Performance and Usability

Flexibility to Process Signals as Needed

Pegasus receives the acquired signals from the ATLAS Acquisition Amplifier as raw, wide bandwidth, high resolution, high-rate sampled data records. Only the selected reference source has been subtracted from the signal input. Pegasus configuration and processing allows each input to be digitally “cloned” and processed as multiple sources: for example, as high frequency Single Unit Action Potentials and as EEG, even in distinct frequency bands (low frequency EEG, and High Frequency Oscillations), each with different filters, input signal ranges and file storage rates. This allows clinical review data to be stored at “normal EEG rates,” and microwire and research electrode signals to be stored at the full sampling rate.

Referencing at the Analog Signal Stage

Pegasus maintains and controls the flexible referencing capabilities of the ATLAS Acquisition Amplifier. This consists of
8 local references per 32 channel bank and 7 global references shared among banks. Referencing occurs before the signals are digitized to provide the best artifact rejection. In Pegasus, dedicated reference inputs or normal input channels may be used as references for any channel. Pegasus maintains references and channels by the name assigned in the configuration set-up to avoid errors and confusion.

Patient-Centered Data Storage

Since invasive epilepsy recording involves days, often weeks, of data recording, Pegasus stores user selectable patient information, electrode configuration and set-up, and data storage file locations from all sessions in a single location. Data files are given unique identifiers (also copied in the file headers) for verification back to the original data recording session for the patient. Recordings are segmented into time-based “sessions” where data files are automatically closed as new session data files are opened. Protected Health Information (PHI) can be encrypted for HIPAA compatibility.

HD Video Support

Pegasus supports HD video streams from an IP Ethernet camera. All video frames are time-stamped and added to the Patient database files. The use of IP cameras allows streaming video to be displayed to multiple locations on the local network, such as to remote monitoring and nurse stations.

Pegasus Software replaces ATLAS Software for clinical research.
