Akatswiri amati kujambula zithunzi zachikhalidwe zachipatala, zomwe zimagwiritsidwa ntchito pozindikira, kuyang'anira kapena kuchiza matenda ena, kwakhala kovuta kwa nthawi yayitali kupeza zithunzi zomveka bwino za odwala akuda.
Ofufuza alengeza kuti apeza njira yowongolera kujambula zithunzi zachipatala, zomwe zimathandiza madokotala kuwona mkati mwa thupi, mosasamala kanthu za mtundu wa khungu.
Zomwe zapezeka posachedwapa zatulutsidwa mu magazini ya Photoacoustics ya Okutobala. Gulu la ofufuza linayesa manja a anthu 18 odzipereka, kuphatikizapo anthu omwe ali ndi khungu losiyana. Zomwe adapeza zinawonetsa mgwirizano pakati pa kuchuluka kwa zinthu zosafunikira, kusokonekera kwa chizindikiro cha photoacoustic chomwe chimakhudza kumveka bwino kwa zithunzi, ndi mdima wa khungu.
"Khungu kwenikweni limagwira ntchito ngati chotumizira mawu, koma silitumiza mtundu womwewo wa mawu olunjika omwe amapezeka mu ultrasound. M'malo mwake, mawuwo amafalikira ndipo amachititsa chisokonezo chachikulu," adatero Bell. "Chifukwa chake, kufalikira kwa mawu chifukwa cha kuyamwa kwa melanin kumakhala kovuta kwambiri pamene kuchuluka kwa melanin kumawonjezeka."
Kusintha njira
Kafukufukuyu, wochitidwa mogwirizana ndi ofufuza aku Brazil omwe adakumanapo kale ndi imodzi mwa ma algorithm a Bell, adavumbulutsa kuti chiŵerengero cha chizindikiro-ku-phokoso, chomwe ndi muyeso wasayansi woyerekeza mphamvu ya chizindikiro ndi phokoso lakumbuyo, chidakulitsidwa pamitundu yonse ya khungu pamene ofufuzawo adagwiritsa ntchito njira yotchedwa "short-lag spatial coherence beamforming" panthawi yojambula zithunzi zachipatala. Njirayi, yomwe poyamba idapangidwira kujambula zithunzi za ultrasound, ikhoza kusinthidwa kuti igwiritsidwe ntchito pojambula zithunzi za photoacoustic.
Njirayi imagwiritsa ntchito ukadaulo wa kuwala ndi ultrasound kuti ipange njira yatsopano yojambulira zithunzi zachipatala, monga momwe Theo Pavan, yemwe amagwira ntchito ku dipatimenti ya fizikisi ku Yunivesite ya São Paulo ku Brazil adafotokozera. Malinga ndi Pavan, kafukufuku wawo adatsimikiza kuti njira yatsopanoyi siyikhudzidwa kwambiri ndi mtundu wa khungu, zomwe zimapangitsa kuti chithunzi chikhale chapamwamba poyerekeza ndi njira zachikhalidwe zomwe zimagwiritsidwa ntchito nthawi zambiri m'munda.
Ofufuzawo adawona kuti kafukufuku wawo ndiye woyamba kuwunika mtundu wa khungu moyenera komanso kupereka umboni wokwanira komanso wochuluka wosonyeza kuti chizindikiro cha kuwala kwa khungu komanso zinthu zina zosafunikira zimawonjezeka pamene kuchuluka kwa melanin m'maselo a khungu kumawonjezeka.
Kuganiziranso bwino za chisamaliro chaumoyo
Zomwe ofufuzawa adapeza zitha kukhala ndi tanthauzo lalikulu pakulimbikitsa chilungamo pa chisamaliro chaumoyo pamlingo waukulu. Dr. Camara Jones, dokotala wa mabanja, katswiri wa matenda, komanso purezidenti wakale wa American Public Health Association, yemwe sanachite nawo kafukufukuyu, adawonetsa kukondera mu ukadaulo wasayansi posankha zinthu zomwe zimathandiza kwambiri anthu omwe ali ndi khungu loyera. Jones adagogomezera kuti kugwiritsa ntchito mtundu ngati chinthu chowopsa pa thanzi ndi nkhani yofunika kwambiri, chifukwa ndi njira yolumikizirana ndi anthu yomwe imachokera ku kutanthauzira kwa anthu mawonekedwe akuthupi osati zinthu zamoyo. Adanenanso kuti palibe maziko a majini a mtundu wina mu genome ya munthu ngati umboni wotsimikizira izi. Kafukufuku wakale adazindikiranso kukondera kwa khungu mu ukadaulo wazachipatala, zomwe zikuwonetsa kuti zida zamankhwala zomwe zimagwiritsa ntchito infrared sensing sizingagwire ntchito bwino pakhungu lakuda chifukwa cha kusokoneza kuwala.
Bell adawonetsa chiyembekezo kuti kafukufuku wake akhoza kutsegula chitseko chothetsera tsankho pazachipatala ndikulimbikitsa ena kupanga ukadaulo womwe umapindulitsa anthu onse, mosasamala kanthu za mtundu wa khungu lawo.
"Ndikukhulupirira kuti ndi luso lowonetsa kuti tingathe kupanga ndi kupanga ukadaulo - sizigwira ntchito kwa gulu limodzi laling'ono la anthu koma zimagwiranso ntchito kwa anthu ambiri. Izi ndizolimbikitsa kwambiri osati gulu langa lokha, komanso magulu padziko lonse lapansi kuti ayambe kuganiza motere popanga ukadaulo. Kodi umathandiza anthu ambiri?" Bell adatero.

Monga tonse tikudziwira, chitukuko cha makampani opanga zithunzi zachipatala sichingasiyanitsidwe ndi chitukuko cha zida zamankhwala zingapo - majekeseni osiyanitsa ndi zinthu zina zothandizira - zomwe zimagwiritsidwa ntchito kwambiri m'munda uno. Ku China, komwe kumadziwika ndi makampani opanga zinthu, kuli opanga ambiri otchuka kunyumba ndi kunja chifukwa chopanga zida zojambula zithunzi zachipatala, kuphatikizapoLnkMedKuyambira pomwe idakhazikitsidwa, LnkMed yakhala ikuyang'ana kwambiri pa ntchito yopangira majekeseni otsutsana ndi mpweya woipa kwambiri. Gulu la mainjiniya la LnkMed limatsogozedwa ndi PhD yokhala ndi zaka zoposa khumi zokumana nazo ndipo ikuchita kafukufuku ndi chitukuko mozama. Motsogozedwa ndi iye,Injector ya mutu umodzi ya CT,Injector ya mutu wa CT iwiri,Injector ya MRI contrastndiInjector yotsutsana ndi kuthamanga kwa magazi (Angiography)Zapangidwa ndi zinthu izi: thupi lolimba komanso laling'ono, mawonekedwe osavuta komanso anzeru ogwirira ntchito, ntchito zake zonse, chitetezo champhamvu, komanso kapangidwe kolimba. Tikhozanso kupereka ma syringe ndi ma chubu omwe amagwirizana ndi mitundu yotchuka ya ma injector a CT, MRI, DSA Ndi malingaliro awo oona mtima komanso mphamvu zawo zaukadaulo, antchito onse a LnkMed akukupemphani kuti mubwere kudzafufuza misika yambiri pamodzi.
