Luntha lochita kupanga pozindikira kuopsa kwa shuga

Gulu la ochita kafukufuku linagwiritsa ntchito luso lapamwamba, lopanda mphamvu kuti lipeze zithunzi za mitsempha yaing'ono yamagazi yomwe imapezeka pansi pa khungu la odwala matenda a shuga, ndipo amagwiritsa ntchito algorithm ya intelligence intelligence kuti apange "mapu" omwe angagwiritsidwe ntchito kuti adziwe kuopsa kwa matenda a shuga. matenda. Tekinolojeyi ikangotha ​​kunyamula, imatha kugwiritsidwa ntchito kuyang'anira momwe chithandizo chimagwirira ntchito, malinga ndi New Atlas, potchula magazini ya Nature Biomedical Engineering.

Microangiopathy

Microangiopathy, yomwe makoma a ma capillaries amagazi amakhala okhuthala komanso ofooka kotero kuti amakhetsa magazi, kutulutsa mapuloteni, komanso kuthamanga kwa magazi pang'onopang'ono ndi vuto lalikulu la matenda a shuga, omwe amatha kukhudza ziwalo zambiri za thupi, kuphatikiza khungu.

Ofufuza ochokera ku Technical University of Munich apanga TUM, njira yopezera zithunzi zambiri za mitsempha yamagazi pansi pa khungu la odwala matenda a shuga pogwiritsa ntchito luntha lochita kupanga kuti adziwe kuchuluka kwa vutoli.

Kujambula kwa audio-visual

Kujambula kwa Optoacoustic kumagwiritsa ntchito mafunde a kuwala kuti apange mafunde a ultrasound mkati mwa minofu. Kukula kwakung'ono ndi kutsika kwa minofu yozungulira mamolekyu, yomwe imayamwa kwambiri kuwala, imapanga zizindikiro zomwe zimalembedwa ndi masensa ndikusinthidwa kukhala zithunzi zowoneka bwino. Mapuloteni onyamula okosijeni a hemoglobin ndi amodzi mwa mamolekyuwa omwe amamwa kuwala, ndipo popeza amakhazikika m'mitsempha yamagazi, kujambula kwa optoacousic kumapanga zithunzi zatsatanetsatane za mitsempha yamagazi yomwe njira zina zosapanga opaleshoni sizingapange, kuphatikiza pakuchita mwachangu komanso kuchita. osagwiritsa ntchito ma radiation.

Kuzama komanso tsatanetsatane

Pakafukufuku watsopano, ochita kafukufuku adapanga njira yeniyeni yojambula zithunzi yotchedwa RSOM, yomwe imatha kupeza deta pakuya kosiyana kwa khungu nthawi imodzi mpaka kuya kwa 1 millimeter, zomwe Angelos Karlas, wofufuza wamkulu wa phunzirolo, adanena. "Kuzama komanso tsatanetsatane kuposa njira zina zowonera."

ukadaulo wa RSO

Ofufuzawa adagwiritsa ntchito ukadaulo wa RSOM kujambula zithunzi zapakhungu pamiyendo ya odwala 75 omwe ali ndi matenda ashuga komanso gulu lolamulira la anthu 40 ndipo adagwiritsa ntchito algorithm yanzeru yopangira kuzindikira zomwe zimagwirizana ndi zovuta za matenda ashuga. Ofufuzawa adapanga mndandanda wa 32 zosintha zofunika kwambiri pakhungu la microvasculature, kuphatikiza kukula kwa mitsempha yamagazi ndi kuchuluka kwa nthambi zomwe ali nazo.

Chiwerengero cha mitsempha ya magazi

Ofufuzawo adanena kuti chiwerengero cha ziwiya ndi nthambi zomwe zili pakhungu zimachepa kwa odwala matenda a shuga, koma zimawonjezeka mu epidermis yomwe ili pafupi kwambiri ndi khungu. Makhalidwe onse a 32 omwe adadziwika ndi ochita kafukufukuwo adakhudzidwa ndi kukula kwa matenda ndi kuopsa kwake. Polemba zizindikiro za 32, gulu lofufuza linawerengera "microangiopathy score," yomwe imagwirizanitsa mitsempha yaing'ono yamagazi pakhungu ndi kuopsa kwa matenda a shuga.

Pamtengo wotsika komanso mkati mwa mphindi zochepa

Vassilis Ntziachristos, wofufuza pa kafukufukuyu, adanena kuti pogwiritsa ntchito "teknoloji ya RSOM ndizotheka kufotokoza mozama zotsatira za matenda a shuga," akufotokoza kuti "ndi mphamvu zomwe zikubwera kuti RSOM ikhale yotheka komanso yotsika mtengo, zotsatirazi zidzatsegula njira yatsopano. kupitiriza kuyang’anira mkhalidwe wa anthu okhudzidwawo—anthu oposa 400 miliyoni.” Anthu padziko lonse lapansi. M’tsogolomu, poyezetsa mwamsanga ndiponso mosapweteka, zingatenge mphindi zochepa chabe kuti mudziwe ngati chithandizo chili ndi zotsatirapo zake, ngakhale wodwalayo ali kunyumba.
