I-Medical Flat Panel Detectors vs Izihloli ze-Veterinary Flat Panel: Ukuqonda Umehluko
Ama-flat panel detectors ubuchwepheshe obuphambili obuguqule umkhakha wezithombe zezokwelapha nezilwane.Lawa madivayisi athathe indawo yamasistimu asuselwa kufilimu, anikezela ngezinzuzo ezimbalwa njengekhwalithi yesithombe ethuthukisiwe, ukutholwa kwesithombe ngokushesha, namandla okuxilonga athuthukisiwe.Kodwa-ke, kunomehluko oyinhloko phakathi kwezitholi zephaneli yezokwelapha nezezilwane okufanele zihlolwe.
Izithungatha zephaneli yezokwelapha eziyisicaba zenzelwe ngokukhethekile ukusetshenziswa ezikhungweni zokunakekelwa kwempilo yabantu.Lezi zitholi zisetshenziselwa izinqubo eziningi zokuxilonga zokuxilonga, okuhlanganisa ama-X-reyi, izikena ze-computed tomography (CT), i-mammography, ne-interventional radiology.Akhethekile kakhulu futhi alungiselelwe ukusetshenziswa ezithombeni zezokwelapha, ahlinzeka ngokulungiswa kwesithombe okuhlukile nokugqama.
Umehluko omkhulu phakathi kwezitholi zephaneli yezokwelapha nezilwane ezisesifundeni se-anatomy nosayizi weziguli ezisetshenziswa kuzo.Abantu banosayizi nokwakheka komzimba okuhluke kakhulu uma kuqhathaniswa nezilwane, okwenza kube nesidingo semishini yokuhlola ekhethekile.Izitholi zephaneli eyisicaba yezokwelapha zivame ukuba zinkulu ngosayizi futhi zinikeza indawo ebanzi yokuhlanganisa izinhlobo ezihlukahlukene zomzimba.Baphinde bahlonyiswe ngama-algorithms wokucubungula izithombe athuthukisiwe enzelwe i-anatomy yomuntu.
Ngakolunye uhlangothi, izithungatha zephaneli yezilwane eziyisicaba zenzelwe ukusetshenziswa emitholampilo yezilwane nasezikhungweni zezempilo zezilwane.Lezi zitholi zilinganiselwe futhi zenzelwe izilwane ezithwebulayo ezinosayizi abahlukahlukene, kusukela kuzilwane ezifuywayo ezincane njengamakati nezinja kuya ezilwaneni ezinkulu ezifana namahhashi nezinkomo.Izithungatha zincane ngosayizi uma ziqhathaniswa nezitholi zezokwelapha, okuvumela ukuma kalula kanye nokuhamba kahle lapho uthwebula izilwane.
Esinye isici esihlukanisayo phakathi kwezitholi zephaneli yezokwelapha nezezilwane kusekubeni lwezinhlelo ezisetshenziselwa zona.Nakuba imitshina yezokwelapha isetshenziselwa ngokuyinhloko ukuxilonga izithombe kanye nokungenelela ekunakekelweni kwezempilo kwabantu, izitholi zezilwane zisetshenziswa ezinhlobonhlobo zezinqubo zezilwane.Lokhu kufaka phakathi ukuthwebula izithombe zokuphuka nokulimala, ukuhlolwa kwempilo yamazinyo neyomlomo, ukuhlolwa kwesitho sangaphakathi, kanye nokusetshenziswa kwamathambo, phakathi kokunye.
I-software namandla okucutshungulwa kwezithombe ezitholi zezokwelapha nezilwane nazo ziyehluka.Izitholi zephaneli eyisicaba yezokwelapha zisebenzisa ama-algorithms athuthukile kanye nesofthiwe ukuthuthukisa ikhwalithi yesithombe, ukunciphisa ama-artifact, kanye nokwenza ngcono ukunemba kokuxilonga ezigulini ezingabantu.Ukwengeza, isofthiwe yokucabanga yezokwelapha ingase inikeze izici ezifana nokulandela umthamo wemithamo nokuphathwa, ezibalulekile ekuphepheni kwesiguli.Ngokuphambene, izitholi zezilwane zifakelwe isofthiwe eklanyelwe ngokukhethekile ukuthwebula izilwane, enezici eziklanyelwe ukubhekana nokwehluka kwesakhiwo kanye nezidingo ezithile zokuxilonga zezilwane.
Izindleko zingokunye okucatshangelwayo okubalulekile uma kuqhathaniswa imitshina yamaphaneli efulethi yezokwelapha kanye neyezilwane.Imitshina yezokwelapha ivamise ukumba eqolo ngenxa yezinga eliphezulu lobuchwephesha kanye nobuchwepheshe obuthuthukile obuhlanganisayo.Ukwengeza, izimfuno kanye nezindinganiso zokuthobela zezithombe zezokwelapha zivame ukuqina, okuholela ekuthuthukisweni okuphezulu kanye nezindleko zokukhiqiza.Izitholi zezilwane, nakuba zisathuthuke kakhulu kwezobuchwepheshe, ngokuvamile zithengeka kakhulu futhi zifinyeleleka emitholampilo yezilwane kanye nezinqubo.
Sengiphetha, ngenkathi imitshina yephaneli eyisicaba yezokwelapha neyezilwane yabelana ngokufana okuthile, yakhelwe ukuhlangabezana nezidingo ezithile zenkambu ngayinye.Izitholi zezokwelapha zikhulu ngosayizi, zilungiselelwe isimo somzimba womuntu, futhi zisetshenziswa ezinqubweni ezihlukahlukene zokuxilonga nezokungenela.Imishini yokubona izilwane, ngakolunye uhlangothi, iklanyelwe ukubeka kalula ezilwaneni ezinobukhulu obuhlukahlukene futhi isetshenziswa ezinhlobonhlobo zezinhlelo zokwelashwa kwezilwane.Ukuqonda lo mehluko kubalulekile ekukhetheni umtshina ofaneleka kakhulu endaweni efanele, ukuqinisekisa ukubonwa kwesithombe sokuxilonga nokunakekelwa kwesiguli.
