Ho radiology, litšoantšo tse nepahetseng le polokeho ea mokuli li bohlokoa.Sesebelisoa sa bohlokoa se phethang karolo ea bohlokoa ho finyelleng lipakane tsena ke bukana ea X-ray collimator.Sengoliloeng sena se hlahloba tšebetso, melemo, le ts'ebeliso ea li-collimator tsa X-ray litšoantšong tsa bongaka.
Ithute ka li-collimator tsa X-ray:
A bukana ea X-ray collimatorke sesebelisoa se khomaretsoeng mochineng oa X-ray ho laola le ho ntlafatsa mahlaseli a mahlaseli.E na le letoto la li- shutter tsa loto tse etselitsoeng ho bōptjoa le ho lekanyetsa boholo le tsela ea leballo la X-ray.E thusa li-radiographer ho shebana hantle le libaka tse ikhethileng le ho netefatsa boleng bo nepahetseng ba setšoantšo ha li ntse li fokotsa ho pepeseha ho sa hlokahaleng ha mahlaseli.
Melemo ea li-collimator tsa X-ray:
Tšireletseho ea mahlaseli: Li-collimator tsa X-ray tse Manual li thusa ho fokotsa litekanyetso tsa mahlaseli ho bakuli le litsebi tsa tlhokomelo ea bophelo.Ka ho fokotsa mahlaseli a X-ray, li-collimator li fokotsa ho pepeseha ha lisele tse phetseng hantle ho potoloha sebaka seo ho shebiloeng ho sona, kahoo li fokotsa likotsi tse ka bang teng tsa mahlaseli.
Boleng ba setšoantšo: Li-collimator tse entsoeng ka letsoho li ntlafatsa ho hlaka le lintlha tse qaqileng tsa setšoantšo ka ho bopa hantle le ho tsepamisa mohopolo oa X-ray.Boleng bo ntlafetseng ba setšoantšo bo thusa ho hlahloba hantle le ho fokotsa tlhokahalo ea ho pheta-pheta lithuto tsa litšoantšo, ho boloka nako le lisebelisoa.
Matšeliso a mokuli: Li-collimator li netefatsa hore mahlaseli a lebisitsoe hantle sebakeng se reriloeng, ho qoba ho pepeseha ho sa hlokahaleng likarolong tse ling tsa 'mele.Sena se ntlafatsa haholo matšeliso a mokuli nakong ea ho nka litšoantšo.
Katleho ea Litšenyehelo: Li-X-ray collimator tse entsoeng ka letsoho li thusa mekhatlo ea tlhokomelo ea bophelo le bafani ba inshorense ho boloka litšenyehelo ka ho ntlafatsa boleng ba setšoantšo le ho fokotsa tlhoko ea ho pheta-pheta litlhahlobo.
Lisebelisoa tsa li-collimator tsa X-ray:
Radiology ea ho hlahloba: Li-collimator tse sebelisoang ka letsoho li sebelisoa haholo mekhoeng e mengata ea ho hlahloba mafu, ho akarelletsa X-ray, computed tomography (CT), le angiography.Ba thusa li-radiographer ho fihlela litšoantšo tse nepahetseng tsa libaka tse itseng tsa anatomical, kahoo li ntlafatsa ho nepahala ha tlhahlobo.
Kalafo ea radiation: Li-collimator tse etsoang ka letsoho li bapala karolo ea bohlokoa kalafong ea radiation, moo lehlaseli la radiation le lokelang ho tsepamisoa hantle sebakeng sa hlahala ha le ntse le fokotsa tšenyo ea lisele tse phetseng hantle.Li thusa ho netefatsa phano e lebisitsoeng ea litekanyetso tsa kalafo, ho ntlafatsa katleho ea kalafo.
Ho buuoa ka nakoana: Li-collimator tse tsamaisoang ka letsoho li thusa ho tataisa li-catheter le lisebelisoa tse ling nakong ea ts'ebetso e fokolang haholo.Ka ho tsamaisa mahlaseli a X-ray hantle, li-collimator li nolofalletsa pono ea nako ea sebele, ho ntlafatsa polokeho le katleho ea mehato ena.
Tsoelopele le tsoelopele ea nakong e tlang:
Likarolo tse itirisang: Li-collimator tse entsoeng ka letsoho li bile teng ka tsoelo-pele ea theknoloji ho kenyelletsa likarolo tse itirisang tse joalo ka boholo ba beam, angle ea beam, le tlhahlobo ea nako ea nnete.
Taolo e hole: Lintlafatso tsa nako e tlang li ka kenyelletsa matla a taolo a hole a lumellang li-radiographer ho fetola litlhophiso tsa collimator ntle le ho ba haufi le mochini oa X-ray, e leng ho eketsang boiketlo ba basebelisi le polokeho.
Mehato e meng ea ts'ireletso: Ho kopanya mehato e meng ea ts'ireletso, joalo ka li-sensor tsa mahlaseli a kotsi le li-algorithms tsa ntlafatso ea lethal dose, ho ka thusa ho fokotsa likotsi tsa mahlaseli nakong ea ho nka litšoantšo.
Ka kakaretso:
Li-collimator tsa X-ray ka letsohoke lisebelisoa tsa bohlokoa ho radiology mme li bapala karolo ea bohlokoa ho ntlafatseng sephetho sa litšoantšo le polokeho ea mokuli.Ka ho fokotsa lethal dose ea mahlaseli, ho ntlafatsa boleng ba setšoantšo, le ho ntlafatsa boiketlo ba mokuli, li-collimator tse entsoeng ka letsoho li fetohile karolo ea bohlokoa ea mefuta e fapaneng ea likopo tsa litšoantšo tsa bongaka.Tsoelo-pele e tsoelang pele ea theknoloji ea collimator ntle le pelaelo e tla ntlafatsa ho nepahala ha litšoantšo le ho khothaletsa tsoelo-pele e akaretsang ea tlhahlobo le kalafo ea mahlaseli.
