Determining the envelope of the blood flow velocity in Doppler ultrasound

Majewski Jarosław, Opieliński Krzysztof J., Żogał Paweł, Wiktorowicz Andrzej

International Journal of Electronics and Telecommunications

2025

Vol. 71, No. 4

This paper describes and tests a method for automatically determining the envelope of the blood flow velocity curve in ultrasonic Doppler imaging, which was implemented in a prototype of the 128-channel mobile ultrasound B-mode scanner. On the basis of the determined envelopes, algorithms were also developed for the automatic determination of the most important characteristic points of the Doppler blood flow spectrum in pulse wave Doppler imaging mode and the most relevant blood flow parameters. Sufficiently good repeatability and precision were obtained with low computational complexity.
