Tae Doppler ultrasound tikanga whakamahi hangarau autocorrelation mo Doppler tukatuka tohu. Ko te tohu rere toto e whiwhi ana i te hangarau autocorrelation he tohu-tae, ka whakakikoruatia ki runga i te ahua ahua-rua i roto i te waa tuturu hei hanga he tae Doppler ultrasound whakaahua rere toto. Ko te nuinga o nga wa kei roto ko nga rangahau (te raupapa raupapa, te raupapa raina, te raupapa convex, te tirotiro miihini miihini, te tirotiro 4D, te rangahau endoscopic, me etahi atu), te hikohiko tuku / kaiwhiwhi ultrasonic, te tukatuka tohu me te whakaaturanga whakaahua. Te whakamahi i te hangarau ultrasound Doppler me te kaupapa o te echo ultrasound, to tatou Ko te miihini ultrasound Tae Doppler ka kohia i te wa kotahi te rere o te toto, nga korero nekehanga kiko me te whakaahua kiko o te tangata.
