vim li cas peb xaiv 4D Ultrasound Diagnosis System?
Hauv cov voj voog kho mob, 4D daim duab yog hais txog lub tswv yim ntxiv lub sijhawm rau cov duab peb-seem, piv txwv li cov duab digital stereoscopic.
Cov kws kho mob xav tau ultrasound los muab cov ntaub ntawv ntau dua, thiab 4D ultrasound tuaj yeem ua lub luag haujlwm tseem ceeb, vim tias kev kuaj 2D yuav tsis muaj peev xwm ua kom tau ntau cov ntaub ntawv anatomical, thiab 4D ultrasound duab txo qhov kev pheej hmoo no. 4D thev naus laus zis tuaj yeem ua tiav cov ntaub ntawv anatomical rau ntau cov chaw kuaj mob nrog tsuas yog kuaj ib zaug xwb. Raws li cov pov thawj hauv tsev kho mob maj mam ua pov thawj tias cov txuj ci zoo ntawm 4D thev naus laus zis yog ntseeg tau, cov kws kho mob yuav zoo siab txais yuav nws.
Feem ntau hais lus, cov neeg muaj feem cuam hluav taws xob feem ntau txhawm rau txhawm rau txhawm rau thiab xav tau kev tshawb fawb ua ntej ua cov chaw kho mob tshiab tau txais dav dav. Tau ntau xyoo, 4D thev naus laus zis tau nyob hauv kev sim kho mob, thiab tsis ntev los no tau txais cov pov thawj hauv chaw kuaj mob hais tias kev sojntsuam tib neeg tsis suav nrog cov ntaub ntawv, kom ntseeg tau tias kev sau thiab ua tiav ntawm txhua cov ntaub ntawv, thiab thaum kawg ua tiav kev kuaj mob sai dua thiab raug.
Piv txwv li, thaum 4D daim duab txhim kho yog siv rau kev xoos thaij duab, 4D fetal ultrasound qhia tau zoo heev rau kev muaj peev xwm ua rau kev tsis tuaj yeem ntawm cov me nyuam hauv lub hlwb thiab lwm cov ntsiab lus ntawm cov me nyuam hauv plab. Hauv kev tshwj xeeb, raws li xibfwb qhia ntawv Anders Selbing' kev tshawb fawb, 4D cov duab yuav siv tau los soj ntsuam kom zoo dua cov qauv ntawm tus menyuam lub hlwb tom qab pob txha taub hau ze rau tom teb.
Ib qho ntxiv, xibfwb Boris Tutschek nthuav tawm qhov zoo thiab qhov yuav tsum tau ua ntawm thov siv stereoscopic ultrasound rau kev tshawb nrhiav cov menyuam hauv lub hlwb ntawm International Association ntawm Obstetrics thiab Gynecology (ISUOG) lub rooj sib tham txhua xyoo. Professor Tutschek xaus lus tias" 4D thev naus laus zis tso cai rau cov chaw zoo rau kev soj ntsuam, kev kawm txog kev sib raug zoo ntawm txhua qhov taw tes hauv lub hlwb hauv ob lossis peb (orthogonal) cov dav hlau," thiab" tuaj yeem ua tiav tomography (piv rau MR thiab CT)." Ntxiv rau, los ntawm kev txheeb xyuas tus yam ntxwv ntawm cov voxels uas nyob ib sab, 4D txhim kho duab yog tiav ntawm kev txais 3D.
