Ngaba i-hald-amhlophe ayithethi ukuba akukho dopler?
Itekhnoloji ye-Ultrasound lilitye lebala lengqolowa yanamhlanje, inika iindlela ezingahlaseli kwaye zisebenza ngokufanelekileyo ukuze zibonakalise izakhiwo zangaphakathi zomzimba. Phakathi kweentlobo ezahlukeneyo ze-ultrasound, emnyama-nemhlophe (okanye emnyama) i-ultrasound kunye ne-doppler i-ultrasound ngamanqanaba amabini eprayimari ohlala ebangela ukudideka. Inye imibuzo eqhelekileyo kukuba i-ultrasound emnyama kunye nemhlophe ichaza ukungabikho kwengqondo ye-doppler. Eli nqaku lijolise ekucaciseni lo mbandela kwaye linike ukuqonda okubanzi lwetekhnoloji yomibini, ukungafani kwabo, kunye nezicelo zabo.
Yintoni i-ulrandaund emnyama kunye nemhlophe?
I-ultraund emnyama-nemhlophe, ekwabizwa ngokuba yi-greyccale ilrasound, yeyona ndlela yesiko neyona isetyenzisiweyo ye-ultrasound. Ivelisa imifanekiso kwizithunzi ezahlukeneyo zegrey, ezimele uxinzelelo lwahlukileyo lwezicubu kunye namalungu.
Isebenza njani i-ultra kunye ne-mhlophe
Inkqubo ibandakanya i-transducer, ekhupha isandi esihamba ngesantya esiphezulu esiya emzimbeni. La mava esandi ayaphelisa amaqela angaphakathi kwaye abuyele kwi-transducer njenge-echobe. I-echoes iguqulwe ibe yimifanekiso ebonakalayo ngumatshini we-ultrasound. Imithunzi eyahlukeneyo ye-grey kwimifanekiso imele imigangatho eyahlukeneyo yoxinano: izakhiwo ezinqabileyo njengethambo elibonakala emhlophe, ngelixa imimandla ehluthayo ifana ne-fleid.
Ukusetyenziswa kwe-ultra ye-on-kunye nemhlophe

Yintoni i-dopppler iltrasound?
I-Doppler i-Ultrasound yindlela ekhethekileyo ye-ultrasound evavanya igazi lihambahamba igazi ngeenqanawa kunye nentliziyo. Isebenzisa isiphumo se-doppler, etshintsha rhoqo kwi-frequency yamaza esandi njengoko ebonakalisa izinto ezihambayo, ezinjengeeseli zegazi ezibomvu.
Isebenza njani i-doppler isebenza njani
Kwi-Doppler i-istrasound, i-transducer ikhupha amaza esandi akhupha iiseli zegazi ezihambayo. Ukuhamba kwezi seli kubangela utshintsho kwi-frequency yamaza esandi ebonakalisiweyo, efunyanwa ngumatshini we-ultrasound. Olu tshintsho kwi-frequency isetyenziselwa ukubala isantya kunye nendlela yokuhamba kwegazi, ezinokuthi ziboniswe ngokusebenzisa umbala okanye iindlela ze-doppler.
