X-ray tshuab tau dhau los ua cov cuab yeej tseem ceeb hauv kev lag luam kev ruaj ntseg. Kev ruaj ntseg X-ray tshuab muab txoj hauv kev tsis muaj kev cuam tshuam los tshawb xyuas cov khoom zais lossis cov khoom phom sij hauv lub nra, pob khoom thiab ntim khoom. Hauv plawv ntawm lub tshuab x-ray kev ruaj ntseg yog lub raj x-ray, uas ua rau lub zog loj x-rays siv hauv kev luam.
X-ray tubesyog siv nyob rau hauv ntau yam kev siv nyob rau hauv radiography, kho mob imaging, ntaub ntawv science, thiab industrial tsom xam. Txawm li cas los xij, hauv kev lag luam kev ruaj ntseg, X-ray raj ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb rau pej xeem, tiv thaiv kev ua phem thiab txhim kho kev nyab xeeb.
An X-ray tubeyog ib qho khoom siv hluav taws xob uas hloov hluav taws xob hluav taws xob mus rau lub zog hluav taws xob X-rays rau kev yees duab. Lub raj muaj lub cathode thiab ib qho anode nyob rau hauv lub tshuab nqus tsev chamber. Thaum tam sim no dhau los ntawm cathode, nws tso tawm cov kwj ntawm electrons, uas yog nrawm rau lub anode. Cov hluav taws xob sib tsoo nrog cov anode, tsim cov X-rays uas tau qhia ntawm cov khoom raug tshuaj xyuas.
Kev ruaj ntseg X-ray tshuab siv ob hom X-ray raj: hlau ceramic (MC) raj thiabrotating anode (RA) raj. MC raj feem ntau siv vim nws yog tus nqi qis, ruaj khov thiab txhim khu kev qha. Nws tsim ib qho chaw ruaj khov, tsis tshua muaj hluav taws xob xoo hluav taws xob zoo tagnrho rau cov khoom siv ntawm cov khoom siv tsawg. Ntawm qhov tod tes, RA tubes muaj zog dua MC cov raj thiab tsim cov kab hluav taws xob ntau dua. Tsim nyog rau kev soj ntsuam cov khoom siv nrog cov khoom siv ntom ntom xws li hlau.
Kev ua haujlwm ntawm lub raj xa hluav taws xob hauv lub tshuab X-ray muaj kev nyab xeeb yog cuam tshuam los ntawm ntau yam, suav nrog lub raj hluav taws xob, lub raj tam sim no, thiab lub sijhawm raug. Lub raj hluav taws xob txiav txim siab lub zog ntawm X-rays generated, thaum lub raj tam sim no tswj tus nqi ntawm X-rays generated ib lub sij hawm. Lub sij hawm raug txiav txim siab lub sijhawm ntawm X-rays qhia ntawm qhov khoom raug tshuaj xyuas.
Qee lub tshuab X-ray kev ruaj ntseg siv dual-zog X-ray duab thev naus laus zis, uas siv ob lub X-ray raj nrog ntau lub zog sib txawv. Ib lub raj tsim hluav taws xob xoo hluav taws xob tsawg, thaum lwm qhov tsim hluav taws xob X-rays. Cov duab tshwm sim qhia cov xim sib txawv uas qhia txog qhov ntom ntom thiab atomic naj npawb ntawm txhua yam khoom hauv daim duab scanned. Cov thev naus laus zis tso cai rau cov neeg ua haujlwm sib txawv ntawm cov khoom siv organic thiab inorganic, txhim kho kev tshawb pom ntawm cov khoom zais.
Hauv cov ntsiab lus, X-ray raj yog cov pob txha ntawm lub tshuab X-ray kev ruaj ntseg, pab txheeb xyuas cov khoom zais, cov khoom tawg, thiab cov khoom siv phom sij. Lawv muab txoj hauv kev nrawm, ua haujlwm tau zoo thiab tsis muaj kev cuam tshuam rau kev txheeb xyuas lub nra, pob khoom thiab ntim khoom. Yog tsis muaj X-ray raj, kev soj ntsuam kev ruaj ntseg yuav yog ib qho nyuaj thiab siv sij hawm, ua kom muaj kev nyab xeeb rau pej xeem thiab tiv thaiv kev ua phem ua phem. Yog li ntawd, txoj kev loj hlob ntawm X-ray raj tshuab tseem tseem ceeb heev rau yav tom ntej ntawm kev ruaj ntseg X-ray tshuab.
