Dab tsi yog 3D / 4D xim Doppler ultrasound?
3D xim Doppler ultrasound yog ib hom xim Doppler ultrasound, thiab 3D xim Doppler ultrasound yog peb-dimensional dynamic zaub. Qhov zoo ntawm 3D xim ultrasound yog nyob rau hauv cov nram qab no teb
① Lub rhiab heev thiab tso saib tus nqi ntawm uterine hlab ntsha thiab zes qe menyuam ntshav txaus.
② Txo lub sijhawm tshuaj xyuas thiab tau txais qhov tseeb Doppler spectrum.
③ Tsis tas yuav sau lub zais zis.
④ Tsis txhob cuam tshuam rau lub cev hom rog, plab plab, thiab plab hnyuv loj.
⑤ Nrhiav qhov sib tw ntawm lub plab hnyuv siab raum los ntawm txoj kev txav ntawm qhov kev sojntsuam kom txiav txim siab seb puas muaj adhesion nyob rau hauv lub plab mog.
3D xim ultrasound nto imaging yog siv nyob rau hauv kev kuaj obstetric, tsis yog tsuas yog los soj ntsuam cov txheej txheem ntawm fetal kev loj hlob, tab sis kuj soj ntsuam cov kev hloov nyob rau hauv lub placenta, amniotic kua thiab umbilical qaum, thiab tseem ceeb tshaj, nws yuav siv tau raws li lub ntsiab txhais tau tias kev kuaj mob. fetal malformations. Vim yog qhov sib txawv loj ntawm cov qauv ntawm cov ntaub so ntswg thiab cov kua grey theem, nws tuaj yeem pom tseeb cov duab peb sab, cov yam ntxwv ntawm qhov chaw thiab qhov chaw sib raug zoo ntawm cov qauv tsis txaus ntseeg, thiab muab cov duab peb sab ntawm tus menyuam hauv plab. Kev tsim kho 3D suav nrog kev kos duab saum npoo, pob tshab duab thiab ntau hom duab dav hlau.
3D Xim Doppler Nta
(1) Ntxiv cov duab coronal raws li khaws cia 2D duab.
(2) Stereotaxic, axis hloov kho, peb axis dav hlau ntawm ABC tuaj yeem hloov kho ntawm lub siab kom txog thaum pom cov duab zoo tshaj plaws.
(3) Stereoscopic duab, dynamic thiab intuitive; real-time dynamic kev soj ntsuam ntawm fetal lub taub hau, lub cev nto thiab cov hauv nruab nrog cev kev ua ub no, cov duab yog meej, meej thiab txhim khu kev qha.
(4) Kev ua haujlwm txiav tuaj yeem khaws cov ntsiab lus tseem ceeb ntawm daim duab; txiav tawm qhov tsis muaj txiaj ntsig, thiab ua 3D reconstruction thiab tso saib ntawm qhov tsis txaus ntseeg.
(5) Kev sib hloov ua haujlwm, uas tuaj yeem pom los ntawm ntau sab; Nrog 360 degree kev sib hloov ua haujlwm ntawm pem hauv ntej thiab nram qab, sab laug thiab sab xis, thiab nce thiab nqis, daim duab tuaj yeem pom zoo nyob rau hauv ntau cov lus qhia.
(6) Nws tuaj yeem nqa cov duab zoo nkauj ntawm tus menyuam hauv plab, sau cov kev hloov pauv thiab hlawv lub disc raws li cov ntaub ntawv khaws cia, thiab khaws cia ua lub cim xeeb ruaj khov.
(7) Kev sib raug zoo ntawm peb sab thiab kev sib raug zoo ntawm cov kab mob sib txawv tuaj yeem tshwm sim. Daim ntawv thov ntawm 3D xim ultrasound hauv obstetrics muab ntau cov ntaub ntawv duab rau kev kuaj mob ultrasound. Tus me nyuam hauv plab yog ib puag ncig los ntawm cov kua hauv cov kab noj hniav amniotic, uas yog ib qho kev pom zoo rau 3D ultrasound. Cov duab yog peb-dimensional thiab intuitive, thiab lub kaum sab xis tuaj yeem hloov kho arbitrarily. Cov qauv tsis txaus ntseeg tuaj yeem pom los ntawm kev sib hloov, thiab qhov deformity ntawm cov qauv dav dav ntawm tus menyuam hauv plab tuaj yeem pom ntawm ib nrais muag, uas ua rau muaj txiaj ntsig zoo ntawm kev kuaj mob thiab kev kho mob thiab txo qis misdiagnosis lossis tsis kuaj mob.
3D xim Doppler lub sijhawm
Feem ntau 22 mus rau 26 lub lis piam ntawm cev xeeb tub los ua peb-dimensional xim Doppler ultrasound los xyuas qhov kev loj hlob ntawm tus me nyuam hauv plab los txiav txim deformities, yog lub sij hawm zoo tagnrho.
Plaub-dimensional ultrasound
Plaub-dimensional xim ultrasound diagnostic apparatus yog lub ntiaj teb no lub siab tshaj plaws xim ultrasound khoom. "4D" yog lub ntsiab lus ntawm "plaub-dimensional". Qhov thib plaub yog hais txog lub sijhawm vector. Rau Ultrasound, 4D Ultrasound thev naus laus zis yog cov cuab yeej tsim tshiab thiab cov cuab yeej tshwj xeeb ntawm Canadian tuam txhab Yusheng. 4D ultrasound tshuab siv 3D ultrasound dluab ntxiv rau lub sij hawm dimension tsis. Lub tshuab thev naus laus zis no tuaj yeem tau txais cov duab 3D hauv lub sijhawm tiag tiag, dhau qhov kev txwv ntawm cov tsoos ultrasound. Nws muaj ntau yam kev siv xws li plab, vascular, me me, obstetrics, gynecology, urology, neonatal thiab pediatrics. Qhov tshwm sim: lub peev xwm los tso saib cov duab txav hauv lub sijhawm ntawm koj tus menyuam hauv plab, lossis lub sijhawm txav cov duab ntawm lwm tus tib neeg lub cev.
Piv nrog rau lwm cov txheej txheem kuaj mob 3D ultrasound, 4D ultrasound tso cai rau cov kws kho mob los soj ntsuam cov kev txav ntawm lub cev sab hauv ntawm tib neeg lub cev hauv lub sijhawm. Piv txwv li, cov kws kho mob tuaj yeem txiav txim siab txog kev loj hlob ntawm tus me nyuam hauv plab raws li kev txav ntawm tus me nyuam hauv plab, thiab qhov tseeb ntawm kev sib tsoo nyob rau hauv kev taw qhia ultrasound tuaj yeem txhim kho los ntawm kev soj ntsuam peb-dimensional dav hlau txav ntawm rab koob. Yog li cov kws kho mob thiab cov kws kho mob tuaj yeem kuaj pom thiab pom ntau yam txawv txav.
4D Xim Doppler Ultrasound yog ib qho kev ua tiav ultrasound rau lub mis imaging, interventional urology, thiab kev kho mob imaging. Raws li tag nrho cov khoom siv ultrasound, nws tuaj yeem siv los ua cov kev tshawb fawb hauv qab no:
◆ Kev txiav txim siab ntawm lub hnub nyoog fetal
◆ Tshawb xyuas kev loj hlob ntawm fetal
◆ Kev ntsuam xyuas ntawm ntau yam kev yug me nyuam thiab / lossis kev xeeb tub uas muaj feem pheej hmoo siab
◆ Tshawb xyuas qhov txawv txav ntawm fetus
◆ Tshawb xyuas qhov txawv txav ntawm lub tsev menyuam
◆ Tshawb xyuas qhov txawv txav ntawm qhov chaw mos
◆ Tshawb xyuas cov ntshav txawv txav
◆ Tshawb xyuas lub cev xeeb tub thiab lwm yam cev xeeb tub
◆ Tshawb xyuas cov qog ntawm zes qe menyuam thiab fibroids
◆ Qhov chaw ntawm qhov chaw mos
Nrog cov duab zoo meej, "plaub-dimensional xinesmas" plaub-dimensional xim ultrasound kuaj ntsuas rau cov niam muaj peev xwm tuaj yeem siv lub cev "duab" thiab cov yeeb yaj kiab zoo rau tus me nyuam hauv plab, ntxiv kev thaj yeeb ntawm lub siab thiab kev txaus siab rau ntau tus niam tsev.
Lawv tsis tsuas hnov tus me nyuam ua pa thiab txav mus, tab sis tuaj yeem pom lawv txhua qhov kev txav thiab coj tus cwj pwm zoo. Qhov tseem ceeb tshaj, plaub-dimensional xim Doppler ultrasound tuaj yeem soj ntsuam kev loj hlob thiab kev loj hlob ntawm tus me nyuam hauv plab hauv lub tsev menyuam los ntawm ntau cov lus qhia thiab cov ces kaum, thiab muab qhov tseeb scientific hauv paus rau kev kuaj mob ntxov ntawm fetal congenital lub cev deformities thiab congenital mob plawv. Yav dhau los, B-ultrasound cov cuab yeej tsuas tuaj yeem tshawb xyuas qhov ntsuas lub cev ntawm tus menyuam hauv plab, thaum lub sijhawm 4D xim ultrasound tuaj yeem kuaj xyuas lub cev ntawm tus menyuam hauv plab, xws li cleft di ncauj, spina bifida, hlwb, lub raum, plawv, skeletal dysplasia, etc. Kho kom sai li sai tau. Nws tsis yog kev npau suav ntxiv lawm kom muaj tus me nyuam ntse thiab noj qab nyob zoo, thiab ua kom tus menyuam lub ntsej muag thiab ua yeeb yam rau hauv cov duab lossis VCDs, kom tus menyuam muaj tag nrho 0-xyoo-laus duab album.
Tsis tas li ntawd, qhov zoo tshaj plaws ergonomic tsim ntawm plaub-dimensional xim ultrasonic diagnostic ntsuas tsis muaj nyob rau hauv hluav taws xob, lub teeb tsis thiab electromagnetic tsis, thiab tsis muaj kev cuam tshuam rau tib neeg noj qab haus huv.
