I-Dopler i-Ultrasound yindlela yokucinga esetyenziswayo esetyenziselwa kakhulu kunyango lwanamhlanje. Ngaphandle kokusetyenziswa kwayo, abantu abaninzi abaziqhelanise nokuba yintoni, yahluke njani kwi-ilrasound emiselweyo, iindidi zayo ezahlukeneyo, kunye nezicelo zayo zonyango. Eli nqaku lijolise ekunikezeleni ngokuqonda okunzulu kwe-Doppler ye-Doppler, egubungela imigaqo-siseko, iintlobo, ukusetyenziswa, kunye nokubaluleka kwendlela yokuxilongwa kwezonyango.

Yintoni i-dopppler iltrasound?

I-Doppler i-Ultrasound yindlela yokucinga engahlambululanga esebenzisa amaza esandi esiphezulu esiya kuthi abonakalise kwaye alingane ukuhamba kwegazi ngaphakathi kwempahla yomzimba. Ngokungafaniyo ne-ultrasound yesindali, ethi idala ibala imifanekiso yezakhiwo zangaphakathi, i-Doppler Ultrasound uvavanya ukuhamba kwegazi, encedisa ekuvavanyweni umsebenzi kunye nempilo yemithambo yegazi.

Ngaba i-Dopathi igqibelwa njani?

Indlela yobuchule isekwe kwimpembelelo ye-doppler, i-phenomen ebizwa ngegama lika-Austriki ka-Austrikhi ye-Austriki Christist. Isiphumo se-doppler ibhekisa kutshintsho kwi-frequency okanye i-wavelength yezandi njengoko zibonisa izinto ezihambayo. Kwi-Doppler i-istrasound, amaza esandi akhutshwa yiTransducer (isixhobo esiphathwayo esibekwe kulusu) esikhupha iiseli ezihambayo kwimpahla yegazi kwimithambo yegazi. Ukutshintsha rhoqo phakathi kokukhutshwa kunye nokufumana amaza esandi emva koko alinganiswe kwaye asetyenziselwe ukufumanisa isantya kunye nendlela yokuhamba kwegazi.

Umahluko phakathi kweDoppler Ultrasound kunye ne-Ultrasound

I-Ultraund

• Ukucingisisa kugxile: I-Ultrasound esemgangathweni, ekwabizwa ngokuba yi-B-Mode okanye imo yemozulu ye-Ultraund, igxile ekwenzeni imifanekiso emibini emilinganiselo yamalungu angaphakathi kunye nezicubu. Kusetyenziswa kakhulu ukubona ulwakhiwo lwamalungu omzimba, izihlunu, kunye nezikhubekiso ngexesha lokukhulelwa.

• Ukucingisisa okwahlukileyo

• I-Dopler iltrasound

• Ukugxila okusebenzayo: I-Doppler Iscrosound, ngokuchaseneyo, yenzelwe ngokukodwa ukulinganisa ukuhamba kwegazi ngeenqanawa. Inika ulwazi malunga ne-velocity kunye nendlela yokuhamba kwegazi, ekubaluleke kakhulu ekuvavanyeni impilo ye-vascular.

• Ukuhlaziywa rhoqo kohlalutyo: Indlela ixhomekeke ekufumaneni utshintsho kwi-frequency yamaza esandi njengoko ebonakalisa iiseli zegazi, ukuvumela uvavanyo lwezinto ezihambayo zegazi.

Iindidi zeDoppler I-Ultrasound

Zininzi iindidi ze-DOPRERRER, nganye esebenzayo ngeenjongo ezithile zokuxilonga:

• Umbala doprasor ultrasound: Umbala dopler usebenzisa ikhowudi yombala ukubonisa isantya kunye nendlela yokuhamba kwegazi ngaphakathi kweenqanawa. Imibala eyahlukeneyo (ihlala ibomvu kwaye iblowu) ibonisa indlela yokuhambahamba kwi-transducer.

      Isicelo: Olu hlobo lusetyenziswa ngokubanzi ukubona ukuhamba kwegazi kwimithambo kunye nemiphunga, chonga iibhloko, kwaye uvavanye imeko yeValves yentliziyo.

• I-Doppler ye-Doppler ye-Ulppler: I-Doppler yamandla inobuthathaka kunombala wombala kwaye ikwazi ukufumana ukuhamba kwegazi eliphantsi. Ibonisa amandla (i-amllitude) yemiqondiso ye-doppler ngaphandle kokubonisa isikhokelo, ukubonelela ngemifanekiso eneenkcukacha ezininzi zokuhamba kwegazi.

      Isicelo: I-Doppler yamandla iluncedo kakhulu ekuboneni ukuhamba kwegazi kwiinqanawa ezincinci okanye ezinzulu nasezinyokweni zegazi ezihamba kancinci, ezinjengezintso kunye nesibindi.

• I-Doppler yeDoppler ye-Depler: I-Doppler ye-Intanethi ibonisa ubugqwirha igazi njenge-velocis kwigrafu, kunye ne-axis ethe tyaba kunye ne-axis ethe nkqo emele i-velocity. Oku kuvumela umlinganiso ochanekileyo weempawu zokuhamba kwegazi.

      Isicelo: Iqhelekile isetyenziselwa ukuvavanya ukuhamba kwegazi kwiinqanawa ezinkulu kunye nokuvavanya umsebenzi we-Cardiac, kubandakanya ukuphazamiseka kwentliziyo kunye noxinzelelo lwendlebe.

• I-doppler eqhubekayo ye-doppler i-ulppleor: i-doppler eqhubekayo i-espings iqhubeka kwaye ifumana amaza esandi, avumele umlinganiso wegazi eliphezulu lokuhamba kwegazi. Ayiboneleli ngokomfanekiso, kodwa ivelisa uphawu olubonakalayo lokuvavanya ukuhamba kwegazi.

      Isicelo: Olu hlobo lulungile ekulinganiseni izinto ezihamba phambili igazi eliphezulu, ezinjengezo zifunyenwe kwiimeko ze-stenosis enkulu (yokunciphisa imithambo yegazi).

• I-Dupex Ultraund: I-Dupex Ultraund idibanisa i-B-Mode ye-B-Indlela yeDoppler i-istrasound, ibonelela ngemifanekiso yemifanekiso ye-anatomical kunye nokuhamba kwegazi kuviwo olunye.

      Isicelo: Isetyenziselwa ukuvavanya iimeko ezinje nge-verissis enzulu, isifo se-carotid isifo, kunye nesifo somthambo.
