Qhov thib plaub ntawm "plaub-dimensional xim ultrasound" hais txog lub sijhawm vector, yog li nws tseem hu ua lub sijhawm tiag tiag-lub sijhawm peb-dimensional xim ultrasound. Rau ultrasound, "4D" (abbreviation rau "plaub-dimensional") ultrasound tshuab yog ib tug revolutionary breakthrough nyob rau hauv cov xim Doppler ultrasound kev lag luam. 4D ultrasound tshuab yog 3D ultrasound dluab ntxiv rau lub sij hawm dimension tsis. Lub tshuab thev naus laus zis no tuaj yeem tau txais cov duab peb sab hauv lub sijhawm tiag tiag, dhau qhov kev txwv ntawm cov tsoos ultrasound. Nws muab ntau yam kev siv xws li plab, vascular, me me, obstetrics, gynecology, urology, neonatology thiab pediatrics. Piv nrog rau lwm yam 3D ultrasonic kuaj cov txheej txheem, plaub-dimensional xim Doppler ultrasound diagnostic instrument enables kws kho mob soj ntsuam lub dynamic zog ntawm lub cev ntawm tib neeg lub cev nyob rau hauv lub sij hawm. 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 ntawm ultrasound tuaj yeem txhim kho los ntawm kev soj ntsuam lub dav hlau peb-dimensional txav ntawm rab koob.
Plaub-dimensional xim ultrasound diagnostic instrument yuav cia li nqa "duab" thiab dynamic yeeb yaj duab rau tus me nyuam hauv plab, ntxiv kev thaj yeeb ntawm lub siab thiab kev lom zem rau ntau expectant niam. Lawv tsis tsuas yog hnov tus menyuam ua pa thiab txav mus, tab sis tuaj yeem pom lawv txhua qhov txav thiab lub ntsej muag ntxim hlub. Thiab tuaj yeem ua rau tus menyuam qhov tsos thiab ua rau hauv cov duab lossis VCD. Qhov tseem ceeb tshaj, plaub-dimensional xim Doppler ultrasound diagnostic instrument tuaj yeem soj ntsuam kev loj hlob thiab kev loj hlob ntawm tus me nyuam hauv plab hauv tsev menyuam los ntawm ntau cov lus qhia thiab cov ces kaum. Yav dhau los, B-ultrasound cov cuab yeej tsuas tuaj yeem tshawb xyuas qhov ntsuas lub cev ntawm tus menyuam hauv plab, tab sis plaub-dimensional xim Doppler ultrasound muaj lub sijhawm tiag tiag peb-dimensional imaging muaj nuj nqi thiab kev daws teeb meem siab, thiab tuaj yeem ua qhov kev kuaj xyuas antenatal fetal abnormality ntawm lub sijhawm. tus me nyuam hauv plab, xws li lub ntsej muag deformities, lub paj hlwb deformities, cov kab mob hauv nruab nrog cev, kab mob hauv lub plawv, kab mob achondroplasia, thiab lwm yam., txhawm rau kho sai li sai tau, lossis xav txog seb puas yuav txiav cev xeeb tub. Tsis tas li ntawd, qhov zoo tshaj plaws ergonomic tsim ntawm plaub-dimensional xim Doppler ultrasound diagnostic instrument tsis muaj hluav taws xob, lub teeb nthwv dej, thiab hluav taws xob nthwv dej, thiab tsis muaj kev cuam tshuam rau tib neeg kev noj qab haus huv.
Lub sijhawm zoo tshaj plaws rau plaub-dimensional xim Doppler ultrasound kuaj:
1. Plaub-dimensional xim Doppler ultrasound tuaj yeem ua tau thaum cev xeeb tub txhua lub lim tiam, thiab lub sijhawm zoo tshaj plaws yog (22-24) lub lis piam.
2. Tom qab 16 lub lim tiam ntawm cev xeeb tub, cov ceg thiab cov plab hnyuv siab raum tau loj hlob tag nrho. Lub sijhawm zoo tshaj plaws los kuaj xyuas yog ze li 24 lub lis piam, thiab cov kua amniotic yog qhov tsim nyog rau kev kuaj xyuas tus menyuam hauv plab.
Plaub-dimensional xim Doppler ultrasound soj ntsuam cov ntsiab lus:
1. Thaum ntxov thiab nruab nrab cev xeeb tub 11-14 lub lis piam gestational soj ntsuam cov khoom: fetal taub hau thiab intracranial qauv, lub ntsej muag, caj dab, plaub-chambered lub plawv, plab, zais zis, plab phab ntsa thiab umbilical qaum txuas, txha nraub qaum, ceg.
2. 22-24 lub lis piam kuaj cev xeeb tub: lub taub hau: pob txha taub hau, lub hlwb, lub hlwb midline, lateral ventricle, medulla cistern. Lub ntsej muag: daim di ncauj. Lub plawv: Plaub-chamber saib. Pob txha: Cov kev taw qhia thiab kev sib dhos ntawm vertebrae. Lub plab: kev ncaj ncees ntawm lub plab phab ntsa, daim siab, plab, ob lub raum, zais zis. Limbs: cov pob txha ntev (tsis suav nrog tus naj npawb ntawm tes, taw thiab ntiv tes thiab ntiv taw), fetal umbilical cord structure thiab nws qhov chaw txuas.
