120. Necessity to improve the efficiency of measurements of blood-flow indices in Doppler technique is shown. The opportunity is based on an idea to measure current average power of ultrasonic signal instead of waveform analyze which is in use commonly. Moreover an opportunity of ultrasonic signal processing based on discrete wavelets transforms is considered. It is shown that discrete wavelet transform can detect the overall periodicity of an noise-type envelope of Doppler blood flow signal.
