Maiging resonance imaging, eo hangata e bitsoang MRI, ke mokhoa o sa hlaseleng o sebelisoang haholo ke litsebi tsa bophelo bo botle ho bona sebopeho sa 'mele oa kahare.MRI e sebelisa matla a khoheli a matla le maqhubu a seea-le-moea ho etsa litšoantšo tse qaqileng tsa litho tsa ’mele, lisele le masapo.
Mabapi le mochine oa MRI, potso e atisang ho hlaha likelellong tsa batho ke hore na ke hobane'ng ha kamore ea MRI e lokela ho kenngoa ka koporo?Karabo ea potso ena e itšetlehile ka melao-motheo ea electromagnetism.
Ha mochine oa MRI o buletsoe, o hlahisa matla a khoheli a matla a ka amang lisebelisoa le litsamaiso tsa elektronike tse haufi.Ho ba teng ha matla a khoheli ho ka sitisa lisebelisoa tse ling tsa elektronike tse kang lik’homphieutha, lifono le thepa ea bongaka, ’me ho ka ba ha ama le tšebetso ea li- pacemaker.
Ho sireletsa lisebelisoa tsena le ho boloka botšepehi ba lisebelisoa tsa litšoantšo, kamore ea MRI e kenngoafoil ea koporo, e sebetsang e le tšitiso ea matla a khoheli.Koporo e sebetsa haholo, ho bolelang hore e monya le ho hasanya matla a motlakase, 'me e sebetsa hantle ho boneseng kapa ho sireletsa matla a khoheli.
Lesela la koporo hammoho le foam e sireletsang le plywood li etsa lesaka la Faraday ho potoloha mochine oa MRI.Faraday cage ke sebaka se kampetsoeng se etselitsoeng ho thibela masimo a motlakase le ho thibela tšitiso ea lisebelisoa tsa elektroniki.Cage e sebetsa ka ho aba tefiso ea motlakase ka ho lekana ka holim'a lesaka, 'me ka nepo e fokotsa libaka tse kantle tsa motlakase.
Foil ea koporoha e sebelisetsoe ho sireletsa feela, empa hape le ho thea fatše.Mechine ea MRI e hloka hore maqhubu a phahameng a fetisoe ka likhoele tse hlahisang matla a khoheli.Maqhubu ana a ka etsa hore ho be le motlakase o tsitsitseng o ka senyang thepa esita le ho ba kotsi ho bakuli.Foil ea koporo e behoa maboteng le fatše ea kamore ea MRI ho fana ka tsela ea hore tefiso ena e tsoe ka mokhoa o sireletsehileng fatše.
Ho phaella moo, ho sebelisa koporo e le thepa ea tšireletso ho fana ka melemo e mengata ho feta mekhoa e tloaelehileng ea ho sireletsa.Ho fapana le loto, koporo e bonolo ho bōptjoa 'me e ka etsoa habonolo ka libopeho le boholo bo sa tšoaneng ho finyella litlhoko tse khethehileng tsa kamore ea MRI.E boetse e na le litšenyehelo tse ngata le ho boloka tikoloho ho feta loto.
Qetellong, likamore tsa MRI li na le foil ea koporo ka mabaka a utloahalang.Thepa ea tšireletso eafoil ea koporosireletsa lisebelisoa tsa ho nka litšoantšo tšitisong ea motlakase ea kantle ha u ntse u netefatsa polokeho ea mokuli le basebetsi.Foil ea koporo e kopantsoe le lisebelisoa tse ling ho etsa cage ea Faraday e nang le matla a khoheli a hlahisoang ke mochine oa MRI ka mokhoa o sireletsehileng le o laoloang.Copper ke conductor e ntle haholo ea motlakase, 'me e sebelisoafoil ea koporoe etsa bonnete ba hore mochine oa MRI o thehiloe hantle.Ka lebaka leo, tšebeliso ea foil ea koporo ka tšireletso ea MRI e fetohile mokhoa o tloaelehileng ho pholletsa le indasteri ea bongaka, 'me ka mabaka a utloahalang.
