Kujambula kwa ultrasound ndi kujambula kwamtundu wa Doppler ultrasound?
Pafupifupi zaka 20 zapitazo, apainiya ena amene anadzipereka kuyambitsa njira zophunzitsira za ultrasound za mayiko akunja, makamaka ochokera ku United States, anapeza mafunso angapo ochita kuyezetsa ntchito ku North America kudzera m’njira zosiyanasiyana.Funso limodzi lalifupi loyankha: Kodi pali kusiyana kotani pakati pa COLORULTRASONOGRAPHYndi COLOR DOPPLER ULTRASONOGRAPHY?
Kodi pali kusiyana kotani pakati pa kujambula kwa ultrasound ndi mtundu wa Doppler ultrasound imaging?
Kujambula kwa mtundu wa Doppler ultrasound kutangolowa ku China, kumatchedwa "color ultrasound".Madokotala aku China a ultrasound nthawi zonse amafananiza mtundu wa ultrasound ndi mtundu wa Doppler ultrasound, kotero China idawona vutoli koyamba.Madotolo adawoneka osokonezeka ndipo samadziwa kuti funsoli limafunsa chani.
Kwenikweni, ili ndi funso losavuta.
Colour ultrasound imatanthawuza kuwonetsa chidziwitso cha echo pakuwunika kwa ultrasound ndi malamulo apadera amitundu, omwe ndi kujambula kwamtundu wa ultrasound.Izi zenizeni za echo zitha kukhala mphamvu ya echo, kusuntha kwafupipafupi kwa Doppler, kuuma zambiri, chidziwitso cha microbubble, ndi zina zambiri.
choncho.Kujambula kwamtundu wa Doppler ndi imodzi mwamitundu yambiri yojambulira mitundu.Imachotsa zidziwitso zakusintha kwa pafupipafupi kwa Doppler kuchokera pazambiri za echo ndikuziwonetsa ngati mawonekedwe amitundu.
Kuphatikiza pa kujambula kwamtundu wa Doppler komwe timadziwa, tiyeni tiwone mitundu yojambula yamtundu wa ultrasound.
Tikudziwa kuti ma ultrasound amitundu iwiri imvi amawonetsa kulimba kwa siginecha ya echo ngati mawonekedwe a encoding yowala.Ngati tisankha malo enaake kapena kuwala konse, tidzapeza chithunzi chamitundu.
Pamwamba: Malo enaake mu siginecha yotuwa amasungidwa mu utoto wofiirira (muvi wotseguka), ndipo chotupa chokhala ndi kuwala kofananira chimakhala chofiirira (chowonetsedwa ndi muvi wolimba).
Njira yojambulira yomwe ili pamwambapa yomwe imatsimikizira kukula kwamitundu kapena mitundu yosiyanasiyana inali yotchuka kwambiri ku China kwakanthawi koyambirira kwa zaka za m'ma 1990.Amatchedwa "2Dpseudo-mtundukujambula" panthawiyo. Ngakhale kuti mapepala ambiri adasindikizidwa panthawiyo, kwenikweni Mtengo wogwiritsira ntchito ndi wochepa kwambiri. Panthawiyo, zipatala zambiri zinagwiritsanso ntchito chithunzichi kuti chikhale chojambula cha mtundu wa Doppler kulipiritsa odwala "chindapusa cha ultrasound". Zinalidi zopanda manyazi.
M'malo mwake, zizindikiro zonse zamitundu pamajambula amtundu wa ultrasound ndi mitundu yabodza, ndipo ma sign amtunduwa amalembedwa mwachinyengo ndikuyikidwa ndi ife.
Ambiri opangaultrasonic elastography, yomwe panopa ikudziwika kwambiri, imasonyezanso kuuma (kapena zotanuka modulus) za minofu kapena zotupa mu mawonekedwe amtundu wamtundu, kotero ndi mtundu wa mtundu wa ultrasound.
Pamwambapa: Shear wave elastography ikuwonetsa zotanuka moduli ya chotupa muzolemba zamitundu.
Pamene tinthu tating'onoting'ono tating'ono tating'ono taphulika, mphamvu yosagwirizana ndi mzere imapangidwa, zomwe nthawi zambiri sizimalumikizana bwino ndi mphamvu ya echo.Timatcha njira iyi yochotsera zidziwitso zosagwirizana ndi kujambula zithunzi zosalumikizana.Kujambula kosagwirizana kumagwiritsidwa ntchito makamaka powonetsa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono ta ultrasound timathandiza kwambiri pa kafukufuku wa ultrasound.Kawirikawiri, kusagwirizana kumeneku kumawonetsedwanso mu mawonekedwe amtundu wamtundu, kotero ndi chithunzi cha mtundu.
Pamwambapa: kujambula koyang'ana kwa p-selectin microbubble kumawonetsa kukweza kwa khoma lakunja pambuyo pa ischemia, ndi zithunzi zapamtima zowoneka bwino zapamtima kumanzere chakumanzere ndikutsika kwa ischemia mu mbewa.
(A) Ma Ultrasound of Myocardial Conhanced-enhanced akuwonetsa kuwonongeka kwapambuyo (muvi) panthawi ya myocardial ischemia.
(B) Pambuyo pa mphindi 45 zobwerezabwereza.Kukula kwamtundu kumayimira kuchulukira kwa zithunzi zosalumikizana za ma microbubble omwe akulunjika.
Kujambula kwa vector ya magazi m'munsimu ndi mtundu wa ultrasound imaging mode
