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.
