Mochini oa Iseult Project oa 11.7 Tesla MRI o nkile litšoantšo tse makatsang tsa batho ba phelang. botho boko ho tsoa ho barupeluoa. Ena ke thuto ea pele ea bophelo botho boko ka mochini oa MRI oa matla a matla a khoheli a phahameng joalo a faneng ka litšoantšo tsa 0.2 mm ka sefofaneng le botenya ba 1 mm (e emelang molumo o lekanang le li-neuron tse likete tse seng kae) ka nako e khuts'oane ea ho fumana metsotso e 4 feela.
Setšoantšo sa botho boko ka qeto ena e e-s'o ka e e-ba teng ka mochini oa Iseult MRI e tla thusa bafuputsi ho utolla lintlha tse ncha tsa sebopeho le tšebetso ea botho boko e ka fanang ka leseli mabapi le hore na boko bo kenya liepiso tsa kelello joang kapa hore na matšoao a kelello ke afe. Litšibollo tse ncha li ka thusa ho hlahloba le ho alafa mafu a neurodegenerative joalo ka Alzheimer's le Parkinson's. Mochini ona o ka boela oa thusa ho lemoha mefuta ea lik'hemik'hale tse amehang ho metabolism ea boko tse ke keng tsa bonoa ke mechini ea MRI ea matla a tlase a matla a khoheli.
Sekena sena sa 11.7 Tesla MRI sa projeke ea Iseult se matla ka ho fetisisa lefatšeng botho mochine oa MRI oa 'mele oohle' me o kenngoa NeuroSpin ho CEA-Paris-Saclay. E ne e fane ka litšoantšo tsa pele ka 2021 ha e hlahloba mokopu mme e fana ka litšoantšo tse nang le qeto ea li-microns tse 400 ka litekanyo tse tharo tse netefalitseng ts'ebetso.
In botho Mekhoa ea MRI, matla a matla a khoheli ho kapa ka holimo ho 7 Tesla e bitsoa Ultra-High Fields (UHF). Li-scanner tse 7 tsa Tesla MRI li ile tsa amoheloa ka 2017 bakeng sa litšoantšo tsa boko le tse nyenyane tsa manonyeletso. Ho na le mechine e fetang lekholo ea 7 T MRI e sebetsang lefatšeng ka bophara. Pele ho katleho ea morao-rao ea 11.7 Tesla MRI scanner ea Iseult Project, 10.5 Tesla MRI Univesithing ea Minnesota e ne e le mochine o matla ka ho fetisisa oa MRI o sebetsang o hlahisang litšoantšo tsa vivo.
Morero oa French-Jeremane oa Iseult oa ho haha sekena sa 11.7 Tesla MRI se ile sa qalisoa ke French Alternative Energies and Atomic Energy Commission (CEA) ka 2000s. Sepheo e ne e le ho hlahisa 'botho mofuputsi oa boko'. Porojeke e ile ya kopanya balekane ba diindaseteri le thutong mme e nkile dilemo tse mashome a mabedi ho phethahatswa. Ke ntho e tsotehang ea theknoloji 'me e tla fetola lipatlisiso tsa boko.
Ha e ntse e tsoela pele, marang-rang a Jeremane a Ultrahigh Field Imaging (GUFI) a sebeletsa ho theha 14 Tesla ea 'mele oohle. botho Sistimi ea MRI e le sesebelisoa sa lipatlisiso tsa naha Jeremane.
