I-Colour Doppler ultrasound ngokuvamile isebenzisa ubuchwepheshe bokuzihlanganisa ukuze kucutshungulwe isignali ye-Doppler. Isignali yokugeleza kwegazi etholwe ubuchwepheshe be-autocorrelation inombala futhi ibekwe phezulu esithombeni esinezinhlangothi ezimbili ngesikhathi sangempela ukuze sakhe umbala wesithombe sokugeleza kwegazi se-Doppler ultrasound. Ngokuvamile kuhlanganisa ama-probe (amalungu afanayo anezigaba, amalungu afanayo anezigaba, amalungu afanayo ayi-convex, i-mechanical fan scan, i-4D probe, i-endoscopic probe, njll.), i-ultrasonic transmitter/receiver circuit, ukucubungula isignali nokuboniswa kwesithombe. Ukusebenzisa ubuchwepheshe be-Doppler ye-ultrasound kanye nesimiso se-ultrasound echo, yethu Umshini we-Doppler ultrasound wombala kanyekanye uqoqa ukunyakaza kokugeleza kwegazi, ulwazi lokunyakaza kwezicubu kanye nesithombe sezicubu zesitho somuntu.
