Sib nqus resonance imaging (MRI) yog ib qho tseem ceeb tshaj plaws ntawm kev kho mob niaj hnub no.Nws siv cov hlau nplaum muaj zog thiab cov xov tooj cua zaus kom tsis txhob nkag mus rau cov duab sib luag ntawm tib neeg cov ntaub so ntswg, ua lub luag haujlwm tseem ceeb hauv kev kuaj mob ntau yam.Txawm li cas los xij, ib txwm siv MRI scanners muaj cov qauv tubular kaw, yuam cov neeg mob pw hauv qhov nqaim thaum kuaj.Qhov no ua rau muaj kev ntxhov siab loj heev, tshwj xeeb tshaj yog rau cov menyuam yaus, cov laus, thiab cov neeg mob uas muaj claustrophobia, vim tias pw hauv qhov chaw kaw yuav tsis xis nyob heev.Tsis tas li ntawd, lub suab nrov yog tsim tawm tsis tu ncua thaum MRI scans, ntxiv rau cov neeg mob tsis xis nyob.Qhib MRI scanners yog li tsim los txhim kho cov neeg mob kev paub zoo.
Qhov loj tshaj plaws ntawm kev qhib MRI yog nws cov hlau nplaum C-shaped lossis O-shaped uas tsim kom muaj kev nkag mus rau ob sab ntawm lub bore.Cov neeg mob tau muab tso rau hauv qhov qhib kom lawv tuaj yeem pom qhov chaw sab nraud es tsis txhob muab kaw rau hauv qhov chaw nqaim.Qhov no zoo heev alleviates tus neeg mob kev ntxhov siab vim thiab kev xav ntawm kev kaw.Tsis tas li ntawd, qhib kev nkag MRI tsuas yog ib ncig ntawm 70 decibels ntawm lub suab nrov, 40% txo los ntawm 110 decibels ntawm ib txwm kaw MRI scanners, tso cai rau cov txheej txheem scanning zoo dua.

Nyob rau hauv cov nqe lus ntawm lub cev Cheebtsam, qhib MRI khaws cov tseem ceeb ntawm ib tug qauv MRI scanner, nrog rau cov hlau nplaum tseem ceeb uas ua rau ib tug muaj zog zoo li qub magnetic teb, gradient coils uas tsim gradient teb, thiab RF coils rau excitation thiab teeb liab ntes.Lub zog ntawm cov hlau nplaum tseem ceeb hauv qhib MRI tseem tuaj yeem ncav cuag 0.2 txog 3 Tesla, nrog rau cov pa MRI.Qhib MRI kuj tseem suav nrog cov qauv kev txhawb nqa neeg mob ntxiv thiab cov txheej txheem docking kom haum rau qhov qhib kev teeb tsa thiab cov neeg mob qhov yuav tsum tau ua.Zuag qhia tag nrho, thaum txhim kho cov neeg mob kev paub dhau los, qhib MRI khaws cov ntsiab lus tseem ceeb ntawm kev sib nqus resonance imaging thiab tseem tuaj yeem muab cov duab zoo ntawm tib neeg cov ntaub so ntswg.
Piv rau ib txwm kaw MRI, qhib MRI muaj qhov zoo hauv qab no:
1. Zoo heev txo kev ntshai claustrophobic.Kev tsim qauv qhib ua kom cov neeg mob tsis txhob hnov qab nyob hauv lub qhov nqaim, muab qhov chaw nyob ntsiag to tshwj xeeb tshaj yog rau cov menyuam yaus, cov neeg laus, lossis cov neeg mob claustrophobic.Qhov no txhim kho kev ua raws cai thiab tso cai rau kom tau txais cov txiaj ntsig zoo tshaj plaws.
2. txo suab nrov, tso cai rau kev soj ntsuam zoo dua.Qhib MRI suab nrov yog kwv yees li 40% qis dua lub kaw lus kaw.Lub suab nrov txo txo cov neeg mob kev ntxhov siab, tso cai rau lub sij hawm luam ntawv ntev dua thiab xav paub ntau ntxiv txog cov duab kos.
3. Yooj yim dua thiab siv tau rau txhua tus neeg mob.Qhov qhib nkag thiab txo cov suab nrov ua rau kev tshuaj ntsuam xyuas yooj yim rau cov neeg siv lub rooj zaum hauv lub rooj zaum, cov neeg mob lub cev, lossis cov neeg muaj teeb meem kev txav mus los.Qhib MRI scanners tuaj yeem tshawb xyuas cov neeg mob ncaj qha yam tsis muaj kev hloov pauv ntawm lub cev thiab puas siab puas ntsws.
4. Ua kom muaj kev cuam tshuam cov ntawv thov.Kev tsim qauv qhib muab kev yooj yim rau cov neeg mob thaum kuaj xyuas, ua kom yooj yim rau cov txheej txheem kev cuam tshuam MRI.Cov kws kho mob tuaj yeem ua haujlwm ntawm cov neeg mob lub sijhawm tiag tiag thaum tsis tu ncua ntsuas thaj chaw kho mob.
Muaj qee qhov kev txwv ntawm qhib MRI piv rau cov txheej txheem kaw:
1. Cov duab zoo yuav qis dua me ntsis, tshwj xeeb tshaj yog nyob rau hauv cov ntaub so ntswg sib piv thiab kev daws teeb meem.Cov qauv qhib txhais tau hais tias cov hlau nplaum sib nqus yog qhov tsis sib xws ntau dua li cov thooj voos kheej kheej kaw, ua rau degraded gradient linearity thiab qis dua cov duab kawg.Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv qis qis qis qhib MRI scanners.Muaj zog 1.5T lossis 3T qhib scanners tuaj yeem them nyiaj rau qhov tsis sib xws nrog cov shimming siab heev thiab kev tsim qauv mem tes.Tab sis theoretically, cov thooj voos kheej kheej ib txwm ua kom zoo dua thiab ua kom zoo dua qub.
2. Kev ua haujlwm tsis zoo rau cov neeg mob rog vim muaj ntau qhov sib nqus sib nqus.Cov neeg mob rog rog muaj lub cev loj dua, thiab qhib tsim tawm tsam kom tswj hwm qhov sib nqus ntawm qhov sib nqus ntawm lawv.Ib txwm muab kaw nrog MRI scanners tsuas yog yuav tsum tau ua kom zoo dua qhov sib npaug ntawm qhov chaw me me cylindrical qhov, ua tiav cov txiaj ntsig zoo rau cov neeg mob loj.Tab sis qhib MRI cov neeg muag khoom tau ua haujlwm rau cov kev daws teeb meem xws li kev qhib cov neeg mob dav dua thiab cov chaw muaj zog tshaj plaws los daws qhov kev txwv no.
3. Ntau cov qauv tsim ua rau tus nqi siab dua ntawm kev yuav khoom thiab kev saib xyuas.Kev tsim qauv qhib yuav tsum muaj cov hlau nplaum nyuaj dua thiab cov gradient coil geometries, nrog rau cov neeg mob kho cov txheej txheem.Qhov kev tsim kho ntau ntxiv no txhais tau ntau dua tus nqi pib piv rau cov hlau nplaum cylindrical uas muaj zog sib npaug.Ntxiv mus, cov duab tsis zoo ntawm cov hlau nplaum qhib MRI ua rau lawv nyuaj rau qhov chaw nyob hauv tsev kho mob cov tsev kho mob uas twb muaj lawm tsim los rau hauv MRI bores.Kev saib xyuas mus sij hawm ntev thiab helium refills kuj raug nqi ntau dua vim qhov kev cai ntawm qhib MRI systems.Tab sis rau cov neeg mob uas tau txais txiaj ntsig zoo los ntawm kev tsim qauv qhib, cov nqi ntxiv no tuaj yeem tsim nyog.
Hauv cov ntsiab lus, qhib architecture MRI scanners kov yeej qhov tsis muaj zog ntawm cov kab ke MR ib txwm muaj thiab txhim kho cov neeg mob kev nplij siab thiab kev lees paub.Lawv muab ib puag ncig scanning tus phooj ywg zoo rau cov neeg mob ntau dua.Nrog kev nce qib txuas ntxiv, qhib MRI yuav pom kev siv dav hauv kev kho mob, tshwj xeeb tshaj yog rau cov neeg mob ntxhov siab, menyuam yaus, cov neeg laus, thiab cov neeg mob tsis muaj zog.
