Iseult Project's 11.7 Tesla MRI muchina watora zvinoshamisa anatomical mifananidzo yehupenyu. munhu uropi kubva kuvatori vechikamu. Ichi chidzidzo chekutanga chekurarama munhu ubongo nemuchina weMRI wesimba remagineti rakakura kudaro rakapa mifananidzo ye 0.2 mm mu-ndege resolution uye 1 mm slice ukobvu (inomiririra vhoriyamu yakaenzana nezviuru zvishoma neuroni) munguva pfupi yekutora yemaminetsi mana chete.
Mufananidzo we munhu ubongo pachisarudzo ichi chisina kumboitika nemuchina weIseult MRI uchagonesa vatsvakurudzi kuburitsa zvitsva zvezvimiro uye zvinoshanda zve munhu ubongo iyo inogona kujekesa kuti uropi hunoisa sei zvinomiririra pfungwa kana kuti chii chinonzi neuronal siginecha yekuziva. Zvitsva zvakawanikwa zvinogona kubatsira mukuongororwa uye kurapwa kweaurodegenerative kusagadzikana senge Alzheimer's uye Parkinson's. Muchina uyu unogona zvakare kubatsira mukuona kwemakemikari emhando anosanganisirwa muuropi metabolism ayo asingagone kuonekwa neimwe nzira nemichina yeMRI yeakadzika magineti simba.
Iyi 11.7 Tesla MRI scanner yeIseult project ndiyo ine simba guru pasi rose munhu muviri wose weMRI muchina uye unoiswa paNeuroSpin paCEA-Paris-Saclay. Yakanga yaunza mifananidzo yekutanga muna 2021 payakaongorora nhanga ikapa mifananidzo ine resolution ye400 microns muzvikamu zvitatu zvakasimbisa maitiro.
In munhu MRI masisitimu, simba remagineti pa7 kana pamusoro pe7 Tesla inonzi Ultra-High Fields (UHF). 2017 Tesla MRI scanners yakabvumidzwa mu7 yehuropi uye madiki majoini ekufungidzira. Kune anopfuura zana 11.7 T MRI michina iri kushanda pasi rese. Isati yabudirira ichangoburwa ye10.5 Tesla MRI scanner yeIseult Project, XNUMX Tesla MRI paYunivhesiti yeMinnesota ndiyo yaive yakanyanya simba MRI muchina mukushanda uchigadzira mu vivo mifananidzo.
Iyo French-German Iseult Project yekuvaka 11.7 Tesla MRI scanner yakatangwa neFrench Alternative Energies uye Atomic Energy Commission (CEA) mu2000s. Chinangwa chaive chekugadzira 'munhu brain explorer'. Chirongwa ichi chakaunza vadyidzani vemaindasitiri nevedzidzo pamwechete uye chatora makumi maviri emakore kuti chizadzike. Chishamiso chetekinoroji uye chichashandura tsvagiridzo yehuropi.
Kufambira mberi, iyo yeGerman Ultrahigh Field Imaging (GUFI) network iri kushanda kumisa gumi nemana Tesla muviri wese. munhu MRI system senyika yekutsvagisa sosi muGermany.
