Ubukrelekrele bokwenziwa ekuxilongeni ubunzima besifo seswekile

Iqela labaphandi lisebenzise itekhnoloji ephezulu, engenakuchaphazeleka ukufumana imifanekiso yemithambo yegazi emincinci efunyenwe phantsi kwesikhumba sezigulane ezineswekile, kwaye yasebenzisa i-algorithm yobukrelekrele bokwenziwa ukwenza "amanqaku" anokuthi asetyenziswe ukumisela ubungqongqo besifo seswekile. isifo. Nje ukuba le teknoloji iphathekayo, ingasetyenziselwa ukubeka esweni ukusebenza konyango, ngokutsho kweAtlas eNtsha, ecaphula iphephancwadi iNature Biomedical Engineering.

I-Microangiopathy

I-Microangiopathy, apho iindonga ze-capillaries zegazi ziba ngqingqwa kwaye zibuthathaka kangangokuba zopha, iprotheni evuzayo, kunye nokucotha kwegazi yingxaki enkulu yesifo seswekile, enokuthi ichaphazele amalungu amaninzi emzimbeni, kubandakanya ulusu.

Abaphandi abavela kwiYunivesithi yaseMunich yezobuchwepheshe baye baphuhlisa i-TUM, indlela yokufumana imifanekiso ecacileyo yemithambo yegazi phantsi kwesikhumba sezigulane zesifo seswekile zisebenzisa i-intelligence ye-artificial ukufumanisa ubukhulu bemeko.

Umfanekiso we-audio-visual

I-Optoacoustic imaging isebenzisa ii-pulses zokukhanya ukuvelisa amaza e-ultrasound ngaphakathi kwezicubu. Ukwandiswa okuncinci kunye nokunyanzeliswa kwezicubu ezijikeleze iamolekyu, ezifunxa ngamandla ukukhanya, zidala imiqondiso erekhodwa zinzwa kwaye iguqulelwe kwimifanekiso ephezulu. Iprotheyini ethwala ioksijini ihemoglobin yenye yezi molekyuli ezifunxa ukukhanya, kwaye njengoko igxile kwimithambo yegazi, i-optoacoustic imaging ivelisa imifanekiso ecacileyo yemithambo yegazi engenakuveliswa zezinye iindlela ezingezizo utyando, ukongeza kwinkqubo ekhawulezayo kwaye iyayenza. ungasebenzisi imitha.

Ubunzulu obungakumbi kunye neenkcukacha

Kuphononongo olutsha, abaphandi bavelisa indlela yokucinga ye-optical-acoustic ebizwa ngokuba yi-RSOM, enokufumana idatha kubunzulu obuhlukeneyo bolusu ngaxeshanye ukuya kubunzulu be-1 millimeter, wathi u-Angelos Karlas, umphandi okhokelayo wophando. "Ubunzulu kunye neenkcukacha ngakumbi kunezinye iindlela zamehlo."

Iteknoloji yeRSOM

Abaphandi basebenzise iteknoloji ye-RSOM ukuthatha imifanekiso yesikhumba kwimilenze yezigulane ze-75 zesifo sikashukela kunye neqela elilawulayo labantu abangama-40 kwaye basebenzise i-algorithm yobukrelekrele bokwenza ukuchonga iimpawu ezifanelekileyo zeklinikhi ezinxulumene neengxaki zesifo sikashukela. Abaphandi benza uluhlu lwe-32 utshintsho olubaluleke kakhulu kwi-microvasculature yolusu, kubandakanywa nobubanzi bemithambo yegazi kunye nenani lamasebe abanalo.

Inani lemithambo yegazi

Abaphandi baqaphele ukuba inani leenqanawa kunye namagatsha esikhumbeni sesikhumba siyancipha kwizigulane zesifo sikashukela, kodwa ukwanda kwi-epidermis ekufutshane nesikhumba. Zonke iimpawu ze-32 ezichongiweyo ngabaphandi zachatshazelwa kukukhula kwesifo kunye nobunzima. Ngokuqulunqa iimpawu ze-32, iqela lophando labala "inqaku le-microangiopathy," elidibanisa imeko yemithanjana encinci yegazi esikhumbeni kunye nobunzima besifo sikashukela.

Ngeendleko eziphantsi kunye nemizuzu embalwa

UVassilis Ntziachristos, umphandi kwisifundo, wathi ukusebenzisa "i-RSOM iteknoloji inokwenzeka ukuchaza ngokomlinganiselo imiphumo yesifo seswekile," echaza ukuba "kunye namandla avelayo okwenza i-RSOM ephathekayo kwaye ingabizi, ezi ziphumo ziya kuvula indlela entsha. ukubek’ esweni ngokuqhubekayo imeko yabo bachaphazelekileyo—abantu abangaphezu kwezigidi ezingama-400.” Abantu ehlabathini lonke. Kwixesha elizayo, ngovavanyo olukhawulezayo nolungenazintlungu, kuyakuthatha imizuzu embalwa kuphela ukufumanisa ukuba ingaba unyango lunesiphumo na, nangona isigulana sisekhaya.
