Kuyini i-Doppler Imaging?

Ukuthwebula izithombe nge-Ultrasound Doppler kuyikhono lokuhlola nokukala ukugeleza kwegazi emithanjeni ehlukahlukene, emithanjeni, nasemithanjeni. Ngokuvamile okumelelwa isithombe esinyakazayo esikrinini sohlelo lwe-ultrasound, umuntu angakwazi ukubona ukuhlolwa kwe-Doppler kusukela ekugelezeni kwegazi okunemibala okubonakala esithombeni se-ultrasound. I-Doppler ingachaza imibala esithombeni ngokusekelwe ekulinganiseni ukugeleza kwegazi endaweni ethile ethathwayo.

Ukuthwebula izithombe ze-Doppler kuhlukile ekuthwebuleni izithombe ze-ultrasound zendabuko ngendlela eyodwa eyisisekelo: empeleni akubonisi noma yisiphi isakhiwo. I-ultrasound yendabuko inikeza izithombe zezakhiwo ezahlukene, izitho zomzimba, kanye nemithambo yegazi ukuze kutholakale ukukhula, ukuphuka, izinkinga zesakhiwo, kanye nezinye izimo eziningi ezingaba khona. Ngakolunye uhlangothi, ukuthwebula izithombe ze-Doppler kubonisa kuphela isithombe sokugeleza kwegazi.

Ukuthwebula izithombe nge-Ultrasound Doppler kuyindlela eyaziwayo emhlabeni wonke futhi ehlonishwa kakhulu ngenxa yokuthi ayihlaseli futhi ayisebenzisi imisebe. I-Doppler ayisebenzisi imisebe noma izici zokuhlasela, kodwa isebenza ngendlela efanayo namanye amadivayisi okuthwebula izithombe nge-ultrasound; isebenzisa amaza omsindo aphezulu aboniswa futhi aguqulwe abe imibala, izithombe, kanye nokunyakaza okuhlukahlukene.

Izinsizakalo Zokuthwebula Izithombe Zama-Doppler:

Ukuthwebula izithombe ze-Doppler kuhlukile ekuthwebuleni izithombe ze-ultrasound zendabuko ngendlela eyodwa eyisisekelo: empeleni akubonisi noma yisiphi isakhiwo. I-ultrasound yendabuko inikeza izithombe zezakhiwo ezahlukene, izitho zomzimba, kanye nemithambo yegazi ukuze kutholakale ukukhula, ukuphuka, izinkinga zesakhiwo, kanye nezinye izimo eziningi ezingaba khona.

Ngakolunye uhlangothi, i-Doppler imaging isetshenziselwa ukuthola ukugeleza kwegazi kanye nezingozi ezahlukahlukene ezingase zenzeke emithanjeni, emithanjeni, nasemithanjeni yegazi. I-Doppler imaging ivame ukusetshenziselwa ukuthola amahlule egazi, ukuhlonza ama-valve angasebenzi kahle emithanjeni, ukunquma ukuthi imithambo ivinjiwe yini, noma ukuhlonza ukwehla kokujikeleza kwegazi emzimbeni wonke. Zonke lezi zinsongo ezingaba khona empilweni nasekuphileni zingabonwa futhi zivinjelwe nge-Doppler imaging.

Abantu basebenzisa i-Doppler imaging ngezinhlelo ezahlukene: Isibonelo, i-cardiac Doppler, ehlola ukugeleza kwegazi eliya neliphuma enhliziyweni, iyingxenye evamile futhi ebaluleke kakhulu yokuhlolwa kwesifo senhliziyo.

Ezinye izinhlelo zokusebenza ze-Doppler ezidumile zifaka phakathi i-transcranial Doppler (ukulandelela ukugeleza kwegazi ebuchosheni nasekhanda), i-vascular Doppler, kanye ne-general venous and arterial Doppler.
