Abstract
The method for automatic calculation of the envelope of the blood flow velocity curve in spectral Doppler imaging has been implemented in the prototype 128-channel ultramobile ultrasound B-mode scanner under the research project POIR.01.01.01-00-1462/19. Based on the determined envelopes, algorithms were developed for automatic determination of the most important characteristic points of the Doppler blood flow waveform in the Pulsed Wave Doppler imaging mode and the most relevant blood flow parameters. Sufficiently good repeatability and precision with low computational complexity were obtained.
