Item Description
Computer electroencephalograph system for EEG and EP recording and analysis with digital video monitoring feature.

EEG Recording

Computer electroencephalograph system for EEG and EP recording and analysis with digital video monitoring feature.

Computer electroencephalograph BRAINTEST allows to record EEG over 4-21 channels in system “10-20” with one ECG lead synchronously by two ways: recording on the investigation protocol or continues monitoring type recording.

The system provides high-quality EEG recording in any not shielded room due to excellent technical characteristics of the device and special built-in software.

BRAINTEST system automatically performs control of electrodes setting quality both while putting them on and during all recording session in the way of impedance measuring. Results of the control are indicating on the front panel of the device and computer monitor.

Set of different filters performs real-time digital filtration.
User can change amplitude and time scaling for convenient form of visualized electroencephalogram while recording and reviewing.
Electroencephalogram can be screened in any customized montage (mono-, bipolar, and combined systems of leads). To differ the view of EEG user also can build various arbitrary systems of leads and then use them in the program.
Our EEG system provides audio and visual stimulation. User can set duration and frequency modes in the program by special setting mode.

For patient’s behavioral responses examination at the same time with EEG recording patient’s video recording to hard disk of PC is possible.
Modern video camera with swivel control panel and remote control allows a doctor to watch a patient without particular effort and to record picture of those face or body parts and in such angle or magnification, as it is necessary for particular examination. Real time video compression gives opportunity of long term EEG-monitoring.

Processing and analysis of the EEG

EEG system software provides a big set of EEG processing and analyzing methods and resume forms.

EEG reviewing - view EEG in different systems of leads, separating one of the rhythms from the EEG, EEG editing, EEG filtering, two EEGs comparison.

Mapping of various data: power of frequency bands, median frequency of the band, canonograms (ratio between bands), power on all analyzable frequencies, EEG amplitudes, correlation coefficients, coherence coefficients. 2D and 3D - mapping.

Maps over frequency bands allow investigating asymmetry in every standard frequency band (delta, theta, alpha, beta). Every EEG fragment could be mapped; user can choose section for analysis or get integral characteristic in a time of a functional test.

Canonograms – distribution mapping of any ranges ratio pairs.

For better understanding of brain activity process (as brain electrical activity) a complex function of coherence method is using in the system as well as traditional correlation analysis. It allows to calculate and plot auto- and cross-correlograms, correlation coefficients table and map of correlation coefficients distribution.

Consequently, correlation and coherence analysis modes are to investigate condition of brain electrical activity space-time organization.

Spectral analysis – wide settings, using of all standard and additional frequency ranges.
Arbitrary sets of these ranges allow you to realize analysis of any part of EEG quickly and accurately.

Results of spectral (based on Fourier- or wavelet-transform), auto- and cross correlation analysis, coherent analysis, bispectral analysis are represented in tables and figures as well as in graphs, diagrams and distribution charts in the BRAINTEST system.

Probabilistic tomograph: plotting any slice in orthogonal coordinates; superposition of tomograph slices and MRI slices; 3D image of brain electrical activity source.
Tomogram calculation for any EEG fragment, tomogram plotting over all investigation tests.

Table of powers over four standard frequency bands (or more) for all leads in a montage is represented in Digital Data window.

User can evaluate the ratio between constituents of standard frequency band both numerically and qualitative due to Frequency Plane, Band Pie Chart and Digital Data windows.

Maps over Tests mode shows in one window summary activity maps on every functional test over four or more frequency bands.

Maps over Tests, Wavelet-analysis, Compressed Spectral Array, Bispectral Analysis, Distribution Law of Spectral Power modes are for analysis of EEG spectral parameters, their dynamics and changes during functional tests.

Method of evoked potentials investigation

BRAINTEST system allows to make auditory, visual and cognitive (P300) long latent evoked potentials recording and analysis.
There are a lot of facilities of study evoked potentials in the system, e.g. peak automatically determination, latency, amplitude and square under response evaluation, amplitude and frequency mapping, spectral analysis and different investigations responses comparison, graphs, tables, diagrams etc.

Heart rate variability analysis (HRV)
While HRV analyzing system gives results according to the next methods:
• -time domain analysis (statistic);
• frequency domain analysis;
• heart rhythm wave structure analysis;
• variational pulsometry by Baevsky.
• scatter diagram analysis;
Analysis results of several ECG cases of one or more patients may be allocated in the HRV Analysis window.
This information is available for each considered part of the ECG:
• rhythmogram (either heart rate graph or RR graph);
• R-R interval distribution;
• scatter diagram;
• rhythmogram statistic parameters;
• spectrogram
• frequencies components table.

Data storage
Storing the patient card, recorded EEG, case history, medical resume; archiving data to the removable disk; patient searching and sorting; other service function.
It is possible to transfer investigation data via local net or Internet.

Resume forming and printing
For user comfort work there are several ways of forming text resume in the system. User may use one of templates, “question-answer” mode, and arbitrary text form.
Automatic EEG description gives the user common information about EEG spectral distribution.
“Question-answer” mode allows to make quickly and easy text resume of any complexity level and any size using templates.
All EEG views, graphs, diagrams etc., all analysis results could be printed. Page makeup is absolutely arbitrary. For better and easier report building there is preview mode in the system.
