Lefapheng la litšoantšo tsa bongaka le tlhahlobo ea mafu, theknoloji ea X-ray e phethile karolo ea bohlokoa ka lilemo tse mashome.Har'a likarolo tse sa tšoaneng tse etsang mochine oa X-ray, tube e tsitsitseng ea anode X-ray e fetohile karolo ea bohlokoa ea thepa.Li-tubes tsena ha li fane feela ka mahlaseli a hlokahalang bakeng sa ho nka litšoantšo, empa hape li khetholla boleng le katleho ea tsamaiso eohle ea X-ray.Ho blog ena, re tla hlahloba mekhoa ea li-tubes tsa X-ray tse tsitsitseng le kamoo tsoelo-pele ea theknoloji e fetolang karolo ena ea bohlokoa kateng.
Ho tloha qalong ho fihlela incarnation ea kajeno:
Li-tubes tsa X-ray tsa anodee na le nalane e telele ea ho sibolloa ha X-ray la pele ke Wilhelm Conrad Roentgen mathoasong a lekholo la bo20 la lilemo.Qalong, li-tubes li ne li e-na le kampo e bonolo ea khalase e nang le cathode le anode.Ka lebaka la boemo ba eona bo phahameng ba ho qhibiliha, anode hangata e entsoe ka tungsten, e ka pepesehelang phallo ea elektronike nako e telele ntle le tšenyo.
Ha nako e ntse e ea, ha tlhokahalo ea litšoantšo tse nepahetseng le tse nepahetseng e ntse e eketseha, ho entsoe tsoelo-pele e kholo moralong le kahong ea li-tubes tsa X-ray tse emeng.Ho kenngoa ha li-anode tubes tse pota-potileng le nts'etsopele ea lisebelisoa tse matla ho lumella ho eketseha ha mocheso oa mocheso le matla a phahameng a matla.Leha ho le joalo, litšenyehelo le ho rarahana ha li-anode tubes tse potolohang li fokolitse ho amoheloa ha tsona hohle, ho etsa hore li-anode tubes e be khetho e ka sehloohong bakeng sa litšoantšo tsa bongaka.
Mekhoa ea morao-rao ea li-anode X-ray tubes tse tsitsitseng:
Haufinyane tjena, ntlafatso e kholo ea thekenoloji e lebisitse ho tsosoloseng botumo ba li-fixed-anode X-ray tubes.Lintlafatso tsena li thusa ho ntlafatsa bokhoni ba ho nka litšoantšo, matla a phahameng a matla, le ho hanyetsa mocheso o moholo, ho etsa hore li tšepahale le ho sebetsa hantle ho feta leha e le neng pele.
Mokhoa o hlokomelehang ke tšebeliso ea litšepe tse refractory joalo ka molybdenum le li-alloys tsa tungsten-rhenium joalo ka lisebelisoa tsa anode.Litšepe tsena li na le khanyetso e ntle ea mocheso, e lumellang li-tubes ho mamella maemo a phahameng a matla le nako e telele ea ho pepeseha.Tsoelo-pele ena e tlatselitse haholo ntlafatsong ea boleng ba setšoantšo le ho fokotsa nako ea ho nka litšoantšo ka mokhoa oa ho hlahloba.
Ho feta moo, ho hlahisitsoe mokhoa o mocha oa ho pholisa ho ikarabella bakeng sa mocheso o hlahisoang nakong ea tlhahiso ea X-ray.Ka ho eketsoa ha tšepe ea metsi kapa li-anode tse entsoeng ka mokhoa o khethehileng, matla a ho qhala mocheso oa li-anode tubes tse tsitsitseng a matlafatsoa haholo, ho fokotsa kotsi ea ho chesa le ho lelefatsa bophelo bohle ba li-tubes.
Tloaelo e 'ngoe e thabisang ke ho kopanngoa ha mahlale a morao-rao a ho nahana joalo ka li-detectors tsa dijithale le li-algorithms tsa ts'ebetso ea litšoantšo tse nang le li-tubes tse tsitsitseng tsa X-ray.Ho kopanya hona ho lumella tšebeliso ea mekhoa e tsoetseng pele ea ho fumana litšoantšo tse kang digital tomosynthesis le cone beam computed tomography (CBCT), e leng se fellang ka tsosoloso e nepahetseng haholoanyane ea 3D le ho ntlafatsa tlhahlobo ea mafu.
ha re phethela:
Qetellong, mokhoa o lebisangli-tubes tsa X-ray tse emeng tsa anode e lula e fetoha ho fihlela litlhoko tsa litšoantšo tsa morao-rao tsa bongaka.Tsoelo-pele ea thepa, mekhoa ea ho pholisa, le ho kopanngoa ha mahlale a morao-rao a ho etsa litšoantšo a fetotse karolo ena ea bohlokoa ea mekhoa ea X-ray.Ka lebaka leo, litsebi tsa tlhokomelo ea bophelo bo botle li se li ka fa bakuli boleng ba setšoantšo se betere, ho pepesetsoa mahlaseli a fokolang le tlhaiso-leseling e nepahetseng haholoanyane ea tlhahlobo.Ho hlakile hore li-tubes tse tsitsitseng tsa X-ray tsa anode li tla tsoela pele ho phetha karolo ea bohlokoa litšoantšong tsa bongaka, ho khanna mekhoa e mecha le ho kenya letsoho ntlafatsong ea tlhokomelo ea mokuli.
