Umatshini we-Iseult Project's 11.7 Tesla MRI umatshini uthathe imifanekiso ephawulekayo ye-anatomical yokuphila umntu ingqondo evela kubathathi-nxaxheba. Esi sisifundo sokuqala sokuphila umntu ngengqondo ngomatshini we-MRI wamandla ombane aphezulu oye wavelisa imifanekiso ye-0.2 mm kwisisombululo senqwelomoya kunye nobukhulu besilayi se-1 mm (emele umthamo olingana namawaka ambalwa e-neurons) ngexesha elifutshane lokufunyanwa kwemizuzu emi-4 kuphela.
Umfanekiso we umntu ngengqondo kwesi sigqibo esingazange sibonwe ngumatshini we-Iseult MRI uya kwenza baphandi ukutyhila iinkcukacha ezintsha zesakhiwo kunye nokusebenza kwe umntu ngengqondo enokuthi ikhanyise indlela ubuchopho obufaka ngayo imiboniso yengqondo okanye zeziphi iisignisha ze-neuronal zolwazi. Izinto ezintsha ezifunyenweyo zinokunceda ekuxilongeni nasekunyangeni iziphazamiso ze-neurodeergenerative ezifana ne-Alzheimer's kunye ne-Parkinson. Lo matshini unokunceda ekubhaqweni kweentlobo zeekhemikhali ezibandakanyekayo kwimetabolism yobuchopho engenako ukubonwa ngoomatshini be-MRI bokuqina kwemagnethi esezantsi.
Le scanner ye-11.7 ye-Tesla MRI yeprojekthi ye-Iseult iyona nto inamandla kwihlabathi umntu umatshini we-MRI womzimba wonke kwaye ufakwe kwi-NeuroSpin kwi-CEA-Paris-Saclay. Yayinike imifanekiso yokuqala ngo-2021 xa ihlola ithanga kwaye yanika imifanekiso enesisombululo se-400 microns kwimilinganiselo emithathu eqinisekisa inkqubo.
In umntu Iinkqubo ze-MRI, amandla amagnetic field okanye ngaphezulu kwe-7 Tesla ibizwa ngokuba yi-Ultra-High Fields (UHF). I-7 Tesla MRI scanners yavunywa kwi-2017 yengqondo kunye nemifanekiso encinci ye-joint. Kukho ngaphezu kwekhulu 7 koomatshini be-MRI abasebenzayo kwihlabathi jikelele. Ngaphambi kokuphumelela okutsha nje kwe-11.7 Tesla MRI scanner ye-Iseult Project, i-10.5 Tesla MRI kwiYunivesithi yaseMinnesota yayiyeyona nto iphezulu yomshini we-MRI ekusebenzeni okuvelisa kwimifanekiso ye-vivo.
Iprojekthi ye-French-German Iseult Project yokwakha i-11.7 Tesla MRI scanner yasungulwa yi-French Alternative Energies and Atomic Energy Commission (CEA) kwi-2000s. Injongo yayikukuphuhlisa 'umntu umhloli wengqondo'. Le projekthi yadibanisa amahlakani emizi-mveliso kunye nezemfundo kunye kwaye ithathe amashumi amabini eminyaka ukuba ifezekiswe. Yiteknoloji emangalisayo kwaye iza kuguqula uphando lobuchopho.
Ukuqhubela phambili, inethiwekhi yaseJamani ye-Ultrahigh Field Imaging (GUFI) isebenzela ukuseka i-14 Tesla umzimba wonke. umntu Inkqubo ye-MRI njengomthombo wophando wesizwe eJamani.
