Itekhnoloji ye-Magnetic resonance imaging (MRI) ibaluleke kakhulu ekuboneleleni ngendlela engeyiyo i-invasive yokuvelisa imifanekiso echanekileyo ngaphakathi emzimbeni womntu.Nangona kunjalo, iteknoloji ayinayo imingeni yayo, ngakumbi malunga nokhuseleko kunye nokusebenza kakuhle kwenkqubo.Enye yezona zinto zibalulekileyo zokhuseleko lwe-MRI lukhuselo olufanelekileyo, olusebenzisa izinto ezifanaifoyile yobheduukuthintela ukuphazamiseka kwimithombo yangaphandle.Kweli nqaku, sixubusha ukuba kutheni ubhedu lusetyenziswa kwi-MRI kunye neenzuzo zayo njengento yokukhusela.
Ubhedu luyinto efanelekileyo yokukhusela i-MRI ngenxa yezizathu ezininzi.Okokuqala, i-conductivity ephezulu ivumela ukuba ikwazi ukufunxa ngokufanelekileyo izibonakaliso ze-electromagnetic, ukukhusela izixhobo kwingxolo yangaphandle.Okwesibini, ubhedu luyakwazi ukunyanzeliswa kwaye lunokuguqulwa, ngoko lunokwenziwa lula kumaphepha okanye iifolthi ezinokuthi zifakwe kwiindonga, iisilingi kunye nemigangatho yamagumbi e-MRI.Okwesithathu, ubhedu aluyiyo i-magnetic, oku kuthetha ukuba ayiphazamisi intsimi yamagnetic ye-MRI, iyenza ibe yinto efanelekileyo yokukhusela i-MRI.
Enye inzuzo ebalulekileyo yeifoyile yobheduukhuselo lwe-MRI kukukwazi ukubonelela nge-SF (i-radio frequency) yokukhusela.Ukukhusela i-SF kunceda ukumisa amaza amagnetic akhutshwa yi-MRI radio frequency coils ekuhambeni kwisakhiwo sonke, esinokuphazamisana nezinye izixhobo ze-elektroniki okanye ukubeka ingozi yempilo kubantu abakummandla ongqongileyo.Ukuqonda oku, isiphumo sisonke samaza kanomathotholo kumzimba kufuneka sithathelwe ingqalelo.Nangona i-MRI isebenzisa i-non-ionizing radiation ethathwa njengekhuselekile, ukuvezwa kwexesha elide kwimimandla ye-radiofrequency kunokuba neziphumo ezibi zebhayoloji.Kungenxa yoko le ntoifoyile yobhedukufuneka isetyenziselwe ukubonelela ngokhuseleko lweSF olusebenzayo nolusebenzayo.
Isishwankathelo, i-foil yobhedu yinto ephambili yokukhusela i-MRI kwaye inikezela ngeenzuzo ezininzi.Iyaqhuba, iyasebenziseka, kwaye ayinamagnetic, iyenza ilungele ukufunxa imiqondiso yombane ngaphandle kokuphazamisana nemimandla yeMRI.Ukongeza, ifoyile yobhedu ibonelela ngokhuselo olusebenzayo lweSF olunceda ukuthintela amaza ombane ukuba angasasazeki kwisakhiwo sonke, ukunciphisa ukuphazamiseka kwezixhobo ze-elektroniki kunye nokunciphisa umngcipheko weziphumo ezibi zempilo ukusuka ekuvezweni kweRF ixesha elide.Izibonelelo ze-MRI kufuneka zibe nomgangatho ophezuluifoyile yobheduukukhusela ukuqinisekisa ukhathalelo lwesigulane kunye neziphumo ezikhuselekileyo nezithembekileyo zokuxilonga.
