I-CBCT yamazinyo yezokwelapha isifinyezo se-Cone beam CT.Njengoba igama liphakamisa, iyithuluzi le-cone beam projection reconstruction computer tomography.Isimiso saso ukuthi i-X-ray generator yenza ukuskena okuyisiyingi ezungeze umzimba wokuqagela ngomthamo ophansi wemisebe (imvamisa i-current of tube imayelana ne-10 mA).Khona-ke, idatha etholwe "empambanweni yomgwaqo" ngemva kokuqagela kwedijithali ezungeze umzimba wokuqagela izikhathi eziningi (izikhathi ezingu-180 - izikhathi ezingu-360, kuye ngokuthi umkhiqizo) "ihlanganiswa kabusha futhi yakhiwe kabusha" kukhompyutha ukuze kutholwe isithombe esinezinhlangothi ezintathu.Umgomo wokuqagela wedatha etholwe yi-CBCT uhluke ngokuphelele kulowo we-CT scan yomkhakha wendabuko, futhi isimiso se-algorithm sokuhlelwa kabusha kwekhompyutha kamuva siyefana.
Nge-CBCT yamazinyo, umtshina wephaneli eyisicaba yiwona oyinhloko othinta ikhwalithi yesithombe sawo, kanye nomkhiqizo nokusebenza kobuchwepheshe komtshina wephaneli eyisicaba kuhlobene nekhwalithi yesithombe sawo.Umtshina wephaneli yephaneli ye-X-ray wamazinyo owenziwe ngokuzimela futhi waklanywa u-Haobo ucabangela izidingo ezithile zohlaka lwamazinyo oluncane kanye nezinga eliphezulu lozimele, futhi ulungele izicelo zokuhlolwa kwezokwelapha namazinyo.
Izincomo zomkhiqizo wehadiwe
