Sienna Electroencephalograph

Advanced Digital EEG System for Clinical Neurodiagnostics

Sienna Electroencephalograph is a comprehensive, modular digital EEG system designed for routine clinical studies and a broad range of electroencephalography applications.

Available in 40, 80, 120 and 160 channel configurations, Sienna combines EEG acquisition, review, analysis, digital video and remote monitoring capabilities within a flexible platform. Its modular architecture allows healthcare facilities to configure the system according to their clinical and workflow requirements.

Designed for modern neurodiagnostic environments, Sienna provides clinicians with an integrated solution for recording, reviewing, analysing and managing EEG data.

Flexible Multichannel EEG Recording

Configure the EEG System Around Your Clinical Requirements

Sienna is available in multiple channel configurations, from 40 to 160 channels, providing flexibility for different clinical and diagnostic requirements.

The modular architecture allows the system to be configured and upgraded with different hardware and software options.

This makes Sienna suitable for healthcare environments looking for a scalable multichannel EEG system rather than a fixed, single-purpose EEG platform.

Channel configurations include:

• 40-channel EEG
• 80-channel EEG
• 120-channel EEG
• 160-channel EEG

Advanced EEG Acquisition and Review

Sienna provides integrated EEG recording and review software designed to support the clinical workflow from signal acquisition through analysis and reporting.

The acquisition and review screens can be configured independently, while simultaneous split-screen recording and review allows users to monitor ongoing acquisition while reviewing recorded information.

The system also supports event marking and archiving, allowing selected events to be stored and accessed for subsequent review.

Efficient EEG Workflow

Designed to Simplify Clinical Workflows

Sienna incorporates a Workflow Manager designed to integrate routine tasks and improve productivity.

Users can quickly access parameter settings and analysis functions through a user-definable onscreen control-key layout.

The annotation system provides quick access to marked events, while data can also be reviewed according to event or time markers.

This workflow-focused design helps reduce unnecessary steps during EEG recording and review.

Remote EEG Monitoring

Monitor and Review EEG Data Over a Network

Sienna supports remote monitoring, reviewing and archiving over LAN, allowing EEG information to be accessed across a connected clinical environment.

Network connectivity can help support multi-station EEG environments where data needs to be accessed or reviewed from different locations.

This makes Sienna suitable for healthcare facilities seeking a connected digital EEG monitoring system.

High-Definition Digital Video

Combine EEG Data With Video Monitoring

Sienna supports Full HD digital video, providing the ability to combine EEG recording with synchronized visual information.

The system supports multiple camera options, with software-controlled pan, tilt and zoom capabilities available within the Sienna platform.

Video EEG can provide additional context when reviewing clinical events and recorded EEG activity.

Advanced EEG Analysis

Sienna provides a broad selection of software applications for EEG analysis.

• FFT Spectrum Analysis

Frequency-domain analysis can be used to examine EEG activity across different frequency ranges.

• Compressed Spectral Array

Provides a compact visual representation of spectral information over time.

• Compressed Density Array

Supports visual analysis of EEG frequency distribution and changes over time.

• Amplitude Mapping

Provides graphical representation of EEG amplitude distribution.

• Advanced Analysis

Additional analysis programs can be integrated according to the selected configuration.

• BESA Compatibility

Sienna supports BESA compatibility for applicable analysis workflows.

EEG Mapping and Evoked Potentials

Sienna can be configured with optional quantitative EEG, spectral analysis, mapping and evoked potential capabilities.

These options allow the platform to extend beyond basic EEG recording and support more advanced neurophysiological assessment requirements.

ERP functionality is also available as part of the Sienna software ecosystem.

Optional Spike and Seizure Detection

Sienna supports optional automatic spike and seizure detection capabilities.

These features can assist clinicians by highlighting potentially relevant EEG events for further review rather than requiring every section of a long recording to be examined manually.

The detection functions can be particularly relevant in EEG workflows involving prolonged recordings and epilepsy-related investigations.

Complete Polysomnography Capability

The Sienna platform can also support polysomnography (PSG) applications through its available software and hardware options.

This broader capability can help healthcare facilities use the platform across EEG and sleep-related diagnostic workflows.

For facilities that require both EEG and sleep-study capabilities, the Sienna ecosystem provides a flexible approach to system configuration.
