Iseult Project's 11.7 Tesla MRI tshuab tau coj cov duab anatomical zoo kawg li ntawm lub neej tib neeg hlwb los ntawm cov neeg koom. Nov yog thawj qhov kev kawm nyob tib neeg lub hlwb los ntawm lub tshuab MRI ntawm lub zog sib nqus zoo li no uas tau ua tiav cov duab ntawm 0.2 hli hauv-dav hlau daws teeb meem thiab 1 hli hlais thickness (sawv cev rau lub ntim sib npaug ntawm ob peb txhiab neurons) hauv lub sijhawm luv luv ntawm tsuas yog 4 feeb.
Cov duab ntawm tib neeg lub hlwb ntawm qhov kev daws teeb meem tsis tau pom dua los ntawm Iseult MRI tshuab yuav pab tau soj ntsuam ntawm los nthuav tawm cov qauv tshiab thiab cov ntsiab lus ua haujlwm ntawm tib neeg lub hlwb uas tej zaum yuav ua rau lub teeb pom kev zoo li cas lub hlwb encodes lub hlwb sawv cev los yog dab tsi yog neuronal kos npe ntawm kev nco qab. Cov kev tshawb pom tshiab tuaj yeem pab kuaj mob thiab kho cov kab mob neurodegenerative xws li Alzheimer's thiab Parkinson's. Lub tshuab no tseem tuaj yeem pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau cov tshuaj chotabism uas tsis tuaj yeem pom los ntawm MRI MACHINE ntawm qhov qis dua sib nqus teb lub zog.
Qhov 11.7 Tesla MRI scanner ntawm Iseult project yog lub ntiaj teb muaj zog tshaj plaws tib neeg tag nrho lub cev MRI tshuab thiab tau teeb tsa ntawm NeuroSpin ntawm CEA-Paris-Saclay. Nws tau xa thawj cov duab hauv xyoo 2021 thaum nws tau tshuaj xyuas lub taub taub thiab muab cov duab nrog kev daws teeb meem ntawm 400 microns hauv peb qhov ntev uas tau lees paub cov txheej txheem.
In tib neeg MRI systems, magnetic teb muaj zog ntawm lossis siab dua 7 Tesla yog hu ua Ultra-High Fields (UHF). 7 Tesla MRI scanners tau pom zoo hauv 2017 rau lub hlwb thiab cov duab me me. Muaj ntau tshaj ib puas 7 T MRI tshuab ua haujlwm thoob ntiaj teb. Ua ntej ua tiav tsis ntev los no ntawm 11.7 Tesla MRI scanner ntawm Iseult Project, 10.5 Tesla MRI ntawm University of Minnesota yog lub zog siab tshaj plaws MRI tshuab hauv kev ua haujlwm tsim tawm hauv vivo cov duab.
Fab Kis-German Iseult Project rau kev tsim lub 11.7 Tesla MRI scanner tau tsim los ntawm Fab Kis Kev Siv Hluav Taws Xob thiab Atomic Energy Commission (CEA) hauv xyoo 2000s. Lub hom phiaj yog los tsim ib qho 'tib neeg hlwb explorer'. Txoj haujlwm no coj cov kev lag luam thiab kev kawm sib koom ua ke thiab tau siv sijhawm ob xyoos los ua kom muaj txiaj ntsig. Nws yog ib qho txuj ci txuj ci tseem ceeb thiab yuav hloov pauv kev tshawb fawb lub hlwb.
Kev nce qib, German Ultrahigh Field Imaging (GUFI) network tab tom ua haujlwm los tsim kom muaj 14 Tesla tag nrho lub cev tib neeg MRI system raws li kev tshawb fawb thoob ntiaj teb hauv lub teb chaws Yelemees.
