Li-collimator tsa X-ray tsa bongakali bapala karolo ea bohlokoa ho hlahlobeng litšoantšo, ho netefatsa hore mahlaseli a nepahetseng a lebisitsoe ho tsona le ho fokotsa ho pepesehela mahlaseli ho sa hlokahaleng. Ka tsoelo-pele e tsoelang pele theknolojing, litsebi tsa bongaka joale li rua molemo likarolong tsa morao-rao tse etselitsoeng ho eketsa ho nepahala le polokeho ea mokuli. Sengoloa sena se hlahloba tsoelo-pele ea bohlokoa ho li-collimator tsa X-ray tsa bongaka, se totobatsa bohlokoa ba tsona ho radiology.
Collimation e fetolehang
E 'ngoe ea tsoelo-pele ea bohlokoa ka ho fetisisa ho li-collimator tsa X-ray tsa bongaka ke bokhoni ba ho fetola boholo ba collimation. Li-collimator tsa setso li hloka phetoho ea letsoho 'me li na le bokhoni bo fokolang ba ho fana ka tatellano e nepahetseng le e etselitsoeng motho ka mong. Li-collimator tsa sejoale-joale li fana ka likhetho tsa taolo ea enjene kapa ea letsoho, e lumellang litsebi tsa mahlaseli ho fetola litekanyo tsa collimation habonolo. Tšobotsi ena e lumella ho beha hantle mahlaseli a X-ray, ho netefatsa hore ke sebaka se lakatsehang feela se bonesoang. Ka ho fokotsa mahlaseli a hasaneng, collimation e fetoloang e nolofalletsa ho nka litšoantšo ka nepo haholoanyane, ho fokotsa ho pepesehela mokuli le ho ntlafatsa boleng ba setšoantšo ka kakaretso.
Meeli ea ho bokellana
Ho thibela ho pepesehela mahlaseli ka phoso, li-collimator tsa sejoale-joale tsa X-ray li na le likarolo tse fokotsang collimation. Tšobotsi ena e netefatsa hore tšimo ea X-ray e lekanyelitsoe ho boholo bo behiloeng esale pele, e thibela ho pepesehela libaka tse haufi ka phoso. Meeli ea collimation e ntlafatsa polokeho ea mokuli ka ho fokotsa ho pepesehela mahlaseli a sa hlokahaleng le ho fokotsa kotsi ea litla-morao tse ka bang teng tse amanang le tekanyo e feteletseng ea mahlaseli.
Sistimi ea ho hokahanya le laser
Ho ntlafatsa ho nepahala ha sebaka seo mokuli a leng ho sona, li-collimator tsa sejoale-joale tsa X-ray li sebelisa litsamaiso tsa ho hokahanya le laser. Litsamaiso tsena li hlahisa mela e bonahalang ea laser 'meleng oa mokuli, li bontša libaka tse tobileng tse pepesetsoeng mahlaseli. Ho hokahanya le laser ho fana ka tataiso e bonahalang bakeng sa sebaka se nepahetseng, ho fokotsa kotsi ea ho se lumellane hantle le ho fokotsa tlhoko ea ho pepesehela mokuli khafetsa. Tsoelo-pele ena e ntlafatsa boiketlo ba mokuli 'me e nolofatsa ts'ebetso ea ho nka litšoantšo, haholo-holo ha ho etsoa opereishene e rarahaneng.
Ho tsepamisa mohopolo ka boiketsetso ho collimator
Ho beha collimator bohareng ba detector ea X-ray ho bohlokoa bakeng sa ho nka litšoantšo hantle. Ho beha bohareng ba collimator ka boiketsetso ho nolofatsa ts'ebetso ena mme ho felisa tlhoko ea liphetoho tsa letsoho. Tšobotsi ena e sebelisa li-sensor ho lemoha boemo ba detector ea X-ray le ho beha bohareng ba collimator ka boiketsetso ho latela maemo. Ho beha bohareng ba collimator ka boiketsetso ho fokotsa liphoso tsa batho, ho netefatsa ho lumellana hantle le ho eketsa katleho ea mosebetsi oa hau oa ho nka litšoantšo.
Tlhokomelo le taolo ea tekanyo
Polokeho ea mokuli ke ea bohlokoa haholo litšoantšong tsa bongaka. Li-collimator tsa sejoale-joale tsa X-ray li kenyelletsa tlhokomelo ea tekanyo le likarolo tsa taolo ho thusa ho ntlafatsa ho pepesehela mahlaseli. Likarolo tsena li lumella basebelisi ho beha leihlo le ho fetola boleng ba tekanyo ea mahlaseli ho latela litšobotsi tsa mokuli tse kang lilemo, boima le litlhoko tsa tlhahlobo. Ka ho etsa hore ho pepesehela mahlaseli ho lumellane le bakuli ka bomong, tlhokomelo ea tekanyo le bokhoni ba taolo bo fokotsa mahlaseli a sa hlokahaleng le ho fokotsa likotsi tse ka bang teng tse amanang le ho pepesehela mahlaseli a mangata.
ha re phethela
Tsoelo-pele holi-collimator tsa X-ray tsa bongakali fetotse lefapha la radiology, li ntlafatsa ho nepahala le ho ntlafatsa polokeho ea mokuli. Collimation e fetoloang, meeli ea collimation, litsamaiso tsa ho hokahanya laser, ho tsepamisa mohopolo oa collimator ka boiketsetso, le likarolo tsa tlhokomelo le taolo ea tekanyo li ntlafatsa haholo ho nepahala le katleho ea mekhoa ea ho etsa litšoantšo tsa tlhahlobo. Lintho tsena tse ncha li nolofalletsa litsebi tsa radiology ho fumana litšoantšo tsa boleng bo holimo ha li ntse li fokotsa ho pepesehela mahlaseli a mokuli. Ha theknoloji e ntse e tsoela pele ho fetoha, litsebi tsa bongaka li ka lebella tsoelo-pele e eketsehileng ho li-collimator tsa X-ray, ho netefatsa ntlafatso e tsoelang pele ho nepahala ha tlhahlobo le boiketlo ba mokuli.
