Ubuhlakani bokwenziwa ekuxilongeni ubunzima besifo sikashukela

Ithimba labacwaningi lasebenzisa ubuchwepheshe obunokulungiswa okuphezulu, okungahlanyisi ukuthola izithombe zemithambo yegazi emincane etholakala ngaphansi kwesikhumba seziguli ezinesifo sikashukela, futhi lasebenzisa i-algorithm yobuhlakani bokwenziwa ukuze lenze “amaphuzu” angasetshenziswa ukunquma ukuqina kwesifo sikashukela. isifo. Uma lobu buchwepheshe sebuphathekayo, bungasetshenziswa ukuqapha ukusebenza ngempumelelo kokwelashwa, ngokusho kwe-New Atlas, ecaphuna iphephabhuku i-Nature Biomedical Engineering.

I-Microangiopathy

I-Microangiopathy, lapho izindonga zamangqamuzana egazi ziba namandla kakhulu futhi zibe buthakathaka kangangokuthi zopha, amaprotheni avuzayo, nokuhamba kancane kwegazi kuyinkimbinkimbi enkulu yesifo sikashukela, esingathinta izitho eziningi zomzimba, kuhlanganise nesikhumba.

Abacwaningi abavela e-Technical University yaseMunich benze i-TUM, indlela yokuthola izithombe ezinemininingwane yemithambo yegazi ngaphansi kwesikhumba seziguli ezinesifo sikashukela besebenzisa ubuhlakani bokwenziwa ukuze kutholwe inani lobunzima besimo.

Isithombe somsindo nokubukwayo

I-Optoacoustic imaging isebenzisa ama-pulses okukhanya ukukhiqiza amaza e-ultrasound ngaphakathi kwezicubu. Ukwandiswa nokufinyela okuncane esicutshini ezungeze ama-molecule, abamba ukukhanya ngokuqinile, kudala amasignali arekhodwa izinzwa futhi aguqulelwe abe izithombe zokucaca okuphezulu. Iprotheyini ethwala umoya-mpilo i-hemoglobin ingenye yala ma-molecule abamba ukukhanya, futhi njengoba igxile emithanjeni yegazi, i-optoacousic imaging ikhiqiza izithombe ezinemininingwane yemithambo yegazi ezinye izindlela ezingahlinzeki ezingakwazi ukukhiqiza, ngaphezu kokuba inqubo esheshayo futhi iyakwenza. ungasebenzisi imisebe.

Ukujula okwengeziwe nemininingwane

Ocwaningweni olusha, abacwaningi bathuthukise indlela ethile yokucabanga ye-optical-acoustic ebizwa ngokuthi i-RSOM, engathola idatha ekujuleni okuhlukene kwesikhumba ngesikhathi esisodwa kuze kufike ekujuleni kwemilimitha engu-1, ashiwo u-Angelos Karlas, umcwaningi oholayo wocwaningo. "Ukujula okwengeziwe kanye nemininingwane kunezinye izindlela zokubona."

Ubuchwepheshe be-RSOM

Abacwaningi basebenzise ubuchwepheshe be-RSOM ukuthatha izithombe zesikhumba emilenzeni yeziguli ezingama-75 ezinesifo sikashukela kanye neqembu elilawulayo labantu abangama-40 futhi basebenzise i-algorithm yobuhlakani bokwenziwa ukukhomba izici ezifanele emtholampilo ezihlobene nezinkinga zesifo sikashukela. Abacwaningi benza uhlu lwezinguquko ezingu-32 ezibalulekile ikakhulukazi ku-microvasculature yesikhumba, okuhlanganisa ububanzi bemithambo yegazi kanye nenani lamagatsha abanalo.

Inani lemithambo yegazi

Abacwaningi baqaphele ukuthi inani lemikhumbi namagatsha ongqimba lwesikhumba liyancipha ezigulini ezinesifo sikashukela, kodwa ukwanda kwe-epidermis eseduze nendawo yesikhumba. Zonke izici ze-32 ezikhonjwe abacwaningi zathintwa ukuqhubekela phambili kwesifo nokuqina. Ngokuhlanganisa izici ze-32, ithimba labacwaningi libale "isikolo se-microangiopathy," esixhumanisa isimo semithambo emincane yegazi esikhumbeni kanye nobunzima besifo sikashukela.

Ngezindleko eziphansi futhi phakathi nemizuzu embalwa

UVassilis Ntziachristos, umcwaningi ocwaningweni, uthe ngokusebenzisa “ubuchwepheshe be-RSOM kungenzeka ukuchaza ngokwezibalo imiphumela yesifo sikashukela,” echaza ukuthi “ngekhono elivelayo lokwenza i-RSOM iphatheke kalula futhi ingabizi, le miphumela izovula indlela entsha. ukuqapha njalo isimo salabo abathintekile - abantu abangaphezu kwezigidi ezingu-400.” Abantu emhlabeni wonke. Ngokuzayo, ngokuhlolwa okusheshayo nokungenabuhlungu, kuzothatha imizuzu embalwa kuphela ukunquma ukuthi ingabe ukwelashwa kunomthelela, ngisho noma isiguli sisekhaya.
