Ua lawe ʻo Iseult Project's 11.7 Tesla MRI i nā kiʻi anatomical kupaianaha o ke ola kanaka lolo mai nā mea komo. ʻO kēia ka haʻawina mua o ke ola kanaka ka lolo e ka mīkini MRI o ia kiʻekiʻe magnetic kahua ikaika i hāʻawi i nā kiʻi o 0.2 mm i loko o ka mokulele hoʻonā a me 1 mm ʻāpana mānoanoa (e hōʻike ana i ka leo e like me kekahi mau kaukani neurons) i loko o kahi manawa kūʻai pōkole o 4 mau minuke.
ʻO ke kiʻi kiʻi o kanaka ka lolo ma kēia hoʻoholo i ʻike ʻole ʻia e ka mīkini Iseult MRI e hiki ai nā mea noiʻi e wehe i nā kikoʻī hou a me ka hana o kanaka ka lolo Hiki ke hoʻomālamalama i ke ʻano o ka lolo e hoʻopili ai i nā hiʻohiʻona noʻonoʻo a i ʻole nā hōʻailona neuronal o ka ʻike. Hiki i nā mea hou ke kōkua i ka ʻike a me ka mālama ʻana i nā maʻi neurodegenerative e like me Alzheimer a me Parkinson. Hiki i kēia mīkini ke kōkua i ka ʻike ʻana i nā ʻano kemika e pili ana i ka metabolism o ka lolo i hiki ʻole ke ʻike ʻia e nā mīkini MRI o ka ikaika haʻahaʻa magnetic.
ʻO kēia 11.7 Tesla MRI scanner o ka papahana Iseult ka mea ikaika loa o ka honua kanaka mīkini MRI kino holoʻokoʻa a hoʻokomo ʻia ma NeuroSpin ma CEA-Paris-Saclay. Ua hoʻopuka ʻo ia i nā kiʻi mua i ka makahiki 2021 i ka nānā ʻana i ka paukena a hāʻawi i nā kiʻi me kahi hoʻonā o 400 microns i ʻekolu mau ʻāpana i hōʻoia i ke kaʻina hana.
In kanaka ʻO nā ʻōnaehana MRI, ʻoi aku ka ikaika o ke kahua magnetic ma luna a i ʻole 7 Tesla i kapa ʻia ʻo Ultra-High Fields (UHF). Ua ʻae ʻia ʻo 7 Tesla MRI scanners ma 2017 no ka lolo a me nā kiʻi liʻiliʻi liʻiliʻi. Aia ma luna o hoʻokahi haneli 7 T MRI mīkini e hana ana ma ka honua holoʻokoʻa. Ma mua o ka lanakila hou o 11.7 Tesla MRI scanner o Iseult Project, 10.5 Tesla MRI ma ke Kulanui o Minnesota ʻo ia ka ikaika kiʻekiʻe loa o ka mīkini MRI i ka hana ʻana i nā kiʻi vivo.
Ua hoʻokumu ʻia ka French-German Iseult Project no ke kūkulu ʻana i kahi 11.7 Tesla MRI scanner e ka French Alternative Energies and Atomic Energy Commission (CEA) ma 2000s. ʻO ka pahuhopu e hoʻomohala i kahi 'kanaka ʻimi ʻimi lolo'. Ua hui pū ka papahana i nā hoa hana ʻenehana a me ka hoʻonaʻauao a ua hala ʻelua mau makahiki i ka hopena. He mea kupanaha ʻenehana a e hoʻololi hou i ka noiʻi lolo.
Ke holomua nei, ke hana nei ka pūnaewele German Ultrahigh Field Imaging (GUFI) i ka hoʻokumu ʻana i kahi kino holoʻokoʻa 14 Tesla. kanaka ʻO ka ʻōnaehana MRI ma ke ʻano he kumu noiʻi aupuni ma Kelemānia.
