This article describes possibilities of multifractal analysis application to evaluate the short-term signals of brain microwave radiation recorded by the Radiophysical complex MRTHR for a group of psychologically healthy patients. Limitations of the multifractal fluctuation analysis method for evaluation of the fluctuation processes of brain regulation are considered. For this purpose, time series of two channels of microwave radiation of the parietal areas of human brain were processed. The results define the limits of applicability of the multifractal detrended fluctuation analysis (MFDFA) method by the time window from 10 to 70 s and correspond to the two independent areas of periods of fluctuations of brain microwave radiation with different physiological nature that were justified by other methods. The obtained estimations prove the multifractal nature of the brain microwave radiation signals. These findings suggest that diagnostic possibilities of the modernized Radiophysical complex MRTHR can be increased with the usage of the multifractal analysis to functional studies of the microwave radiation signals of the brain.
