Ukuqonda i-Ultrasound

Isishwankathelo seCardiac Ultrasound:

Ukusetyenziswa kwe-ultrasound yentliziyo kusetyenziswa ukuhlola intliziyo yesigulana, izakhiwo zentliziyo, ukuhamba kwegazi, nokunye. Ukuhlola ukuhamba kwegazi ukuya nokubuya entliziyweni kunye nokuhlola izakhiwo zentliziyo ukuze kufunyanwe nawuphi na umonakalo okanye ukuvaleka zizizathu ezimbalwa eziqhelekileyo zokuba abantu bafune ukwenza i-ultrasound yentliziyo. Kukho iintlobo ngeentlobo zee-transducers ze-ultrasound ezenzelwe ngokukodwa ukubonisa imifanekiso yentliziyo, kunye noomatshini be-ultrasound abenzelwe ngokukodwa ukuvelisa imifanekiso ephezulu, i-2D/3D/4D, kunye nemifanekiso enzima yentliziyo.

Kukho iintlobo neempawu ezahlukeneyo zemifanekiso ye-cardiac ultrasound. Umzekelo, umfanekiso we-Doppler onombala ungabonisa ukuba igazi lihamba ngesantya esingakanani, ukuba lingakanani igazi elihambayo eliya okanye eliphuma entliziyweni, kwaye ukuba kukho naziphi na izithintelo ezithintela igazi ukuba lihambe apho kufanele lihambe khona. Omnye umzekelo ngumfanekiso we-2D ultrasound oqhelekileyo okwaziyo ukuhlola isakhiwo sentliziyo. Ukuba kufuneka umfanekiso ocacileyo okanye oneenkcukacha ezingaphezulu, umfanekiso we-3D/4D ultrasound wentliziyo ungathathwa.

Isishwankathelo se-Vascular Ultrasound:

Ukusetyenziswa kwe-Vascular ultrasound kunokusetyenziswa ukuhlola imithambo yegazi, ukuhamba kwegazi, kunye nemithambo yegazi naphi na emzimbeni wethu; iingalo, imilenze, intliziyo, okanye umqala zezinye zeendawo ezinokuhlolwa. Uninzi lwee-ultrasound matshini ezikhethekileyo zokusetyenziswa kwentliziyo zikwakhethekileyo zokusetyenziswa kwemithambo yegazi (yiyo loo nto igama elithi cardiovascular). I-Vascular ultrasound idla ngokusetyenziselwa ukuxilonga amahlwili egazi, imithambo yegazi evalekileyo, okanye naziphi na iingxaki ekuhambeni kwegazi.

Inkcazo ye-Vascular Ultrasound:

Inkcazelo yokwenyani ye-vascular ultrasound kukubonisa imifanekiso yokuhamba kwegazi kunye nenkqubo yokujikeleza kwegazi ngokubanzi. Ngokucacileyo, olu vavanyo alupheleli nakweyiphi na inxalenye yomzimba, njengoko igazi lihlala lihamba emzimbeni wonke. Imifanekiso yemithambo yegazi ethathwe ebuchotsheni ibizwa ngokuba yi-TCD okanye i-transcranial Doppler. I-Doppler imaging kunye ne-vascular imaging ziyafana kuba zombini zisetyenziselwa ukubonisa imifanekiso yokuhamba kwegazi, okanye ukungabikho kwayo.
