iteknoloji enkulu | Ishishini elitsha | Epreli 29.2025
Ngophuhliso olukhawulezileyo lwetekhnoloji yokuxilonga yezonyango, i-computed tomography (CT) iye yaba yindlela ebalulekileyo neyimfuneko yokuxilonga ngokwezonyango. Umfanekiso we-CT ocacileyo nochanekileyo awunakubonelela oogqirha ngesiseko esibalulekileyo sokuxilonga, kodwa uchaphazela ngokuthe ngqo ukuxilongwa kunye nesiphumo sonyango lwezigulane. Emva kokusebenza kakuhle kwezixhobo ze-CT, i-CT slip ring, njengenxalenye ephambili, idlala indima engenakutshintshwa ngokuthe cwaka. Ukusebenza kwayo kuchaphazela ngokuthe ngqo umgangatho womfanekiso, isantya sokuskena kunye nozinzo lwezixhobo ze-CT, kwaye inokubizwa ngokuba "liziko lamandla kunye nesignali" yezixhobo ze-CT.
Ⅰ. Yintoni iringi ye-CT slip?
I-CT slip ring ngokuyintloko yiringi yokutyibiliza eyenzelwe ngokukodwa, eyenzelwe ngokukodwa iimfuno zokuskena ukujikeleza kwezixhobo ze-CT zonyango. Izixhobo ze-CT zemveli zisebenzisa iintambo ukudibanisa inxalenye ejikelezayo kunye nenxalenye emileyo. Njengoko izixhobo zisebenza ixesha elide, iintambo zinokubanjwa, ziguge okanye ziqhekeke, nto leyo engachaphazeli nje kuphela ukusetyenziswa okuqhelekileyo kwezixhobo, kodwa ikwabeka nobungozi kukhuseleko. Ukuvela kweeringi zokutyibiliza ze-CT kuyisombulula ngokupheleleyo le ngxaki. Ifezekisa ukuhanjiswa okungaphazanyiswa kwamandla kunye nemiqondiso yedatha ngexesha lokujikeleza okuqhubekayo kwezixhobo ze-CT ngama-degree angama-360 ngokunxibelelana okutyibilikayo phakathi kwebrashi kunye neringi yokutyibiliza.
Ngokwembono yesakhiwo, iringi ye-CT slip yenziwe kakhulu yi-rotor, i-stator, ibrashi, iringi yokuqhuba kunye ne-casing. Inxalenye ye-rotor iqhagamshelwe kwisakhelo esijikelezayo sesixhobo se-CT, kwaye i-stator inamathele kwisakhelo esimileyo sesixhobo. Ibrashi yenziwe ngezinto ezikhethekileyo ezinokuqhuba okuphezulu kunye nokumelana nokuguguleka okuphezulu, kwaye ihambelana ngokuqinileyo neringi yokuqhuba. Xa isixhobo se-CT siskena, i-rotor iqhuba ibrashi ukuba ityibilike phezu komphezulu weringi yokuqhuba, kwaye imiqondiso yangoku kunye nedatha idluliselwa ukusuka kwisiphelo se-stator ukuya kwisiphelo se-rotor, ukuqinisekisa ukusebenza okuqhubekayo nokuzinzileyo kwezixhobo eziphambili zesixhobo se-CT, ezifana netyhubhu kunye ne-detector.
