Umatshini we-Iseult Project we-11.7 Tesla MRI uthathe imifanekiso emangalisayo yengqondo yomntu ephilayo kubathathi-nxaxheba. Olu luphononongo lokuqala lwengqondo yomntu ephilayo ngumatshini we-MRI onamandla amakhulu e-magnetic field oluye lwavelisa imifanekiso yesisombululo se-0.2 mm ngaphakathi kunye nobukhulu besilayi se-1 mm (emele umthamo olingana nee-neurons ezimbalwa) ngexesha elifutshane lokufumana imizuzu emi-4 kuphela.
Ukufotwa kwengqondo yomntu kwesi sisombululo singazange sibonwe ngaphambili ngumatshini we-Iseult MRI kuya kwenza abaphandi bakwazi ukufumanisa iinkcukacha ezintsha zesakhiwo kunye nokusebenza kwengqondo yomntu ezinokukhanyisa indlela ingqondo ebhala ngayo imbonakalo yengqondo okanye ukuba zeziphi iimpawu ze-neuronal zokuqonda. Izinto ezintsha ezifunyenweyo zinokunceda ekuxilongeni nasekunyangeni izifo ze-neurodegenerative ezifana ne-Alzheimer's kunye ne-Parkinson's. Lo matshini unokunceda ekufumaneni iintlobo zeekhemikhali ezibandakanyeka kwi-metabolism yengqondo ezingenakufunyanwa ngenye indlela ngoomatshini be-MRI abanamandla aphantsi e-magnetic field.
Le projekthi ye-Iseult scanner ye-Tesla MRI eyi-11.7 yeyona mashini ye-MRI enamandla kakhulu emhlabeni yomntu kwaye ifakwe kwi-NeuroSpin e-CEA-Paris-Saclay. Yayithumele imifanekiso yokuqala ngo-2021 xa yayiskena ithanga kwaye yanika imifanekiso enesisombululo se-400 microns kwiimilinganiselo ezintathu, nto leyo eyaqinisekisa le nkqubo.
Kwiinkqubo ze-MRI zabantu , amandla e-magnetic field kwi-7 okanye ngaphezulu kwe-7 Tesla ibizwa ngokuba yi-Ultra-High Fields (UHF). Ii-scanner ze-Tesla MRI ezi-7 zavunywa ngo-2017 kwimifanekiso yengqondo kunye namalungu amancinci. Kukho oomatshini be-MRI abangaphezu kwekhulu abasebenzayo kwihlabathi liphela. Ngaphambi kwempumelelo yakutshanje ye-11.7 Tesla MRI scanner ye-Iseult Project, i-10.5 Tesla MRI kwiYunivesithi yaseMinnesota yayiyeyona mashini ye-MRI enamandla kakhulu ekusebenzeni evelisa imifanekiso ye-vivo.
Iprojekthi ye-Iseult yaseFransi-yaseJamani yokwakha iskena se-Tesla MRI esingu-11.7 yasungulwa yiFrench Alternative Energies and Atomic Energy Commission (CEA) kwiminyaka yoo-2000. Injongo yayikukuphuhlisa ' umhloli wobuchopho bomntu '. Le projekthi yadibanisa amaqabane emizi-mveliso kunye nezemfundo kwaye ithathe amashumi amabini eminyaka ukuba iphumelele. Ngummangaliso wetekhnoloji kwaye uza kutshintsha uphando lobuchopho.
Inkqubela phambili, inethiwekhi yeGerman Ultrahigh Field Imaging (GUFI) isebenza ekusekeni inkqubo ye-MRI yomntu yeTesla eyi-14 njengomthombo wophando wesizwe eJamani.
