Ho tloha ha e qala, li-tubes tsa X-ray tsa bongaka li phethile karolo ea bohlokoa phetohong ea litšoantšo tsa tlhahlobo.Li-tubes tsena ke karolo ea bohlokoa ea mechine ea X-ray e lumellang lingaka ho bona ka hare ho bakuli le ho hlahloba maemo a fapaneng a bophelo.Ho utloisisa ts'ebetso e kahare ea li-tubes tsa X-ray tsa bongaka ho ka ntlafatsa kutloisiso ea rona ea tsoelo-pele ea theknoloji e sutumelletsang litšoantšo tsa tlhahlobo ho ea holimo.
Moko oa akalafi X-ray tubee na le likarolo tse peli tse kholo: cathode le anode, tse sebetsang hammoho ho hlahisa mahlaseli a X-ray.Cathode e sebetsa e le mohloli oa li-electrone ha anode e sebetsa e le sepheo sa li-electrone tsena.Ha matla a motlakase a sebelisoa ho tube, cathode e ntša molapo oa li-electrone, tse tsepamisitsoeng le ho potlakisa ho anode.
Cathode ke filament e futhumetseng, hangata e entsoeng ka tungsten, e ntšang lielektrone ka mokhoa o bitsoang thermionic emission.Motlakase o matla o futhumatsa khoele, o etsa hore lielektrone li tsoe holim'a eona 'me li etse leru la likaroloana tse mpe.Komiki e tsepamisitseng maikutlo e entsoeng ka nickel e ntan'o etsa leru la lielektrone hore e be leballo le moqotetsane.
Ka lehlakoreng le leng la tube, anode e sebetsa e le sepheo sa li-electrone tse hlahisoang ke cathode.Hangata anode e entsoe ka tungsten kapa lisebelisoa tse ling tse phahameng tsa athomo ka lebaka la sebaka se phahameng sa ho qhibiliha le bokhoni ba eona ba ho mamella mocheso o moholo o hlahisoang ke bombardment ea electron.Ha lielektrone tsa lebelo le phahameng li thulana le anode, li fokotsa lebelo ka potlako, li ntša matla ka sebōpeho sa X-ray photon.
E 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa molemong oa moralo oa X-ray tube ke bokhoni ba ho qhala mocheso o mongata o hlahisoang nakong ea ts'ebetso.E le ho finyella sena, tube ea X-ray e na le mokhoa o rarahaneng oa ho pholisa ho thibela ho chesa le ho senyeha ha anode.Lisebelisoa tsena tsa ho pholisa hangata li kenyelletsa ho potoloha ha oli kapa metsi ho potoloha anode, ho monya hantle le ho felisa mocheso.
Lehlaseli la X-ray le hlahisoang ke tube le ntse le bōptjoa ka ho eketsehileng le ho laoloa ke li-collimator, tse laolang boholo, matla le sebōpeho sa tšimo ea X-ray.Sena se lumella lingaka ho shebana le X-ray hantle libakeng tse khahlang, ho fokotsa ho pepesehela mahlaseli ho sa hlokahaleng ho bakuli.
Tsoelo-pele ea li-tubes tsa X-ray tsa bongaka li ile tsa fetola litšoantšo tsa ho hlahloba ka ho fa lingaka sesebelisoa se sa senyeheng sa ho bona ka mahlo a kelello likarolo tsa 'mele oa ka hare.Litlhahlobo tsa X-ray li ipakile e le tsa bohlokoa bakeng sa ho lemoha ho robeha ha masapo, ho khetholla lihlahala le ho batlisisa mafu a sa tšoaneng.Ho feta moo, theknoloji ea X-ray e fetohile ho kenyelletsa computed tomography (CT), fluoroscopy, le mammography, e ntse e atolosa bokhoni ba eona ba ho hlahloba.
Ho sa tsotellehe melemo e mengata ea li-tubes tsa X-ray, likotsi tse ka bang teng tse amanang le ho pepeseha ha mahlaseli li tlameha ho amoheloa.Litsebi tsa bongaka li koetlisetsoa ho leka-lekanya melemo ea litšoantšo tsa X-ray le likotsi tse ka bang teng tsa mahlaseli a feteletseng.Liprothokholo tse tiileng tsa ts'ireletso le tlhahlobo ea lethal dose ea radiation li netefatsa hore bakuli ba fumana tlhaiso-leseling e hlokahalang ha ba ntse ba fokotsa ho pepeseha ha mahlaseli.
Ka kakaretso,li-tubes tsa X-ray tsa bongakali fetotse litšoantšo tsa tlhahlobo ka ho lumella lingaka ho hlahloba tšebetso e ka hare ea 'mele oa motho ntle le mekhoa e hlaselang.Moqapi o rarahaneng oa tube ea X-ray e nang le cathode, anode le mokhoa oa ho pholisa o hlahisa litšoantšo tsa X-ray tsa boleng bo phahameng ho thusa ho hlahloba hantle.Ha theknoloji e ntse e tsoela pele, re ka lebella lintlafatso tse ling tsa litšoantšo tsa X-ray ho thusa bakuli le litsebi tsa tlhokomelo ea bophelo.
