Radiophysical System for Examining Functional State of a Patient's Brain

摘要

The radiophysical system MRTRSfor functional study of the brain with one multichannel microwave radiother-mograph measuring the intrinsic electromagnetic radiation of brain tissue within a range of frequencies from 650 to 850 MHz is considered. The structure and basic characteristics of the system are described. It is shown that the insertion into this structure of additional measuring channels for detection of the signals defined by autonomous regulation of heart and changes in neurohumoral processes in the cardiovascular system raises information value of the study. A new software system of secondary signal processing was developed. This software is applied to spectral analysis by means of modified basic Morlet wavelets, which detects time and frequency heterogeneity of studied processes.
