Rotating cathode X-ray tubes (Rotating Anode X-Ray Tubes) yog cov khoom siv hluav taws xob zoo tshaj plaws rau kev kho mob thiab kev lag luam. Raws li nws lub npe qhia, nws muaj cov cathode rotating thiab yog ib qho tseem ceeb ntawm cov khoom siv X-ray.
Lub rotating cathode X-ray raj muaj cathode, anode, rotor thiab stator. Lub cathode yog ib tug hlau pas nrig uas emits electrons thermoelectrically, thiab lub anode yog opposite rau nws thiab rotates nyob ib ncig ntawm nws. Lub anode yog ua los ntawm cov khoom siv thermal conductivity siab thiab muaj cov kav dej kom txias. Lub anode feem ntau yog ua los ntawm cov hlau refractory xws li tungsten, molybdenum, lossis platinum, uas tiv taus cua sov thiab hluav taws xob puas tsuaj los ntawm lub zog X-rays.
Thaum lub teeb hluav taws xob tsoo rau saum npoo ntawm cathode, cov electrons raug cua sov thiab tso tawm. Cov electrons no tau nrawm rau ntawm lub anode, qhov chaw uas lawv tau qeeb thiab tawg, ua kom muaj zog X-ray hluav taws xob. Lub rotating anode tusyees faib cov hluav taws xob generated rau tag nrho cov anode nto, thiab txias nws los ntawm cov dej channel los xyuas kom meej stability thiab kev cia siab ntawm kev siv mus sij hawm ntev.
Rotating cathode X-ray raj muaj ntau qhov zoo, suav nrog lub zog siab, siab siv hluav taws xob X-ray hluav taws xob, siab tsom rau tam sim no, siab teeb liab-rau-nruj piv, muaj peev xwm hloov kho rau ntau yam kev xav tau, thiab lub neej ua haujlwm ntev. Yog li ntawd, nws yog qhov kev xaiv X-ray hauv thaj chaw xws li kev kuaj mob, kuaj CT qhov tsis txaus ntseeg, thiab kuaj tsis muaj kev puas tsuaj.
Nyob rau hauv cov ntsiab lus, ib tug rotating cathode X-ray raj yog ib tug high-power, ruaj khov thiab txhim khu kev qha X-ray qhov chaw uas muab qhov tseeb, high-zoo thiab high-resolution X-ray dluab rau ntau yam sib txawv ntawm daim ntawv sau npe.
