Lefapheng la bongaka ba sejoale-joale, ho etsa litšoantšo tsa tlhahlobo ho phetha karolo ea bohlokoa tlhokomelong ea bakuli, ho lumella litsebi tsa tlhokomelo ea bophelo ho bona ka mahlo a kelello libopeho tsa ka hare tsa 'mele. Har'a mekhoa e fapaneng ea ho etsa litšoantšo, ho etsa litšoantšo tsa X-ray e ntse e le e 'ngoe ea mekhoa e sebelisoang haholo. Motheong oa theknoloji ena ke tube ea X-ray ea bongaka, sesebelisoa se fetotseng tsela eo re hlahlobang le ho phekola maemo a bongaka ka eona.
Chupu ea X-ray ea bongaka ke eng?
A tube ea X-ray ea bongakake tube e khethehileng ea vacuum e hlahisang mahlaseli a X ka ho sebelisana ha lielektrone tse nang le matla a mangata le thepa e reretsoeng, hangata e entsoeng ka tungsten. Ha motlakase o sebelisoa, lielektrone li ntšoa ho tsoa cathode e futhumetseng ebe li potlakisoa ho ea ho anode. Kamora ho otla anode, lielektrone tsena tse lebelo le phahameng li thulana le thepa e reretsoeng, li hlahisa mahlaseli a X nakong eo. Mokhoa ona oa motheo o re lumella ho hapa litšoantšo tsa masapo, litho le lisele tse ka hare ho 'mele oa motho.
Likarolo tsa Liphaephe tsa X-Ray
Ho utloisisa likarolo tsa tube ea X-ray ea bongaka ho bohlokoa haholo ho utloisisa mosebetsi oa eona. Likarolo tse ka sehloohong li kenyelletsa:
- Cathode: Karolo ena e na le khoele e futhumatsoang ho hlahisa lielektrone. Cathode e bohlokoa haholo ho qaleng ts'ebetso ea tlhahiso ea X-ray.
- Anode: Anode e sebetsa e le sepheo sa hore cathode e ntše lielektrone. Hangata e entsoe ka tungsten ka lebaka la ntlha ea eona e phahameng ea ho qhibiliha le bokhoni ba eona ba ho hlahisa mahlaseli a X.
- Enfelopo ea khalase kapa ea tšepe: Kopano eohle e ka har'a enfelopo e koetsoeng ka vacuum, e thibelang lielektrone ho thulana le limolek'hule tsa moea le ho netefatsa tlhahiso e sebetsang ea X-ray.
- Ho sefa: Ho ntlafatsa boleng ba setšoantšo le ho fokotsa ho pepesehela mokuli mahlaseli a sa hlokahaleng, ho sebelisoa li-filter ho tlosa mahlaseli a X a matla a fokolang a sa kenyeng tlhahisoleseling ea tlhahlobo.
- Collimator: Sesebelisoa sena se bopa le ho fokotsa mahlaseli a X-ray, se netefatsa hore ke libaka tse hlokahalang feela tse pepesehang nakong ea ho nka litšoantšo.
Bohlokoa ba Lipeipi tsa X-Ray ho Tlhokomelo ea Bophelo
Li-tube tsa X-ray tsa bongaka li bohlokoa haholo maemong a fapaneng a bongaka. Li na le mefuta e mengata ea lits'ebetso ho kenyeletsoa:
- Tlhahlobo ea ho robeha ha lehare: Li-X-ray ke mola oa pele oa litšoantšo bakeng sa ho robeha ho belaelloang 'me li ka hlahloba tšenyo ea masapo kapele le ka nepo.
- Ho lemoha hlahala: Litšoantšo tsa X-ray li ka thusa ho khetholla kholo e sa tloaelehang kapa lihlahala, e leng se tataisang mekhoa e meng ea ho hlahloba.
- Litšoantšo tsa meno: Kalafong ea meno, lipeipi tsa X-ray li sebelisoa ho hapa litšoantšo tsa meno le meaho e potolohileng ho thusa ho fumana mathata a meno.
- Setšoantšo sa sefuba: Hangata li-X-ray tsa sefuba li sebelisoa ho hlahloba boemo ba matšoafo, boholo ba pelo, le mathata a mang a sefuba.
Tsoelo-pele Theknolojing ea X-Ray Tube
Lefapha la ho nka ditshwantsho tsa bongaka le ntse le tswela pele ho fetoha, mme le theknoloji e amanang le di-tube tsa X-ray e ntse e fetoha. Dintlafatso tsa moraorao di kenyeletsa ntshetsopele ya ditsamaiso tsa dijithale tsa X-ray tse ntlafatsang boleng ba setshwantsho, tse fokotsang ho pepesehela mahlaseli a kotsi, le ho kgutsufatsa dinako tsa tshebetso. Ho phaella moo, mahlale a matjha a kang mechine ya X-ray e nkehang habobebe a etsa hore ho nka ditshwantsho ho kgonehe maemong a fapaneng, ho kenyeletswa le diphaposi tsa maemo a tshohanyetso le dibakeng tse hole.
ha re phethela
Liphaephe tsa X-ray tsa bongakake karolo ea bohlokoa ea ho etsa litšoantšo tsa tlhahlobo, ho fa litsebi tsa tlhokomelo ea bophelo lisebelisoa tseo li li hlokang ho etsa liqeto tse nang le tsebo mabapi le tlhokomelo ea bakuli. Ha theknoloji e ntse e tsoela pele ho hatela pele, bokhoni ba lipeipi tsa X-ray bo tla tsoela pele ho ntlafala, e leng se fellang ka ho nepahala ho hoholo ha tlhahlobo le liphello tse ntlafetseng tsa bakuli. Ho utloisisa mosebetsi le bohlokoa ba lisebelisoa tsena ho bohlokoa ho mang kapa mang ea nang le thahasello lefapheng la bongaka, kaha li emela lejoe la motheo la mokhoa oa sejoale-joale oa tlhahlobo. Ebang ke lipetlele, litleliniking kapa liofising tsa meno, lipeipi tsa X-ray tsa bongaka li tla lula e le karolo ea bohlokoa ea tlhokomelo ea bophelo lilemong tse tlang.
