Zithini izinto eziphuhlisiweyo kutshanje kwi-Medical Imaging?

Ukususela oko zaqala ngeminyaka yoo-1960 ukuya kowama-1980, iMagnetic Resonance Imaging (MRI), i-computerized tomography (CT) scans, kunye ne-positron emission tomography (PET) scans ziye zaphucuka kakhulu. Ezi zixhobo ze-medical imaging ezingezizo ezihlaselayo ziye zaqhubeka nokukhula ngokudityaniswa kobukrelekrele bokwenziwa (AI), iindlela eziphuculweyo zokuqokelelwa kwedatha eluhlaza, kunye nohlalutyo lwezibalo olune-multi-parametric, zonke ezi zixhobo zinegalelo ekuqondeni ngcono kunye nohlalutyo lweenkqubo zethu zangaphakathi.

Uphuculo kwi-PET kunye ne-CT scans

I-PET scan eqhelekileyo idla ngokuthatha imizuzu engama-45 kunye neyure ukuze igqitywe kwaye inokuvelisa imifanekiso eyahlukileyo yokukhula kwethumba engqondweni, emaphaphu, emlonyeni, nakwezinye iindawo zomzimba. Ukuqhubela phambili okuqhubekekayo kuphucule ukusebenza kwale ndlela, kubandakanya isoftware yokulungisa ukufiphala kwentshukumo kunye nokwenza uvavanyo lwe-algorithmic luqikelele indawo yobunzima kwizicubu ezihambayo.

Ukufiphalisa intshukumo kwenzeka xa icandelo elijoliswe kulo lihamba ngexesha lokufotwa komfanekiso we-PET scan, okwenza kube nzima ngakumbi ukuvavanya nokuhlalutya ubunzima okanye izicubu. Ukunciphisa intshukumo ngexesha lokuskena kwe-PET, iingcali zonyango zisebenzisa ukufunyanwa okuvalelweyo, zahlula umjikelo wokuskena ube "ziibhini" ezininzi. Ngokuhlulahlula inkqubo yokuskena ibe ziibini ezisi-8-10, inkqubo inokuqikelela indawo yobunzima ekujoliswe kuyo ngexesha okanye kwindawo ethile, ngokusekelwe kukhetho lomsebenzisi. Olu qikelelo lwenziwa ngokuqikelela indawo yobunzima ngaphakathi kwezibini zomjikelo ngamnye. Inkqubo yokufota nge-PET evalelweyo inciphisa ngokufanelekileyo ukufiphalisa intshukumo okukhoyo kwisixhobo, okubangela ukuphuculwa koxinzelelo lomsebenzi/ixabiso lohlaziyo olusemgangathweni (SUV). Xa idatha ye-PET ihambelana nedatha ye-CT, yonke inkqubo yaziwa ngokuba yi-4D CT scanning.

Nangona kunjalo, kukho umda owaziwayo onxulumene nale nkqubo. Ukusebenzisa iindlela ezivaliweyo zokufumana imifanekiso kubangela ingxolo eyandayo ngenxa yokufumana idatha eninzi kakhulu. Amaqhinga aliqela okujongana nale ngxaki aquka i-Q-freeze, i-Oncofreeze, kunye nexesha lokubhabha (ToF).

Indlela elungiswa ngayo ukufiphala komfanekiso kwi-PET kunye ne-CT scans

Ukulungiswa komfanekiso okusekelwe kwi-Q-freeze, kusetyenziswa ukufunyanwa kwesango, kubandakanya ukuqokelelwa nokubhaliswa kwayo yonke imifanekiso eyenziweyo. Olu bhaliso lwenzeka kwindawo yomfanekiso, ukuqokelela nokwakha kwakhona yonke idatha eluhlaza efunyenwe kwi-PET scan ukuvelisa umfanekiso wokugqibela onongxolo oluncinci kunye nokufiphala.

I-OncoFreeze, indlela yesoftware yokujongisa, ihambelana ne-Q-freeze ngeendlela ezithile, nangona yahlukile ngokubanzi. Ukulungiswa kwentshukumo kwenziwa kwindawo ye-sinogram (indawo yedatha eluhlaza). Emva kokufumana umfanekiso wokuqala, imifanekiso elandelayo efipheleyo iboniswa phambili kwaye ithelekiswa nedatha eqikelelweyo yebhentshi yomsebenzi wotyando kunye ne-backproject sinogram ratios. Oku kukhokelela kumfanekiso wokugqibela ohlaziyiweyo ngokusekelwe kumfanekiso wokulungiswa ohlulwe.

Ukubamba ii-waveforms zokuphefumla ngexesha le-PET scans kunye ne-CT scans kunokukhokelela ekuphuculeni umgangatho womfanekiso. Ulungelelwaniso oluphuculweyo lunokubonakaliswa ngokuvumelanisa ii-waveforms ze-PET scans, indlela eqhelekileyo, kunye nee-waveforms ze-CT scans, indlela esandul’ ukuphuhliswa.

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.
