Imifanekiso yezonyango yesiNtu, esetyenziselwa ukuxilonga, ukubeka iliso okanye ukunyanga izifo ezithile, kudala kunzima ukufumana imifanekiso ecacileyo yezigulana ezinolusu olumnyama, iingcali zithi.
Abaphandi baye benza isaziso sokuba baye bafumanisa indlela yokuphucula imifanekiso yezonyango, evumela oogqirha ukuba bajonge ngaphakathi emzimbeni, kungakhathaliseki ibala lolusu.
Izinto ezifunyenweyo zamva nje zikhutshwe kwimagazini ka-Oktobha yephephancwadi Photoacoustics. Iqela labaphandi lenze iimvavanyo kwiingalo zamavolontiya ali-18, aquka abantu abanebala lemibala yesikhumba. Iziphumo zabo zibonise ulungelelwaniso phakathi kweqondo le-clutter, ukuphazamiseka kwesignali ye-photoacoustic echaphazela ukucaca kwe-imaging, kunye nobumnyama besikhumba.
“Ngokusisiseko ulusu lusebenza njengesixhobo sokuhambisa isandi, kodwa aludluliseli uhlobo olufanayo lwesandi esigxininisiweyo esifumaneka kwi-ultrasound. Endaweni yoko, isandi sisasazeke kulo lonke kwaye sibangela ukubhideka okukhulu, ”utshilo uBell. "Ngenxa yoko, ukusasazeka kwesandi ngenxa yokufunxa i-melanin kuya kuba yingxaki njengoko i-melanin ikhula."
Ukutshintsha ubuchule
Uphando, oluqhutywe ngokubambisana nabaphandi baseBrazil ababenamava ngaphambili kunye ne-algorithms yeBell, lubonise ukuba umlinganiselo we-signal-to-noise ratio, i-metric yesayensi yokuthelekisa amandla omqondiso kwingxolo yangasemva, yongezwa kuzo zonke iithoni zesikhumba xa abaphandi baqeshwe. indlela eyaziwa ngokuba yi "short-lag spatial coherence beamforming" ngexesha lomfanekiso wezonyango. Obu buchule, ekuqaleni benzelwe ukubonwa kwe-ultrasound, bunamandla okulungelelaniswa ukuze busetyenziswe kwi-photoacoustic imaging.
Indlela idibanisa zombini ukukhanya kunye nobuchwepheshe be-ultrasound ukudala indlela entsha yokucinga yezokwelapha, njengoko kuchazwe nguTheo Pavan, onxulumene nesebe le-physics kwiYunivesithi yaseSão Paulo eBrazil. NgokukaPavan, uphando lwabo luqinisekisile ukuba obu buchule butsha abuphenjelelwa kakhulu ngumbala wolusu, okukhokelela kumgangatho ophezulu womfanekiso xa kuthelekiswa neendlela eziqhelekileyo ezisetyenziswa ebaleni.
Abaphandi baqaphele ukuba uphononongo lwabo lolokuqala ukwenza uvavanyo lwenjongo yethoni yesikhumba kunye nokubonelela ubungqina obubambekayo kunye nobuninzi obubonisa ukuba isignali ye-photoacoustic yesikhumba kunye ne-clutter artifacts yandiswa njengoko umxholo we-epidermal melanin usanda.
Ukucinga ngokutsha okubanzi kukhathalelo lwempilo
Iziphumo zabaphandi zinokuba nempembelelo ebalulekileyo ekukhuthazeni ukulingana kukhathalelo lwezempilo kwizinga elibanzi. UCamara Jones, ugqirha weentsapho, ugqirha wezifo zezifo, kunye nowayesakuba ngumongameli woMbutho wezeMpilo woLuntu waseMelika, owayengabandakanyekanga kolu phando, wabalaselisa ukuthambekela kobuchwephesha bezenzululwazi ngokuthanda iimveliso ezisebenza ngakumbi kubantu abanolusu olukhaphukhaphu.UJones wagxininisa ukuba ukusebenzisa ubuhlanga njengento ebeka umngcipheko kwimpilo ngumba obalulekileyo, njengoko lululwakhiwo lwentlalo olusekwe kutoliko loluntu lwenkangeleko yenyama kunemiba yebhayoloji. Ubonise ukungabikho kwesiseko sofuzo kwi-racial sub-speciation kwi-genome yomntu njengobungqina bokuxhasa le ngxelo. Uphando lwangaphambili luye lwachonga ukuthambekela kwethoni yesikhumba kubuchwepheshe bezonyango, kunye neziphumo ezibonisa ukuba izixhobo zonyango ezisebenzisa i-infrared sensing zinokuthi zingasebenzi ngokufanelekileyo. kwisikhumba esimnyama ngenxa yokuphazamiseka okunokubakho ngokubonakalisa ukukhanya.
UBell uvakalise ithemba lokuba uphando lwakhe lunokuvula umnyango wokuphelisa umkhethe kukhathalelo lwempilo kwaye lukhuthaze abanye ukuba benze itekhnoloji enceda bonke abantu, ngaphandle kwebala lolusu lwabo.
"Ndiyakholelwa ukuba ngokukwazi ukubonisa ukuba sinokuyila kwaye siphuhlise itekhnoloji - loo nto ayisebenzi nje iseti enye yabemi kodwa isebenzela uluhlu olubanzi lwabemi. Oku kuyakhuthaza kakhulu kungekuphela nje kwiqela lam, kodwa kumaqela ehlabathini lonke ukuba aqalise ukucinga kweli cala xa kuyilwa iteknoloji. Ngaba inceda abantu abaninzi?” Watsho uBell.

Njengoko sonke siyazi, ukuphuhliswa kwemboni yezobuchwephesha zonyango ayinakuhlukaniswa nokuphuhliswa koluhlu lwezixhobo zonyango - ii-injection ze-agent echaseneyo kunye nezinto ezixhasayo - ezisetyenziswa kakhulu kule ndawo. E-China, edume ngoshishino lwayo lokuvelisa, baninzi abavelisi abadumileyo ekhaya nakwamanye amazwe ngokuveliswa kwezixhobo zonyango zonyango, kuquka.LnkMed. Ukusukela ekusekweni kwayo, i-LnkMed ibigxile kwintsimi yee-ejenti zokuchasa ngoxinzelelo oluphezulu. Iqela lobunjineli be-LnkMed likhokelwa yi-Ph.D. uneminyaka engaphezu kweshumi yamava kwaye uzibandakanye nzulu kuphando nophuhliso. Phantsi kokhokelo lwakhe, iCT isitofu sentloko enye,CT isitofu sentloko kabini,Isitofu se-agent ye-MRI yokuchasana, kwayeI-Angiography yoxinzelelo oluphezulu lwe-ejenti yokuchasaziyilwe ngezi mpawu: umzimba owomeleleyo noxineneyo, ujongano olufanelekileyo nolukrelekrele lokusebenza, imisebenzi epheleleyo, ukhuseleko oluphezulu, kunye noyilo oluhlala ixesha elide. Sinokubonelela ngeesirinji kunye netyhubhu ehambelana nezo mpawu zidumileyo ze-CT, iMRI, ii-injection ze-DSA Ngesimo sabo sengqondo esinyanisekileyo kunye namandla obuchwephesha, bonke abasebenzi be-LnkMed bayakumema ngokunyanisekileyo ukuba uze uhlolisise iimarike ezininzi kunye.
