Phekolo ea Proton

Phekolo ea Proton ke mofuta oa radiation e sebelisoang ho alafa mofetše. Joalo ka mefuta e meng ea radiation, kalafo ea proton e bolaea lisele tsa mofetše mme ea li emisa hore li se ke tsa hola.

Ho fapana le mefuta e meng ea kalafo ea radiation e sebelisang x-ray ho senya lisele tsa mofets'e, kalafo ea proton e sebelisa molamu oa likaroloana tse khethehileng tse bitsoang proton. Lingaka li ka shebella lipalone tsa proton hantle holima hlahala, ka hona ho na le tšenyo e nyane ho lisele tse haufi tse phetseng hantle. Sena se lumella lingaka ho sebelisa lethal dose e phahameng ea radiation le proton therapy ho feta kamoo ba ka sebelisang le x-ray.

Phekolo ea Proton e sebelisetsoa ho alafa mofetše o sa jalang. Hobane e baka tšenyo e nyane ho lisele tse phetseng hantle, kalafo ea proton e sebelisoa khafetsa bakeng sa mofetše o haufi haholo le likarolo tsa bohlokoahali tsa 'mele.

Lingaka li ka sebelisa kalafo ea proton ho alafa mefuta e latelang ea mofets'e:

• Bokooa (acoustic neuroma, lihlahala tsa bongoana bongoaneng)
• Leihlo (ocular melanoma, retinoblastoma)
• Hlooho le molala
• Lung
• Mokokotlo (chordoma, chondrosarcoma)
• Tšoelesa ea senya
• Kankere ea Lymph system

Bafuputsi ba ntse ba ithuta hore na kalafo ea proton e ka sebelisoa ho phekola maemo a mang a sa cheseheng, ho kenyelletsa le ho senyeha ha macular.

MOKHOA OA HO SEBETSA

Mofani oa hao oa tlhokomelo ea bophelo o tla u lekana le sesebelisoa se khethehileng se ts'oereng 'mele oa hau nakong ea kalafo. Sesebelisoa sa 'nete se sebelisitsoeng se latela sebaka sa mofetše oa hau. Mohlala, batho ba nang le mofetše oa hlooho ba kanna ba etsetsoa mask e khethehileng.

Ka mor'a moo, o tla ba le scan ea computed tomography (CT) kapa ea magnetic resonance imaging (MRI) ho etsa 'mapa oa sebaka se lokelang ho phekoloa. Nakong ea scan, u tla apara sesebelisoa se u thusang ho khutsa. Ngaka ea mahlaseli ea mahlaseli e tla sebelisa k'homphieutha ho fumana hlahala le ho hlahisa li-angles moo lipallo tsa proton li tla kena 'meleng oa hau.

Phekolo ea Proton e etsoa ka ntle ho mokuli. Kalafo e nka metsotso e seng mekae ka letsatsi nakong ea libeke tse 6 ho isa ho tse 7, ho latela mofuta oa mofets'e. Pele kalafo e qala, o tla kena sesebelisoa se tla u ts'oara. Setsebi sa radiation se tla nka li-x-ray tse 'maloa ho lekola kalafo hantle.

U tla beoa kahare ho sesebelisoa se bopehileng joaloka donut se bitsoang gantry. E tla potoloha haufi le uena mme e supise liprotheine tseleng ea hlahala. Mochini o bitsoang synchrotron kapa cyclotron o theha le ho potlakisa proton. Ebe liprotheine li tlosoa mochineng 'me limakete li li lebisa hlahala.

Setsebi se tla tsoa ka phapusing ha o ntse o fumana kalafo ea proton. Kalafo e lokela ho nka metsotso e 1 ho isa ho e 2 feela. Ha ua lokela ho ikutloa u sa phutholoha. Kamora hore kalafo e fele, setsebi se tla khutlela ka phapusing ebe se u thusa ho tlosa sesebelisoa se neng se u ts'oere.

LIEKETSO NTHAKO

Phekolo ea Proton e kanna ea ba le litlamorao, empa tsena li ba bonolo ho feta mahlaseli a X-ray hobane kalafo ea proton e baka tšenyo e nyane ho lisele tse phetseng hantle. Litla-morao li ipapisitse le sebaka se alafshoang, empa li ka kenyelletsa bofubelu ba letlalo le tahlehelo ea moriri oa nakoana sebakeng sa radiation.

KA MOR'A TSAMAISO

Kamora kalafo ea proton, o lokela ho qala mesebetsi ea hau e tloaelehileng. U kanna oa bona ngaka ea hau likhoeling tse ling le tse ling tse 3 ho isa ho tse 4 bakeng sa tlhahlobo e latelang.
