Color Doppler inoyerera imaging

Rudzi rweDoppler kuyerera kwekufungidzira system inogona panguva imwe chete kuratidza B-mhando yemufananidzo uye Doppler ropa rekuyerera data (kuyerera kweropa mafambiro, kuyerera kwevelocity, kuyerera kupararira) yehuviri ultrasound scanning system. Rudzi rwesimba angio(CPA) yakaona simba rekudzokera kumashure remasero eropa mukuyerera kweropa, iro risingasiyanise mafambiro ekuyerera, uye rakanga risinei nechekuita nekona θ (iyo kona iri pakati pekunanga kwemasaisai eruzha uye mafambiro ekuyerera kweropa. ) CPA inogona kuvandudza kunzwisiswa kwekuona kuyerera kweropa, kunyanya yakakodzera kuratidza kuderera-kumhanya kweropa kuyerera kwemidziyo midiki, asi haigone kuratidza gwara rekuyerera kweropa.

Harmonic imaging

Harmonic imaging inoshandisa isiri-mutsara kupararira kwe ultrasound kuburikidza nemuviri tishu. Kana kuwanda kwekubuda kweizwi wave f 0, kuwanda kwe echo (nekuda kwekuratidzira kana kuparadzira) kunosanganisira f 0 (inonzi fundamental wave), 2f 0, 3F 0 zvichingodaro Yechipiri harmonic (2f 0) ine simba guru .

Ultrasonic harmonic imaging (UHI) inobva pamashoko emuviri wemunhu anotakurwa nechipiri harmonic mu echo (reflection kana kuparadzira). Harmonic imaging isina UCA inonzi native harmonic imaging kana tissue harmonic imaging. Harmonic imaging uchishandisa UCA (ultrasound musiyano mumiririri) inonzi musiyano harmonic imaging
