Imifanekiso yendabuko yezokwelapha, esetshenziselwa ukuxilonga, ukuqapha noma ukwelapha izifo ezithile, kudala kunzima ukuthola izithombe ezicacile zeziguli ezinesikhumba esimnyama, kusho ochwepheshe.
Abacwaningi baye bamemezela ukuthi bathole indlela yokuthuthukisa izithombe zezokwelapha, okuvumela odokotela ukuba bahlole ingaphakathi lomzimba, kungakhathaliseki ukuthi ibala lesikhumba linjani.
Okutholakele kwakamuva kukhishwe kumagazini ka-Okthoba wephephabhuku i-Photoacoustics. Iqembu labacwaningi lenze izivivinyo ezingalweni zamavolontiya angu-18, okuhlanganisa abantu abanenqwaba yamathoni esikhumba. Okutholakele kwabo kwembule ukuhlobana phakathi kwezinga lemfuhlumfuhlu, ukuhlanekezela kwesignali ye-photoacoustic ethinta ukucaca kwezithombe, nobumnyama besikhumba.
Isikhumba empeleni sisebenza njengesidluliseli somsindo, kodwa asidluliseli uhlobo olufanayo lomsindo ogxilile otholakala kuyi-ultrasound. Kunalokho, umsindo usakazeka yonke indawo futhi ubangela ukudideka okukhulu,” kusho uBell. "Ngenxa yalokho, ukusakazeka komsindo ngenxa yokumuncwa kwe-melanin kuba yinkinga kakhulu njengoba i-melanin ikhula."
Ukushintsha indlela yokwenza
Ucwaningo, olwenziwa ngokubambisana nabacwaningi base-Brazil ababenolwazi lwangaphambili nge-algorithms eyodwa ye-Bell, luveze ukuthi isilinganiso sesignali-kuya-nomsindo, imethrikhi yesayensi yokuqhathanisa amandla esignali nomsindo wangemuva, yathuthukiswa kuzo zonke izicubu zesikhumba lapho abacwaningi basebenzisa indlela eyaziwa ngokuthi “i-short-lag spatial coherence beamforming” ngesikhathi sokuthwebula kwezokwelapha. Le nqubo, ekuqaleni eyenzelwe i-ultrasound imaging, inamandla okushintshwa ukuze isetshenziswe ekuthwebuleni kwezithombe ze-photoacoustic.
Le ndlela ihlanganisa kokubili ubuchwepheshe obukhanyayo kanye ne-ultrasound ukudala indlela entsha yokucabanga yezokwelapha, njengoba kuchazwe u-Theo Pavan, ohlotshaniswa nomnyango we-physics eNyuvesi yase-São Paulo e-Brazil. Ngokusho kukaPavan, ucwaningo lwabo luqinisekisile ukuthi le nqubo entsha ayithonywa kakhulu umbala wesikhumba, okuholela ekhwalithi ephezulu yesithombe uma kuqhathaniswa nezindlela ezivamile ezivame ukusetshenziswa ensimini.
Abacwaningi baqaphele ukuthi ucwaningo lwabo olokuqala lokuhlola ithoni yesikhumba kanye nokuhlinzeka kokubili ubufakazi bekhwalithi nobungako obubonisa ukuthi isignali ye-photoacoustic yesikhumba kanye nezinto zokwenziwa ze-clutter ziyakhuliswa njengoba okuqukethwe kwe-epidermal melanin kwanda.
Ukucabanga kabusha okubanzi ekunakekelweni kwezempilo
Okutholwe ngabacwaningi kungase kube nomthelela omkhulu ekukhuthazeni ukulingana ekunakekelweni kwezempilo ngezinga elibanzi.UDkt. UCamara Jones, udokotela womndeni, udokotela wezifo eziwumshayabhuqe, kanye nowayengumongameli we-American Public Health Association, owayengahileleki kulolu cwaningo, wagqamisa ukuchema kobuchwepheshe besayensi ngokuvuna imikhiqizo esebenza kangcono kubantu abanesikhumba esikhanyayo. Uveze ukungabi bikho kwesisekelo sofuzo sokucaciswa kwe-racial sub-speciation ku-genome yomuntu njengobufakazi obusekela lokhu kugomela. Ucwaningo lwangaphambili luphinde lwahlonza ukuchema kwethoni yesikhumba kubuchwepheshe bezokwelapha, nokutholakele okubonisa ukuthi imishini yezokwelapha esebenzisa i-infrared sensing ingase ingasebenzi ngendlela ephumelelayo esikhumbeni esimnyama ngenxa yokuphazamiseka okungase kube nokubonakaliswa kokukhanya.
U-Bell uzwakalise ukuthi unethemba lokuthi ucwaningo lwakhe lungavula umnyango wokuqeda ukuchema ekunakekelweni kwezempilo futhi lukhuthaze abanye ukuthi bakhe ubuchwepheshe obuzuzisa bonke abantu, kungakhathaliseki ibala lesikhumba sabo.
"Ngikholwa ukuthi ngekhono lokukhombisa ukuthi singakwazi ukusungula nokuthuthukisa ubuchwepheshe - lokho akusebenzi nje eqenjini elincane labantu kodwa kusebenzela inqwaba yabantu abaningi. Lokhu akukhuthazi kakhulu hhayi kuphela iqembu lami, kodwa emaqenjini omhlaba wonke ukuthi aqale ukucabanga ngale ndlela lapho eklama ubuchwepheshe. Ingabe kusiza abantu abaningi?" Kusho uNsimbi.

Njengoba sonke sazi, ukuthuthukiswa kwemboni yezithombe zezokwelapha akunakuhlukaniswa nokuthuthukiswa kochungechunge lwemishini yezokwelapha - ama-ejenti e-agent ehlukile kanye nezinto ezisetshenziswayo ezisekelayo - ezisetshenziswa kakhulu kulo mkhakha. E-China, edume ngemboni yayo yokukhiqiza, kunabakhiqizi abaningi abadumile ekhaya naphesheya ngokukhiqizwa kwemishini yokuthwebula yezokwelapha, okuhlanganisa.I-LnkMed. Selokhu yasungulwa, i-LnkMed ibilokhu igxile emkhakheni wama-ejenti wokuqhathanisa nengcindezi ephezulu. Ithimba lonjiniyela be-LnkMed liholwa yi-Ph.D. unolwazi olungaphezu kweminyaka eyishumi futhi ubambe iqhaza ngokujulile ocwaningweni nasekuthuthukisweni. Ngaphansi kokuqondisa kwakhe, iCT umjovo wekhanda elilodwa,CT umjovo wekhanda kabili,Umjovo we-ejenti yokuqhathanisa ye-MRI, futhiUmjovo we-angiography wokucindezela okuphezulu kokungafaniaklanywe ngalezi zici: umzimba oqinile futhi ohlangene, isixhumi esibonakalayo esisebenzayo nesihlakaniphile, imisebenzi ephelele, ukuphepha okuphezulu, kanye nomklamo oqinile. Futhi singahlinzeka ngamasirinji namashubhu ahambisana nalezo zinhlobo ezidumile zamajovo e-CT,MRI,DSA Ngesimo sabo sengqondo esiqotho namandla ochwepheshe, bonke abasebenzi be-LnkMed bakumema ngobuqotho ukuthi nize nizohlola izimakethe ezengeziwe ndawonye.
