of recording environments, clinical applications and seizure morphologies. In other words, Reveal™ Rosetta is designed to perform when and where you need it most. It has been designed for both the Epilepsy Monitoring Unit and the Intensive Care Unit, for patients as young as one month of age. This provides you with seizure detection that provides consistency, simplicity and power for your clinical team.

MagicMarker Bedside: Developed in consultation with neurologists, technicians and non-EEG clinical staff to be user-friendly for your entire clinical team for monitoring and review. By integrating Reveal™ Rosetta with the Comprehensive EEG Monitoring trend panel, you have a consistent, easy-to-use platform for checking your Epilepsy Monitoring Unit and Intensive Care Unit patients.

MagicMarker Advanced: Fully integrated with Insight II EEG Review, and provides a suite of advanced review, analysis and research tools for the advanced EEG'er.

ClearTrend: Adaptive Artifact Rejection uses sophisticated neural-network algorithms to detect most artifact. Any bad channel that will affect the MagicMarker trend is dynamically removed to preserve the accuracy of the trend display. This means more accurate trends that are easier to interpret, and notification thresholds that are easier to set.

ElectroDx: Using ClearTrend technology to recognize artifact, ElectroDx detects bad channels on-the-fly and alerts clinicians with a simple, easy-to-read display—regardless of the cause of artifact.

Rhythmic Run Detection and Display (R²D²): Bridges the gap between seizure detection and review with a technology called "seizureprints." Like fingerprints and voiceprints, a seizureprint provides a graphical representation of a seizure's evolution, so that the clinician can visualize the morphology, spatial distribution and frequency of seizure activity at a glance. Seizure review is improved with a bird's-eye view never before possible.

Because R²D²is highly resistant to artifact, and because it is easy to read, the information provided by seizureprints is greatly improved over current text-based seizure indications.

Comprehensive EEG Monitoring with Single-Panel Trending: No more searching for the appropriate trend panel for different clinical applications. Rhythmic Run Detection and Display (R²D²), EEG Asymmetry Indices, Suppression Ratios and aEEG provide a single effective trend panel for most clinical applications.

Regional and Hemispheric Asymmetry Indices: Rather than relying on a-priori knowledge of where frequency changes associated with ischemic changes or seizures will occur, the EEG Asymmetry Index (EASI) looks for asymmetries between homologous electrodes in any frequency band. Combined with Adaptive Artifact Rejection (AAR), EASI provides a simple, powerful and flexible indication of any regional or hemispheric change in EEG activity—with unparalleled accuracy.

Regional and Hemispheric Asymmetry Spectrograms: Taking EASI technology another step, Relative EEG Asymmetry (REASI) Spectrograms provide a simple indication of the frequency and region/hemisphere of EEG asymmetry. Combined with Adaptive Artifact Rejection (AAR), REASI Spectrograms provide unparalleled sensitivity and accuracy.

MagicMarker Email: When thresholds are exceeded, MagicMarker can email you with the notification, including images of the trend and EEG waveforms at the time the thresholds were exceeded. Plain-language seizure notifications and EEG asymmetry trends make threshold setting simple and powerful, while ClearTrend Adaptive Artifact Rejection minimizes false-positive notifications.

 

 

Persyst EEG Suite Version 2008.10.22:

The final release of the fourth-generation Persyst EEG Suite brings multiple refinements and updates to EEG file format support.

• If you have adopted the "new" 10-20 convention, but still have recordings that use the "old" convention, this enhancement will be very helpful for you. There is now automatic support for both the 10-20 conventional channel labels T3, T4, T5, T6 and the newer convention of T7, T8, P7, P8 (respectively) across EEG Suite analysis tools. The EEG Suite automatically adjusts as the new convention is detected in your recordings.
• Persyst's breakthrough Adaptive Artifact Rejection has been enhanced for improved performance on very low amplitude recordings.
• Trends equipped with R²D² have been tuned to provide faster off-line scanning performance.
• The loading of very long recordings (e.g., >48 hours) is faster.
• Updated EEG file format support is available for Xltek NeuroWorks, Nihon Kohden 1100/2100, Cadwell Easy III and OSG Brain RT.

2009 will usher in the release of the fifth-generation EEG Suite with dramatic advancements in EEG monitoring and analysis technology.

Updated Adaptive Artifact Rejection for improved performance on very low amplitude recordings.
