Iingcali zithi imifanekiso yezonyango yendabuko, esetyenziselwa ukuxilonga, ukujonga okanye ukunyanga izifo ezithile, ibisoloko inengxaki yokufumana imifanekiso ecacileyo yezigulana ezinesikhumba esimnyama.
Abaphandi babhengeze ukuba bafumene indlela yokuphucula imifanekiso yezonyango, nto leyo evumela oogqirha ukuba bajonge ngaphakathi emzimbeni, nokuba ulusu lunjani na.
Izinto ezifunyenweyo zamva nje zikhutshwe kwiphephancwadi i-Photoacoustics ka-Okthobha. Iqela labaphandi lenze uvavanyo kwiingalo zamavolontiya ali-18, luquka abantu abaneempawu ezahlukeneyo zesikhumba. Iziphumo zabo zityhile unxibelelwano phakathi kobungakanani bokuxinana, ukugqwetheka komqondiso we-photoacoustic ochaphazela ukucaca kwemifanekiso, kunye nobumnyama besikhumba.
“Ulusu lusebenza njengesixhobo sokudlulisa isandi, kodwa aludluliseli uhlobo olufanayo lwesandi esijoliswe kwi-ultrasound. Endaweni yoko, isandi sisasazeka kuyo yonke indawo kwaye sibangela ukudideka okukhulu,” utshilo uBell. “Ngenxa yoko, ukusasazeka kwesandi ngenxa yokufunxwa kwe-melanin kuba yingxaki ngakumbi njengoko uxinano lwe-melanin lusanda.”
Ukutshintsha indlela
Olu phando, olwenziwe ngokubambisana nabaphandi baseBrazil ababenamava ngaphambili ngenye yee-algorithms zikaBell, lutyhile ukuba umlinganiselo wesignali-kwingxolo, i-metric yesayensi yokuthelekisa amandla esignali nengxolo yangasemva, waphuculwa kuzo zonke iithoni zesikhumba xa abaphandi basebenzisa indlela eyaziwa ngokuba yi-"short-lag spatial coherence beamforming" ngexesha lomfanekiso wezonyango. Le ndlela, eyayiyilwe okokuqala kwi-ultrasound imaging, inako ukulungelelaniswa nokusetyenziswa kwi-photoacoustic imaging.
Le ndlela idibanisa zombini ubuchwepheshe bokukhanya kunye ne-ultrasound ukudala indlela entsha yokufota ngezonyango, njengoko kuchaziwe nguTheo Pavan, onxulumene nesebe lefiziksi kwiYunivesithi yaseSão Paulo eBrazil. Ngokutsho kukaPavan, uphando lwabo luqinisekisile ukuba le ndlela intsha ayichaphazeleki kakhulu ngumbala wolusu, nto leyo ebangela umgangatho womfanekiso ophezulu xa kuthelekiswa neendlela eziqhelekileyo ezisetyenziswa kakhulu kweli candelo.
Abaphandi baqaphele ukuba uphando lwabo lolona lokuqala lokwenza uvavanyo oluchanekileyo lwethoni yolusu kunye nokubonelela ngobungqina obuchanekileyo nobunobungakanani obubonisa ukuba isignali ye-photoacoustic yolusu kunye nezinto ezingafunekiyo ziyanda njengoko umxholo we-melanin ye-epidermal usanda.
Ukucinga ngokutsha ngokubanzi kukhathalelo lwempilo
Iziphumo zabaphandi zinokuba nefuthe elikhulu ekukhuthazeni ubulungisa kwezempilo ngokubanzi. UGqr. Camara Jones, ugqirha wosapho, ingcali yezifo ezibangelwa yintsholongwane, kunye nomongameli wangaphambili we-American Public Health Association, owayengabandakanyekanga kolu phando, ugxininise ukuthambekela kwitekhnoloji yesayensi ekukhetheni iimveliso ezisebenzayo ngakumbi kubantu abanesikhumba esikhanyayo. UJones ugxininise ukuba ukusebenzisa uhlanga njengento ebeka emngciphekweni impilo yingxaki ebalulekileyo, njengoko kuyilo lwentlalo olusekelwe kwiindlela zoluntu zokujonga inkangeleko yomzimba kunokuba kube zizinto zebhayoloji. Ukhankanye ukungabikho kwesiseko semfuza sohlobo oluthile lohlanga kwi-genome yomntu njengobungqina bokuxhasa le ngxelo. Uphando lwangaphambili lukwachonge ukuthambekela kwesikhumba kwitekhnoloji yezonyango, kunye neziphumo ezibonisa ukuba izixhobo zonyango ezisebenzisa i-infrared sensing zisenokungasebenzi kakuhle kulusu olumnyama ngenxa yokuphazamiseka okunokwenzeka kokukhanya.
UBell uvakalise ithemba lokuba uphando lwakhe lunokuvula indlela yokuphelisa ucalucalulo kwezempilo kwaye lukhuthaze abanye ukuba benze itekhnoloji enceda bonke abantu, kungakhathaliseki ukuba banombala onjani na wesikhumba.
“Ndikholelwa ukuba ngokukwazi ukubonisa ukuba singayila kwaye siphuhlise iteknoloji — oko akusebenzi nje kuphela kwiqela elincinci labemi kodwa kusebenza kuluhlu olubanzi lwabemi. Oku kuyakhuthaza kakhulu kungekuphela nje kwiqela lam, kodwa nakumaqela kwihlabathi liphela ukuba aqale ukucinga ngale ndlela xa eyila iteknoloji. Ngaba iyabanceda abantu abaninzi?” utshilo uBell.

Njengoko sonke sisazi, uphuhliso lweshishini lemifanekiso yezonyango alunakwahlulwa kuphuhliso lwezixhobo zonyango ezininzi - ii-contrast agent injectors kunye nezinto ezisetyenziswayo ezixhasayo - ezisetyenziswa kakhulu kweli candelo. E-China, edume ngeshishini layo lokuvelisa, kukho abavelisi abaninzi abadumileyo ekhaya nakwamanye amazwe ngokuvelisa izixhobo zemifanekiso yezonyango, kuqukaI-LnkMedUkususela oko yasekwa, iLnkMed ibigxile kwicandelo lee-injectors ze-contrast agents ezinoxinzelelo oluphezulu. Iqela lobunjineli leLnkMed likhokelwa yiPh.D. enamava angaphezu kweminyaka elishumi kwaye ibandakanyeka kakhulu kuphando nophuhliso. Phantsi kwesikhokelo sakhe,I-CT single head injector,I-CT double head injector,I-MRI contrast agent injectorkunyeI-Angiography yoxinzelelo oluphezulu lwe-contrast agent injectorZenzelwe ezi mpawu zilandelayo: umzimba oqinileyo nomncinci, ujongano lokusebenza olulula nolukrelekrele, imisebenzi epheleleyo, ukhuseleko oluphezulu, kunye noyilo oluhlala ixesha elide. Singabonelela ngeesirinji kunye neetyhubhu ezihambelana nezo mpawu zidumileyo zee-injectors ze-CT, MRI, DSA Ngenxa yesimo sabo sengqondo esinyanisekileyo kunye namandla abo obuchwephesha, bonke abasebenzi be-LnkMed bayanimema ngokunyanisekileyo ukuba nize nihlole iimarike ezininzi kunye.
