Njira Yosavuta Yomwe Ofufuza Amapangira Kujambula Zachipatala Kuwerenga Khungu Lakuda

Kujambula kwachikhalidwe, komwe kumagwiritsidwa ntchito pozindikira, kuyang'anira kapena kuchiza matenda ena, kwakhala kuvutikira kwanthawi yayitali kuti apeze zithunzi zowonekera bwino za odwala akhungu lakuda, akatswiri akutero.

Ofufuza alengeza kuti apeza njira yosinthira zithunzi zachipatala, zomwe zimalola madokotala kuyang'ana mkati mwa thupi, mosasamala kanthu za mtundu wa khungu.

Zomwe zapezedwa posachedwa zidatulutsidwa m'magazini ya Okutobala ya Photoacoustics. Gulu la ofufuza lidayesa pamiyendo ya anthu odzipereka 18, kuphatikiza anthu omwe ali ndi khungu losiyanasiyana. Zomwe adapeza zidawulula kulumikizana pakati pa kuchuluka kwa zinthu, kupotoza kwa chizindikiro cha photoacoustic chomwe chimakhudza kuwonekera kwa zithunzi, ndi mdima wa khungu.

“Khungu limagwira ntchito ngati chopatsira mawu, koma silimatumiza mawu amtundu womwewo omwe amapezeka mu ultrasound. M'malo mwake, phokoso limafalikira ponseponse ndipo limayambitsa chisokonezo chachikulu," adatero Bell. "Chotsatira chake, kufalikira kwa phokoso chifukwa cha kuyamwa kwa melanin kumakhala kovuta kwambiri pamene chigawo cha melanin chikukwera."

Kusintha njira

Kafukufukuyu, wopangidwa mogwirizana ndi ofufuza aku Brazil omwe adakumanapo ndi chimodzi mwazomwe adachita ndi Bell, adawulula kuti chiŵerengero cha signal-to-noise, metric yasayansi yoyerekeza mphamvu ya chizindikiro ndi phokoso lakumbuyo, idalimbikitsidwa pakhungu lonse pamene ofufuzawo adalemba ntchito. njira yotchedwa "short-lag spatial coherence beamforming" panthawi yojambula zamankhwala. Njira imeneyi, yomwe poyamba inapangidwira kujambula kwa ultrasound, imatha kusinthidwa kuti igwiritsidwe ntchito pazithunzi za photoacoustic.

Njirayi imaphatikizapo teknoloji ya kuwala ndi ultrasound kuti apange njira yatsopano yowonetsera zachipatala, monga momwe anafotokozera Theo Pavan, yemwe amagwirizana ndi dipatimenti ya physics ku yunivesite ya São Paulo ku Brazil. Malinga ndi Pavan, kafukufuku wawo adatsimikizira kuti njira yatsopanoyi imakhudzidwa kwambiri ndi mtundu wa khungu, zomwe zimapangitsa kuti chithunzithunzi chikhale chapamwamba poyerekeza ndi njira zomwe zimagwiritsidwa ntchito nthawi zambiri m'munda.

Ofufuzawo adawona kuti kafukufuku wawo ndi woyamba kuti awonetsetse kawonekedwe ka khungu komanso kupereka umboni wokwanira komanso wochulukira wowonetsa kuti mawonekedwe amtundu wa photoacoustic pakhungu ndi zinthu zopanda pake zimachulukitsidwa pamene epidermal melanin ikuwonjezeka.

Kuganiziranso mozama pazaumoyo

Zomwe ofufuzawa apeza zitha kukhala ndi tanthauzo lalikulu pakulimbikitsa chilungamo pazaumoyo pamlingo waukulu.Dr. Camara Jones, dokotala wa mabanja, katswiri wa miliri, komanso pulezidenti wakale wa American Public Health Association, yemwe sanachite nawo kafukufukuyu, anatsindika kukondera kwa sayansi ya sayansi pokomera mankhwala omwe ali othandiza kwambiri kwa anthu omwe ali ndi khungu lopepuka. Jones anatsindika kuti kugwiritsa ntchito mtundu ngati chiwopsezo cha thanzi ndi nkhani yofunika kwambiri, chifukwa ndi chikhalidwe cha anthu chozikidwa pa momwe anthu amatanthauzira maonekedwe a thupi osati zinthu zachilengedwe. Iye adanenanso za kusakhalapo kwa chibadwa cha mitundu yosiyanasiyana mumtundu wa anthu monga umboni wotsimikizira izi. pakhungu lakuda chifukwa cha kusokoneza komwe kungathe kunyezimira.

Bell adawonetsa kuti akukhulupirira kuti kafukufuku wake atha kutsegulira khomo lakuthetsa tsankho pazachipatala ndikulimbikitsa ena kupanga ukadaulo womwe umapindulitsa anthu onse, mosasamala kanthu za mtundu wa khungu lawo.

"Ndikukhulupirira kuti ndi kuthekera kowonetsa kuti titha kupanga ndi kupanga ukadaulo - izi sizimagwira ntchito pagulu laling'ono la anthu koma zimagwiranso ntchito kwa anthu ambiri. Izi ndizolimbikitsa kwambiri osati gulu langa lokha, koma kuti magulu padziko lonse lapansi ayambe kuganiza motere popanga teknoloji. Kodi imathandiza anthu ambiri?" Bell anatero.

Monga tonse tikudziwira, chitukuko cha makampani opanga zithunzi zachipatala sichingasiyanitsidwe ndi chitukuko cha zida zachipatala - majekeseni osiyanitsa ndi mankhwala omwe amawathandiza - omwe amagwiritsidwa ntchito kwambiri pa ntchitoyi. Ku China, komwe kumadziwika chifukwa chamakampani opanga zinthu, pali opanga ambiri otchuka kunyumba ndi kunja chifukwa chopanga zida zofananira zamankhwala, kuphatikizaLnkMed. Chiyambireni kukhazikitsidwa kwake, LnkMed yakhala ikuyang'ana kwambiri pa majekeseni ophatikizika kwambiri. Gulu la engineering la LnkMed limatsogozedwa ndi Ph.D. ali ndi zaka zopitilira khumi ndipo ali wotanganidwa kwambiri ndi kafukufuku ndi chitukuko. Motsogozedwa ndi iye, aCT single head injector,CT double mutu jekeseni,Injector yofananira ya MRI,ndiAngiography high-pressure jekeseni wothandizirazidapangidwa ndi izi: thupi lolimba komanso lolumikizana, mawonekedwe osavuta komanso anzeru ogwirira ntchito, ntchito zonse, chitetezo chokwanira, komanso kapangidwe kolimba. Tithanso kupereka majakisoni ndi machubu omwe amagwirizana ndi ma jakisoni otchuka a CT,MRI,DSA Ndi malingaliro awo owona komanso mphamvu zamaluso, onse ogwira ntchito ku LnkMed akukuitanani mowona mtima kuti mubwere kudzayendera limodzi misika yambiri.
