Mafapheng a ho nka ditshwantsho tsa bongaka le ho hlahloba, theknoloji ya X-ray e bapetse karolo ya bohlokwa ka mashome a dilemo. Har'a dikarolo tse fapaneng tse etsang mochini wa X-ray, tube ya X-ray ya anode e tsitsitseng e fetohile karolo ya bohlokwa ya disebediswa. Di-tube tsena ha di fane feela ka mahlaseli a hlokahalang bakeng sa ho nka ditshwantsho, empa hape di fumana boleng le bokgoni ba sistimi yohle ya X-ray. Ho blog ena, re tla hlahloba mekgwa ya di-tube tsa X-ray tsa anode e tsitsitseng le kamoo kgatelopele ya theknoloji e fetolang karolo ena ya bohlokwa kateng.
Ho tloha qalong ho isa ho tsoalo ea sejoale-joale:
Liphaephe tsa X-ray tse sa sisinyeheng tsa anodeli na le nalane e telele e qalileng ho tloha ha ho sibolloa ha X-ray ka lekhetlo la pele ke Wilhelm Conrad Roentgen mathoasong a lekholo la bo20 la lilemo. Qalong, lipeipi li ne li entsoe ka khalase e bonolo e koaletsoeng cathode le anode. Ka lebaka la ntlha ea eona e phahameng ea ho qhibiliha, anode hangata e entsoe ka tungsten, e ka pepesetsoang phallo ea lielektrone nako e telele ntle le tšenyo.
Ha nako e ntse e ya, ha tlhoko ea ho etsa litšoantšo tse nepahetseng le tse nepahetseng e ntse e hola, ho entsoe tsoelo-pele e kholo moralong le kahong ea li-tube tsa X-ray tsa anode e sa sisinyeheng. Ho hlahisoa ha li-tube tsa anode tse potolohang le nts'etsopele ea thepa e matla ho lumelletse ho eketseha ha ho qhalana ha mocheso le tlhahiso e phahameng ea matla. Leha ho le joalo, litšenyehelo le ho rarahana ha li-tube tsa anode tse potolohang ho fokolitse ho amoheloa ha tsona ka bongata, ho etsa hore li-tube tsa anode tse sa sisinyeheng e be khetho e ka sehloohong bakeng sa ho etsa litšoantšo tsa bongaka.
Mekhoa ea morao tjena ea li-tubes tsa X-ray tsa anode e tsitsitseng:
Morao tjena, lintlafatso tse kholo tsa theknoloji li lebisitse ho tsosolosoeng ha botumo ba lipeipi tsa X-ray tse nang le anode e tsitsitseng. Tsoelo-pele ena e nolofalletsa bokhoni bo ntlafetseng ba ho nka litšoantšo, tlhahiso e phahameng ea matla, le ho hanyetsa mocheso haholo, e leng se etsang hore li tšepahale le ho sebetsa hantle ho feta leha e le neng pele.
Mokhoa o hlokomelehang ke tšebeliso ea litšepe tse hanyetsang tse kang molybdenum le li-alloy tsa tungsten-rhenium e le thepa ea anode. Litšepe tsena li na le khanyetso e ntle ea mocheso, e lumellang lipeipi ho mamella maemo a phahameng a matla le linako tse telele tsa ho pepesehela. Nts'etsopele ena e kentse letsoho haholo ntlafatsong ea boleng ba setšoantšo le phokotso ea nako ea ho nka litšoantšo ts'ebetsong ea tlhahlobo.
Ho phaella moo, ho hlahisitswe mokgwa o motjha wa ho phodisa ho ikarabella bakeng sa mocheso o hlahiswang nakong ya ho ntsha X-ray. Ka ho eketswa ha tshepe e metsi kapa di-anode tse entsweng ka ho kgetheha, bokgoni ba ho qhala mocheso ba di-anode tse tsitsitseng bo eketswa haholo, e leng se fokotsang kotsi ya ho tjhesa haholo le ho atolosa bophelo bohle ba di-tube.
Mokhoa o mong o thabisang ke ho kopanngoa ha mahlale a sejoale-joale a ho nka litšoantšo a kang li-detector tsa dijithale le li-algorithms tsa ho sebetsana le litšoantšo ka li-tube tsa X-ray tse tsitsitseng tsa anode. Ho kopanngoa hona ho lumella tšebeliso ea mekhoa e tsoetseng pele ea ho fumana litšoantšo joalo ka tomosynthesis ea dijithale le cone beam computed tomography (CBCT), e leng se fellang ka ho tsosolosoa ha 3D ho nepahetseng haholoanyane le tlhahlobo e ntlafetseng.
ha re phethela:
Qetellong, tšekamelo e lebisang holiphaephe tsa X-ray tsa anode e sa sisinyeheng e ntse e fetoha kamehla ho fihlela litlhoko tsa litšoantšo tsa bongaka tsa sejoale-joale. Tsoelo-pele ea thepa, mekhoa ea ho pholisa, le kopanyo ea mahlale a morao-rao a litšoantšo a fetotse karolo ena ea bohlokoa ea litsamaiso tsa X-ray. Ka lebaka leo, litsebi tsa tlhokomelo ea bophelo bo botle joale li ka fa bakuli boleng bo betere ba setšoantšo, ho pepesehela mahlaseli a fokolang le tlhahisoleseling e nepahetseng haholoanyane ea tlhahlobo. Ho hlakile hore lipeipi tsa X-ray tsa anode e tsitsitseng li tla tsoela pele ho bapala karolo ea bohlokoa ho etseng litšoantšo tsa bongaka, ho khanna boqapi le ho kenya letsoho tlhokomelong e ntlafetseng ea bakuli.
