Sib nqus resonance imaging (MRI) thev naus laus zis yog qhov tseem ceeb hauv kev muab txoj hauv kev tsis muaj kev cuam tshuam los tsim cov duab tseeb ntawm sab hauv ntawm tib neeg lub cev.Txawm li cas los xij, thev naus laus zis tsis yog yam tsis muaj kev sib tw, tshwj xeeb tshaj yog hais txog kev nyab xeeb thiab kev ua tau zoo ntawm cov txheej txheem.Ib qho tseem ceeb tshaj plaws ntawm MRI kev ruaj ntseg yog kev tiv thaiv zoo, uas siv cov ntaub ntawv xws litooj liab ntawv citiv thaiv kev cuam tshuam los ntawm lwm qhov chaw.Hauv kab lus no, peb tham txog vim li cas tooj liab siv hauv MRI thiab nws qhov zoo li cov khoom siv tiv thaiv.
Tooj liab yog ib qho khoom siv zoo tshaj plaws rau MRI shielding rau ntau qhov laj thawj.Ua ntej, nws cov conductivity siab tso cai rau nws kom nqus tau cov teeb liab electromagnetic zoo, tiv thaiv cov khoom siv los ntawm cov suab nrov sab nraud.Qhov thib ob, tooj liab yog malleable thiab malleable, yog li nws tuaj yeem tsim tau yooj yim rau hauv cov ntawv los yog cov ntawv ci uas tuaj yeem siv rau phab ntsa, qab nthab thiab cov plag tsev ntawm MRI chav.Thib peb, tooj liab tsis yog hlau nplaum, uas txhais tau hais tias nws tsis cuam tshuam nrog MRI qhov sib nqus, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau MRI shielding.
Lwm qhov txiaj ntsig tseem ceeb ntawmtooj liab ntawv cirau MRI shielding yog nws lub peev xwm los muab SF (xov tooj cua zaus) shielding.SF shielding pab nres cov nthwv dej sib nqus tawm los ntawm MRI xov tooj cua zaus coils los ntawm kev mus ncig thoob plaws hauv lub tsev, uas tuaj yeem cuam tshuam nrog lwm yam khoom siv hluav taws xob lossis ua rau muaj kev phom sij rau cov neeg nyob ib puag ncig.Txhawm rau kom nkag siab qhov no, tag nrho cov txiaj ntsig ntawm xov tooj cua zaus ntawm lub cev yuav tsum raug txiav txim siab.Txawm hais tias MRI siv cov hluav taws xob tsis-ionizing uas pom tau tias muaj kev nyab xeeb, kev cuam tshuam rau lub sijhawm ntev ntawm cov xov tooj cua zaus yuav muaj cov teebmeem lom lom.Qhov no yog vim li castooj liab ntawv ciyuav tsum tau siv los muab kev tiv thaiv SF zoo thiab muaj txiaj ntsig.
Hauv cov ntsiab lus, cov ntawv ci tooj liab yog cov khoom tseem ceeb rau MRI shielding thiab muaj ntau yam zoo.Nws yog conductive, malleable, thiab non-magnetic, ua rau nws zoo tagnrho rau absorbing electromagnetic signals tsis cuam tshuam nrog MRI teb.Tsis tas li ntawd, cov ntawv ci tooj liab muab kev tiv thaiv zoo SF uas pab tiv thaiv cov hluav taws xob hluav taws xob los ntawm kev nthuav tawm thoob plaws hauv lub tsev, txo qis kev cuam tshuam nrog cov khoom siv hluav taws xob thiab txo qhov kev pheej hmoo ntawm kev mob nkeeg los ntawm kev raug RF mus ntev.MRI cov chaw yuav tsum muaj cov khoom zootooj liab ntawv cishielding los xyuas kom meej kev saib xyuas neeg mob zoo thiab muaj kev nyab xeeb thiab txhim khu kev qha kev kuaj pom cov txiaj ntsig.
