Purpose

24-channel Compact Neuro encephalograph can be used to record and analyze EEG using 21 channels, as well as three universal polygraph channels (ECG, EMG, and EOG). The main purpose of the system os to diagnose epileptical changes in EEG, monitor EEG at night, as well as the dynamic evaluation of the functional activity of the brain. The monitoring can be carried out in both monopolar and bipolar modes with simultaneous recording of the patient's state using a web-camera.

When the device is used for routine examinations it's highly recommended to use silicone headsets. In case of continuous use the device shall be used with a fabric headset with a set of electrodes.

The device supports the following features during the real-time usage:

  • changing scales of time, amplitude, and filter parameters
  • custom range filters allowing selecting specific frequency ranges
  • checking the quality of electrodes positioning (impedance measuring)
  • filtering power line disturbances
  • choosing bipolar schemes
  • recording with/without the protocol, custom order of samples
  • notepad with timestamps and events
  • video monitoring using several cameras

The device supports the following features during the real-time usage and after the registration:

  • spectral analysis
  • the cartographical analysis in 2D and 3D
  • correlation analysis
  • automatic artifact detection

The device supports the following features after the registration of EEG:

  • restoring lost fragments of EEG from SD card
  • automatic searching of ranges with pathologic activity
  • automatic report generation in text or in table formats
  • recording results and video to CD
  • import/export of examination results
  • EEG signals export in EDF and CSV
  • remote impression writing using the cloud storage or a network folder

Software features

  1. The convenient database allows fast patient information adding.
  2. Supports parallel recording from two or more cameras.
  3. EEG registration can be carried out with available of with custom protocols.
  4. Quality of the electrode attachment control by measuring the impedance between the electrodes in real-time.
  5. Both reports and examination information can be stored and transferred using the cloud storage.
  6. Automated impression creation for functional batches in the report.
  7. Ability to use digital filters as in real time, as well as after the signal registration.
  8. Results of the examination can be exported in CSV, EDF, and EDF+formats, and processed using the most popular international software: LORETA, EEGLAB, BESA, CURRY etc. 
  9. Supports restoration of the EEG data from a flash card in case if the patient went out of the receiver coverage.

Main types of EEG processing:

  • automatic mode for artifacts identification
  • automatic searching of ranges with pathological activity, including continuous records
  • spectral and correlation analysis
  • the cartographical analysis in 2D and 3D
  • calculation of the hemispheric asymmetry​, index, and the rhythm frequency
