Launi Doppler kwarara Hoto

Launi Doppler kwarara Hoto tsarin iya lokaci guda nuna nau'in siffar B-type da Doppler data kwarara jini (jini kwararar shugabanci, kwarara gudun, kwarara watsawa) na dual duban dan tayi scanning tsarin. Ƙarfin launi na angio (CPA) ya gano ƙarfin baya na ƙwayoyin jini a cikin jini, wanda bai bambanta jagorancin gudana ba, kuma ba shi da dangantaka da kusurwar θ (kusurwar tsakanin jagorancin motsin sauti da kuma jagorancin jini. ). CPA na iya inganta ƙwarewar ganowar jini, musamman dacewa don nuna ƙananan jini na ƙananan jini, amma ba zai iya nuna jagorancin jini ba.

Harmonic Hoto

Harmonic Hoto yana amfani da yaduwa mara daidaituwa na duban dan tayi ta kyallen jikin jiki. Lokacin da mitar motsin sautin da aka fitar ya kasance f 0, mitar amsawa (saboda tunani ko watsawa) ya haɗa da f 0 (wanda ake kira da mahimmancin kalaman), 2f 0, 3F 0 da sauransu Na biyu masu jituwa (2f 0) yana da mafi girman kuzari. .

Ultrasonic Harmonic Hoto (UHI) ya dogara ne akan bayanan jikin ɗan adam wanda ke ɗauke da jituwa ta biyu a cikin amsawa (tunani ko watsawa). Hoto mai jituwa ba tare da UCA ana kiransa hoton jituwa na asali ko hoton jituwa na nama ba. Hoto masu jituwa ta amfani da UCA (wakilin bambanci na Ultrasound) ana kiransa hoton bambancin jituwa
