Hoʻohana maʻamau ʻo Color Doppler ultrasound i ka ʻenehana autocorrelation no ka hana hōʻailona Doppler.ʻO ka hōʻailona kahe koko i loaʻa e ka ʻenehana autocorrelation ua hoʻopaʻa ʻia a hoʻopaʻa ʻia ma luna o kahi kiʻi ʻelua-dimensional i ka manawa maoli e hana i kahi kiʻi. kala Doppler ultrasound kiʻi kahe koko.ʻO ka mea maʻamau, aia nā probes (phased array, linear array, convex array, mechanical fan scan, 4D probe, endoscopic probe, etc.), ultrasonic transmitter/receiver circuit, hōʻailona hana a me ka hōʻike kiʻi.Ke hoʻohana nei i ka ʻenehana ultrasound Doppler a me ke kumu o ka ultrasound echo, kā mākou ʻOhi ka mīkini kala Doppler ultrasound i ka manawa like i ka neʻe ʻana o ke koko, ka ʻike o ka neʻe ʻana o ka ʻiʻo a me ke kiʻi kiʻi ʻana o ke kino kanaka.
