Compact-Neuro (21 channels)

The system is an extended version of a standard encephalograph with an increased number of leads, which allows for in-depth EEG examination in neurological and psychiatric diagnostics, as well as in epileptology. The system can be used for mass screening EEG studies: checkup, medical examinations of drivers, operators, professional examinations, professional suitability assessments, etc.

Description

Compact-Neuro (21 channels) is designed to conduct routine (according to generally accepted methods) and in-depth examinations of the bioelectrical activity of the brain both according to randomly selected (built-in) standard examination protocols, and according to protocols created by the user independently (taking into account the flexible setting of the necessary protocol parameters). Recording is performed using any number (up to 21) of standard electroencephalographic leads in monopolar or bipolar mode with the possibility of parallel recording of the patient's video image using a webcam.

System and software capabilities

The main types of mathematical analysis and EEG processing:

automated search for areas of pathological epileptic activity, including for long-term recordings;
automatic search and selection of artifacts in the EEG signal;
spectral analysis;
correlation analysis;
real-time topographic 2D and 3D mapping;
calculation of hemispheric asymmetry, index and frequency of rhythms.

Key software functions:

quality control of electrode placement according to interelectrode resistance in real time (impedance measurement function);
automatic description of functional tests in reports, automated generation of reports in text and tabular form;
the presence of a database of pre-installed electrode placement schemes (monopolar and bipolar) and the ability to create your own (customized) schemes using the built-in electrode placement scheme editor;
the ability to print out necessary sections of the EEG signal in accordance with the set parameters (printing time interval, printing the challenge tests, printing the active screen with a signal and the entire registered EEG signal);
EEG recording according to pre-formed (pre-installed) protocols and the ability to create user protocols with the required number and parameters of challenge tests, including for phonostimulation and photostimulation (stimuli frequency, power, pulse, duration of conduction, pauses, etc.);
EEG signal recording according to a protocol and without a protocol, the ability to change the sequence of challenge tests as part of the protocol;

the ability to add events, EPI activity zones, artifacts, text notes, and tests to the recorded signal both in the EEG signal recording mode and after its completion;
the opportunity to simultaneously record video images during the examination;
the ability to select (and switch) bipolar circuits both during the examination (in real time) and upon its completion;
use of digital filters both in real time and after completion of signal recording, filtration of network interferences;
the presence of bandpass filters to identify frequency ranges;
switching signal display scales – by time (sweep) and amplitude (sensitivity), filter parameters both in real time and after recording the EEG signal;
built-in database of standard templates and phrases for filling in the fields of the reporting form (pre-installed templates for drawing up conclusions), the ability to add, save, edit and delete user templates and phrases.

Database functionality:

the user-friendly and intuitive database interface allows to quickly fill in information about the patients during their registration in the electronic card file;
mechanisms for sorting the patient list by criteria (alphabetical order, gender, age, registration date and last examination date) and quick search for a patient from the list by several letters of the full name;
wide possibilities for distant and remote interpretation of examinations via cloud storage or a network drive: conducted examinations are automatically uploaded to any convenient cloud service, which provides the ability to access examinations from anywhere in the world;
the ability to export the reporting form to Microsoft Office Word and PDF;
export to Loreta program;
the opportunity to record a portable version of a patient's examination on a disk and/or flash card, for viewing which (on another PC) no specialized software needs to be installed;
import/export of conducted EEG examinations;
EEG examinations can be exported to CSV, EDF, EDF+ formats and processed using well-known international programs such as LORETA, EEGLAB, BESA, CURRY, etc.;
high level of security for stored data – encryption of examination results, backup and restoration of the database from a backup copy;
the ability to create databases individually for each user (specialist).
