Project summary

The project "Development of methodological and information-technical basis for construction of diagnostic multichannel elect-roencephalographic and electrocardiographic systems with telemetering channel and implementation of the main units of such systems (Short title: DIMEST) is intended for development of new diagnostic methods in electroencephalography and electrocardioghraphy and construction of the miniature components (electrodes, amplifiers, data converters, wireless communication channel with a processing computer, etc.) on the basis of which one can build up diagnostic systems with various functions implementing the developed methods.

These systems with elements placed straightforwardly on the patient body should possess features of stationary systems, while allowing free movements of the patient in the process of examination.

Specialists in the field of medicine and biology will take part in the project implementation. They develop new research methods which, in case of their implementation in practice in the frame-work of DIMEST system, may show the greatest efficiency. These are the method of determination of spatial synchronization of the brain electric potentials (SYNCHRO-EEC) developed by the group headed by Prof. N.E.Sviderskaya and the method of visual representation of electrophysiological characteristics of the heart from noninvasive measurements -(MULTECARTO - Multipolar Eleetrocardiotopography) developed by the group Prof. L.I.Titomir.

On the basis of the SYNCHRO-EEC approach, particular methods and prototypes of devices realizing them will be worked out. These methods and devices will allow to study subtle states of the brain (consciousness, thinking, emotion etc.) As well, diagnostic methods which allow to analyze brain electric activity at various pathologic states (epilepsy, schizophrenia, brain tumors, coma state, etc.) will be created.

On the basis of the MULTECARTO approach, particular methods and prototypes realizing them will be worked out. These methods and prototypes of devices are intended for cardiovascular diagnosis. Also,a method to provide biological feedback for heart activity correction and a device for implementation of this method will be developed.

The execution of this project will result in a base of unified units and software, which may be used to construct multichannel diagnostic systems with various functions. In these systems, the part of equipment intended to pick up and transmit signals from the patient will weigh no more than 0,5 to 0,8 kg and will be comfortably placed on the patient without hindering his movements. This will allow to carry out EEC and ECG investigations under natural conditions (at a working desk, on simulators, at an operator panel, etc.) Such possibilities are especially important for studying consciousness, thinking, emotion, and other states of the brain.

To implement the project, new technological processes (mastering surface mounting, caseless elements usage, and so on) providing miniaturization of the devices, as well as computer software for new diagnostic methods, are to be developed.

At the final stage of implementation of the project the following breadboards of the devices should be constructed:

a) 30-channel electroencephalograph ; realizing the SYNCHROEEG method;

b) 48-channel electrocardiograph realizing the MULTECARTO method.

Along with essential increase in accuracy of evaluation of the organism state, the project promises some commercial profits, insofar as the devices developed on the basis of the project will have rather wide application range (medical diagnosis, professional screenings, professional selection, observation of patients in the course of various types of activity, under extreme condi-tions, and so on).

The multichannel diagnostic devices with a telemetering channel attached to, the patient body, that will be developed as a result of the project proposed, have thus far no analogs.

The project is consistent with the main purposes of ISTC

a) the project implements the results of fundamental research which have been recognized by the world scientific community (see the bibliography in Section 6 and which have not yet been realized because of lack of appropriate technical means;

b) scientists and engineers which have been previously envolved in development of nuclear arms and rocket automatics and are capable of rapidly switching to solve analogous tasks in medical device making, will be engaged in the project;

c) the project will promote the fastest conversion of VNIIA, so as to direct its production facilities in the largest degree to development and production of medical instruments.
