On Stationarity of Transcranial Blood Flow Velocity Registered with Doppler Sonography Methods

A. A. Ivankov, A. D. Samarin
Price: 50 руб.
Measurements of transcranial blood flow retrieved with Doppler sonography methods in real-time mode were investigated. Consistent and inconsistent estimates of power spectral density in infra-low range were analyzed. Hypotheses on the stationarity of such processes were tested.
Keywords: transcranial blood fl ow, Doppler sonography, Fourier spectra, PSD, power spectral density consistent estimate, Welch method.
