EEG BRAINTEST

Computer electroencephalograph BRAINTEST allows recording of 1 to 21 EEG channels in the system "10 - 20" in synchronism with the electrocardiogram on one lead, and two channels EOG according study protocol or in monitor mode.

High technical characteristics of the device and special software implemented in the system produces high quality recording of the electroencephalogram in any room.
Quality control electrode application automatically during the installation and during the whole period of EEG by measuring the interelectrode impedance and corresponding display on the front panel of the EEG amplifier.

 

various filters system performs digital filtering EEG in real time.

To visualize the electroencephalogram usual form for the physician can change the amplitude and time base of the EEG during recording and playback.

 

EEG is displayed on the screen in any selected installation by the user (monopolar, bipolar, mixed). To change the representation of the EEG system allows you to create arbitrary montages and later use them in the program.

The system provides the possibility of light and sound stimulation; duration and frequency of stimuli are software with a special configuration of the system.

The implemented system quality digital EEG - video monitoring allows simultaneous EEG recording of a patient record video on your PC hard drive.
Modern video camera with remote control allows the physician to monitor stress - free for the patient and record an image of those parts of the body or face, and in this perspective, and increase as needed for a particular examination. Compression of video in real time provides the opportunity for a long EEG video monitoring (48 hours).

 

 

Processing and analysis of EEG
The system software provides a wide range of EEG processing and presentation of the results of its analysis.

 

Viewing the EEG - viewing in a variety of systems lead, podiapazonnaya filtering, editing EEG, EEG filtering, comparison of the two electroencephalograms.

Mapping the various data: power frequency ranges, median frequency spectrum kanonogramm (ranges of ratios), the power at all frequencies of the analyzed EEG amplitude, correlation coefficients, coefficients of coherence; two and three dimensional mapping.

To study the state of the space - time organization of the brain electrical activity in the system of the method of the complex coherence function and the traditional correlation analysis, which allows you to calculate and construct a road and crosscorrelograms, table of correlation coefficients and their distribution cartogram.
Maps of frequency bands make it possible to study the asymmetry in each of the standard ranges (delta, theta, alpha, beta). In this mapping may be subjected to any visible EEG fragment analyzed to allocate land or receive integral characteristic for the period of one of the functional tests.

 

Graphs, charts and tables

In BRAINTEST electroencephalograph computer implemented representation of the results of spectral analysis (based on a Fourier transform or Wavelet - flexible configuration system), automobile and krosskor relational, coherent, bispectral analysis in the form of tables and numbers directly or in the form of graphs, charts and distribution maps, with zoom and print. The presentation of the results can be customized according to user preferences.

 

Probability Tomography: the construction of any of sections in an orthogonal XYZ coordinate system aligned with the anatomical structures, three - dimensional representation of the electrical activity of the hearth.
Calculation of tomograms for any portion of the EEG, the construction of tomograms of all samples studies

 

 

Window Digital data is a table of capacities in all standard ranges for all installation leads.
Frequency window plane circular band diagrams and digital data make it possible to evaluate the ratio of components standard ranges both quantitatively and qualitatively.

 

for each of the sample study in four frequency bands Maps Mode Sample prints in a single window cards total activity.

To assess the dynamics of EEG spectral characteristics and their change in the course of functional tests designed to map mode Sample, Wavelet analysis, Compressed spectral regions, Bispectral analysis of the law of distribution.

Three - dimensional mapping
To facilitate the visual perception of the cards in their three - dimensional system provides an option, which is a three - dimensional model of the head, which in accordance with the electrodes and corresponding values for the signal, is superimposed a certain color surface.
To localize the focus of electrical activity in the three - dimensional model in the form of rings is shown cutting plane.

 

Summarized information on the spectral composition of the EEG is represented in the automatic description of the electroencephalogram.

Recording and analysis of evoked potentials (EP)

 

The system allows the recording and analysis of auditory, visual and cognitive (Conditional expectations and negative wave phenomenon P300) long - latency evoked potentials.

The system provides the following features for the study of evoked potentials:
- automatic determination of the peaks;
- Calculation of latencies, amplitudes and areas under the response;
- amplitude and frequency mapping;
- spectral analysis and comparison of the responses of the different studies,
- presentation of the results of analysis in the form of graphs, tables and charts.
For a more in depth study of the functions of the visual system of the patient using visual registration VP at reversing checkerboard pattern.
Analysis of heart rate variability (HRV)
In the analysis of heart rate variability of the system provides:
- the statistical analysis;
- analysis of wave structure of heart rate;
- analysis of scattergrams;
- Variation of pulsometry Baevsky.
The analysis window may be located HRV analysis of multiple ECG fragments same or different patients.
For each considered section ritmokardiogramma output (or the heart rate graph or graph RR), a histogram distribution of RR intervals scattergram, statistical parameters rhythmogram, spectrogram graph, the numerical parameters spectrogram

 

Data storage

Saving patient information recorded EEG, medical history and findings, archiving records to removable media, sort and search for patients, other service functions.

The ability to transfer research data on the local network or the Internet.
The possibility of formation of statistical data for the selected period.
Forming opinions and printing

 

To facilitate the issuance of the conclusion of the doctor offered several possibilities of forming part of the conclusion text (automatic description of the EEG, one of the templates for a question and answer system, in free text form).

"Question - answer" mode allows for one of the existing and changing patterns in the dialogue form to quickly build a text conclusion of any size and complexity.

All forms of representation of the EEG, the results of its analysis and conclusion, can be printed. Layout sheet completely arbitrary. To facilitate the preparation of the reporting form, the system provides a preview mode.

The cost of the system include:
Delivery, installation and commissioning
specialist training
Warranty for two years
After - sales service and expert advice for the duration of the system operation
