Dab tsi yog rotating anode? Cov lus nug no feem ntau tshwm sim thaum tham txog cov txheej txheem ntawm X-ray raj. Hauv tsab xov xwm no, peb yuav delve tob rau hauv lub tswvyim ntawmrotating anode X-ray rajthiab tshawb nrhiav lawv qhov cuam tshuam hauv kev kho mob duab.
X-ray imaging tau hloov kho thaj chaw ntawm cov tshuaj los ntawm kev tso cai rau cov kws kho mob pom cov qauv sab hauv yam tsis muaj kev phais mob. X-ray raj yog nyob rau hauv lub plawv ntawm lub thev naus laus zis thiab tsim kom muaj lub zog X-rays uas yuav tsum tau ua rau cov txheej txheem tsis muaj kev cuam tshuam. Lub rotating anode yog ib qho tseem ceeb ntawm cov X-ray raj, ua rau lawv cov efficiency thiab ntev.
Yog li, dab tsi tiag tiag yog lub rotating anode? Yooj yim muab tso, nws yog lub hom phiaj zoo li lub hom phiaj ua los ntawm cov khoom siv atomic siab xws li tungsten lossis molybdenum. Lub hom phiaj rotates sai heev thaum lub sij hawm X-ray tiam, tso cai rau kom ntau npaum li cas kub dissipation thiab nce X-ray tso zis.
Lub hom phiaj tseem ceeb ntawm rotating anodes yog kom kov yeej cov kev txwv ntawm anodes ruaj. Nyob rau hauv cov pa tsau-anode X-ray raj, lub tshav kub tsim thaum lub sij hawm X-ray tiam yog txwv rau ib qho chaw me me ntawm anode. Qhov kub siab no ua kom nrawm nrawm rau lub anode, txwv lub zog thiab lub sijhawm ntawm X-ray tso zis. Rotating anodes daws qhov teeb meem no los ntawm kev nthuav tawm lub tshav kub ntawm thaj tsam loj, yog li txo qis anode hnav thiab txuas lub raj lub neej.
Kev tsim ntawm rotating anodes suav nrog complex engineering. Lub anode feem ntau yog ua los ntawm tungsten vim tias nws muaj lub siab melting point thiab tuaj yeem tiv taus cov cua sov uas tsim tawm thaum X-rays raug tsim. Tsis tas li ntawd, lub anode yog coated nrog nyias txheej ntawm refractory khoom, xws li graphite los yog molybdenum, los txhim kho nws thermal conductivity.
Kev sib hloov ntawm lub anode yog tiav nrog rotor thiab bearings. Lub rotor uas tau tsav los ntawm lub tshuab hluav taws xob tig lub anode ntawm kev kub ceev, feem ntau txog 3,000 txog 10,000 revolutions ib feeb. Cov kabmob ua kom muaj kev sib hloov du thiab ruaj khov, kev tsis sib xws lossis kev co tuaj yeem cuam tshuam cov duab zoo.
Qhov zoo ntawm rotating anode X-ray raj muaj ntau. Ua ntej, lub rotating anode muaj thaj tsam loj dua uas tuaj yeem ua kom sov tau zoo dua, yog li ncua sij hawm raug thiab nce X-ray tso zis. Qhov no txhais tau tias lub sijhawm kuaj luv dua thiab kev nplij siab ntawm tus neeg mob ntau dua. Tsis tas li ntawd, qhov ua haujlwm ntev ntawm qhov sib hloov anode tso cai rau lub raj X-ray tuaj yeem rov siv dua thiab siv sijhawm ntev, ua rau nws zoo tagnrho rau cov chaw kho mob siab.
Tsis tas li ntawd, lub peev xwm tsom mus rau X-ray beam mus rau thaj tsam me me ntawm cov anode ua rau kom muaj kev daws teeb meem thiab pom tseeb ntawm cov duab tshwm sim. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev kuaj pom, qhov pom tseeb ntawm cov qauv anatomical yog qhov tseem ceeb. Kev txhim kho cov cua sov dissipation peev xwm ntawm rotating anode pab txhawb cov duab txuas ntxiv yam tsis muaj kev cuam tshuam cua txias, ntxiv kev txhim kho kev ua haujlwm.
Hauv cov ntsiab lus,rotating anode X-ray raj revolutionized teb ntawm kev kho mob duab. Nrog lawv cov kev tsim kho qib siab thiab cov khoom siv hluav taws xob zoo tshaj plaws, cov raj no muaj ntau yam zoo dua li cov kav dej anode. Los ntawm cov khoom siv hluav taws xob ntau ntxiv thiab lub neej ntev lub raj kom txhim kho cov duab daws teeb meem, rotating anode X-ray raj tau dhau los ua cov cuab yeej tseem ceeb hauv kev kho mob niaj hnub no.
