PRECISE FREQUENCY-PATTERN ANALYSIS TO DECOMPOSE COMPLEX SYSTEMS INTO FUNCTIONALLY INVARIANT ENTITIES

摘要

Methods, systems, apparatuses, including computer programs encoded on computer readable media, for registering a multichannel time series from data collected from a plurality of channels monitoring a body. Each channel corresponds to one or more sensors. The data from all channels is precise Fourier transformed to frequency data in a frequency domain. The frequency data is inverse Fourier transformed for each frequency in the frequency domain. Elementary coherent oscillations are determined from the inverse Fourier transformed frequency data. Partial spectra of the functional entities include frequencies with similar patterns from the elementary coherent oscillations. A functional tomogram of the body is calculated from the distribution in space of the energy and/or dominant directions of the sources, producing the partial spectra. The partial spectra is inverse Fourier transformed to reconstruct a time series for the functional entities.
