Yiziphi Intuthuko Yakamuva Emfanekisweni Wezokwelapha?

Kusukela imvelaphi yawo ngeminyaka yawo-1960 kuya ko-1980, I-Magnetic Resonance Imaging (MRI), i-computerized tomography (CT) scan, kanye nezikena ze-positron emission tomography (PET) ziye zaba nentuthuko enkulu. Lawa mathuluzi wokucabanga wezokwelapha angahlaseli aqhubekile nokuvela ngokuhlanganiswa kobuhlakani bokwenziwa (AI), amasu athuthukisiwe okuqoqwa kwedatha eluhlaza, nokuhlaziywa kwezibalo zepharamitha eningi, konke okunikela ekuqondeni okuthuthukisiwe nokuhlaziywa kwezinhlelo zethu zangaphakathi.

Ukuthuthukiswa kokuskena kwe-PET ne-CT

Ukuskena okujwayelekile kwe-PET ngokuvamile kudinga phakathi kwemizuzu engu-45 nehora ukuze kuqedwe futhi kungaveza izithombe ezihlukile zokukhula kwesimila ebuchosheni, emaphashini, emlonyeni wesibeletho, nakwezinye izingxenye zomzimba. Intuthuko eqhubekayo ithuthukise ukusebenza kwale ndlela, ehlanganisa isofthiwe yokulungiswa kokufiphala kokunyakaza kanye nokuvumela ukuhlola kwe-algorithmic ukulindela indawo yenqwaba ngaphakathi kwezicubu ezihambayo.

Ukufiphala kokunyakaza kwenzeka lapho ingxenye eqondiwe ihamba ngesikhathi sokuthwebula isithombe se-PET, okwenza kube inselele kakhulu ukuhlola nokuhlaziya isisindo noma izicubu. Ukuze kuncishiswe ukunyakaza phakathi ne-PET scan, ochwepheshe bezokunakekelwa kwempilo basebenzisa ukuthengwa kwesango, behlukanisa umjikelezo wokuskena ube “imigqomo” eminingi. Ngokuhlukanisa inqubo yokuskena ibe yimigqomo engu-8-10, uhlelo lungalindela indawo yenqwaba eqondiwe ngesikhathi noma indawo ethile, ngokusekelwe kokuncamelayo komsebenzisi. Lesi sibikezelo senziwa ngokulindela indawo yenqwaba ngaphakathi kwemigqomo ngayinye yomjikelezo. Inqubo ye-PET imaging ye-PET inciphisa ngempumelelo ukufiphala kokunyakaza okungokwemvelo kudivayisi, okuholela ekugxilweni okuthuthukisiwe komsebenzi/inani lokubuyekeza elijwayelekile (i-SUV). Uma idatha ye-PET ihambisana nedatha ye-CT, yonke inqubo yaziwa ngokuthi i-4D CT scanning.

Noma kunjalo, kunomkhawulo owaziwayo ohlobene nale nqubo. Ukusebenzisa izindlela ezinesango zokutholwa kwesithombe kubangela umsindo ohlobene okhuphukile ngenxa yokutholwa kwenani elikhulu kakhulu ledatha. Amasu amaningana okubhekana nale nkinga ahlanganisa i-Q-freeze, i-Oncofreeze, nesikhathi sendiza (ToF).

Indlela ukufiphala kwesithombe kulungiswa ngayo phakathi kwe-PET ne-CT scan

Ukulungiswa okusekelwe ku-Q-freeze, kusetshenziswa ukutholwa kwesango, kuhlanganisa ukuqoqwa nokubhaliswa kwazo zonke izithombe ezikhiqiziwe. Lokhu kubhaliswa kwenzeka ngaphakathi kwendawo yesithombe, kuqoqwa futhi kwakhiwe kabusha yonke idatha eluhlaza etholwe kuskena se-PET ukuze kukhiqizwe isithombe sokugcina esinomsindo oncishisiwe nokufiphala.

I-OncoFreeze, indlela yesoftware yokwenza isibuko, ifana ne-Q-freeze ngezindlela ezithile, noma ihluke ngokuphelele. Ukulungiswa kokunyakaza kwenziwa esikhaleni se-sinogram (isikhala sedatha eluhlaza). Ngemva kokuthola isithombe sokuqala, izithombe ezilandelayo ezilufifi ziboniswa phambili futhi ziqhathaniswa nedatha yebhentshi lomsebenzi wokuhlinza kanye nezilinganiso ze-backproject sinogram. Lokhu kuholela esithombeni sokugcina esibuyekeziwe esisekelwe esithombeni sokulungiswa okufiphaziwe.

Ukuthwebula amaza okuphefumula ngesikhathi sokuskena kwe-PET kuhlanganiswe nezikena ze-CT kungaholela ekuthuthukisweni kwekhwalithi yesithombe. Ukuqondanisa okuthuthukisiwe kungafanekiswa ngokuvumelanisa amagagasi e-PET scans, indlela evamile, namagagasi e-CT scans, indlela esanda kuthuthukiswa.

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, I-CT double head injector, 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.
