Tig Cathode x-ray mives (rotating anode xoo hluav taws xob) yog lub siab-precision x-ray qhov chaw rau kev kho mob thiab kev ua haujlwm. Raws li nws lub npe qhia, nws muaj ntawm kev tig cathode thiab yog ib qho ntawm cov khoom tseem ceeb ntawm x-ray khoom.
Ib co rothod rajle X-eamooth raj muaj ntawm cathode, ib qho anode, ib lub rotor thiab cov stator. Tus Cathode yog tus pas hlau hlau uas emits cov khoom hluav taws xob thermoelcrically, thiab anode yog rov qab rau nws thiab rotates ib puag ncig nws. Lub anode yog ua los ntawm siab thermal conductivity cov khoom siv thiab muaj dej raws rau cua txias. Lub anode feem ntau yog ua los ntawm cov hlau refractory xws li tungsten, molybdenum, uas yog tiv thaiv cua sov thiab hluav taws xob puas tsuaj los ntawm lub zog hluav taws xob.
Thaum lub electron nqaj ntaus saum npoo ntawm cathode, cov tshuab hluav taws xob yog rhaub thiab tso tawm. Cov tshuab hluav taws xob no tau nrawm rau lub anode, qhov chaw uas lawv tau decelerated thiab tawg, ua kev siv hluav taws xob ntau x-tshav. Lub rotating oney faib cov cua sov rau tag nrho anode nto, thiab txias nws los ntawm cov dej channel kom ntseeg tau tias qhov kev ruaj khov thiab kev ntseeg tau ntawm kev siv ntev.
Tig Cathode X-ray raj muaj ntau qhov zoo, suav nrog lub zog hluav taws xob muaj zog, siab rau-suab nrov sib piv, muaj peev xwm hloov kho rau ntau yam kev yees duab, thiab lub neej ntev. Yog li ntawd, nws yog qhov xhoo tshav ntawm kev xaiv hauv liaj teb xws li kev kho mob kev yees duab, kev lag luam CT txiav kom pom tseeb, thiab kev sim ua tsis yog kev ua kom tsis txhob ua kom tsis txhob muaj kev puas tsuaj.
Hauv cov ntsiab lus, ib lub raj raj nplaim hluav taws xob yog lub siab-ua kom pom X-ray thiab txhim khu kev daws teeb meem X-Rooth thiab txhim khu ntau hom sib txawv ntawm cov ntawv thov.
