Abasebenzi belebhu ye-physics yezamayeza eParis (e-Espci Paris-Psl, i-Inserm, i-CNRS) yenze umlinganiso ongazange wenziwe ngaphambili, oxeliweyo kwisifundo sephephandaba i-Biodyer. Oku kwenzeke ngenxa ye-microscopy yendawo ye-Ultrasonic yesisombululo se-Ultra, kunye ne-sonography esezantsi kunye nokusetyenziswa kweearhente zokwahlula.
Imithambo yegazi yengqondo yinethiwekhi enzima ebonelela ngee-neurons ngeoksijini kunye nezondlo. Ilandela koku ukuba umsebenzi we-vascular no-neranial unxulumene ngokusondeleyo, kwaye ukuphazamiseka kwiinqanawa kuthathwa njengeyona nto iphambili kwiziphazamiso zemfundo ezininzi. Ukuxilongwa kunye nokunyangwa kwezi zifo zintsonkothiswa kukungabikho kolwazi malunga nemisebenzi yemithambo yegazi kunye nezithintelo ekuboneni ububoni beCerebrovacular.
I-computer i-angiography ye-angiography kunye ne-agnetic donagraphy zezona ndlela zimbini ziqhelekileyo zokufumana umfanekiso wezitya zegazi. Bagubungela ubugcisa obukhulu obufikelela ubukhulu beemitha ezimbalwa, kodwa akunakufumana iintloko ezincinci. Ukongeza, i-angiografi ayiboneleli ngolwazi olunamandla malunga nenethiwekhi ye-vascular kwizikali ezahlukeneyo zendawo.
Isigqibo esicetyiswe ngababhali besi sifundo esitsha kufuneka sizalise lo msantsa, kuba sinika imifanekiso eguqukayo yemijelo yegazi yonke inethiwekhi ye-vascular ivela kwii-capillaries ezincinci. Ukongeza, le teknoloji ayisiyonto ingenamhlaseli, engahlaseli, elula kwaye ayizukufuna utyalomali olunzima lwezezimali.
Iqela le-mikael lifake iqela le-Ultra-ikhawulezileyo le-Ultra-ikhawulezileyo-Isifundo esingahlaseli somzimba sisebenzisa amaza e-Ultrasound, evumela amawaka emifanekiso nganye. Emva koko thelekisa izinto zaya kushukuma: Ngenxa yoko, i-micropulaulings evela kwigesi ye-biompative, ilawulwa ngokuzenzekelayo, ijikelezwe kuyo yonke i-vascular yothungelwano lwengqondo. Babe babonwa yindlela ye-probe ye-ultrasound, ebekwe ecaleni kwentloko yesigulana, etempileni. Ngokumisela isikhundla sezigidi zeentsholongwane kwimizuzwana embalwa, izazinzulu zazikwazi ukubuyisela i-anatomy yenethiwekhi ye-vascular ukuya kwisikali ezingama-25, ngelixa siqokelela ulwazi malunga nezinto ezinamandla zegazi.
Indlela yayelwe kwizilwanyana ezincinci zelebhu ngo-2015, kodwa ukwenza imifanekiso yengqondo yabantu abadala akuphumelelanga. Ingxaki yayikukuba, ekuqaleni, umqondiso we-ultrasonic ugqwetha xa udlula kwikhaka, ekhokelela ekuwohlokeni komgangatho womfanekiso. Okwesibini, kwakuyimfuneko ukukhulisa i-Algorithms yokulungisa i-Algorithms, kuba nayiphi na intshukumo encinci kwingqondo ithintela ukuba kunokwenzeka ukuba i-miron ichanekile i-micron.
"Eli" Premiere yeHlabathi "ebantwini lalinokwenzeka ngenxa yokuphunyezwa kweendlela ezininzi. Eyokuqala yimbono yokuqala, ebonelela ngesixa esikhulu sedatha ixesha elifutshane kakhulu kwaye likuvumela ukuba uhlukane phakathi kwe-ACoustic Kutyikitywe phakathi kwe-microfuupuction nganye. Emva koko indawo ye-Ultrasound ithathe umda wemvume xa umfanekiso wento encinci yindawo efihlakeleyo yebala-ngaphezulu kwento yokwenyani. Kodwa ukuba le nto iguqulelwe, inokuba sengqiqweni ukucinga ukuba indawo eyahlukileyo yindawo yalo imbindi yebala elibekiweyo. Kwimeko yethu, ii-microbhubhu ezijikelezayo kwigazi idlala indima yezinto eziqhoshwe kwaye ikuvumela ukuba ubuyisele indawo ngqo yenqanawa nganye yegazi. Okokugqibela, ukubhaliswa kwee Microbbbles kunikezelwa ukufikelela kwi-wave ekhupha into engekho mthethweni micron, kwaye, ke, kuyo ivunyelwe ukubuyisela izinto eziphazamisayo kwi-javes ukuba ilungisa izinto ezivelayo, "utshilo uCharlie Demené, a Umbhali okhokelayo wesifundo.
Ngenxa yophuhliso lwayo, izazinzulu sele zikwazile ukulungisa iinkcukacha ezincinci zegazi elihamba ngegazi kwindawo ye-Aneurysm ephakathi embindini wesigulana esinye sezigulana. Amathuba amatsha okubanjwa kweenqanawa kuvula indlela yokuqonda kunye nokuqonda isifo se-cerebescular, njengokubetha, kunye nezifo ze-neurodegenegenelity.
Ukongeza kubo bonke, kufanelekile ukuba i-microscopy yendawo yase-Uptrasonic ilula ukusebenzisa iKecachians xa ithelekiswa neendlela ezikhoyo, ingeniso ngakumbi kwaye incinci kakhulu - inkqubo inokwenziwa kufutshane nebhedi yesigulana.
