X-ray tube sib dhosyog ib feem tseem ceeb ntawm kev kho mob thiab kev lag luam X-ray tshuab. Nws yog lub luag haujlwm rau kev tsim cov kab hluav taws xob X-ray uas xav tau rau kev siv duab lossis kev lag luam. Lub rooj sib txoos yog tsim los ntawm ntau yam sib txawv uas ua haujlwm ua ke kom muaj kev nyab xeeb thiab ua tau zoo tsim cov kab hluav taws xob X-ray.
Thawj feem ntawm X-ray raj sib dhos yog lub cathode. Lub cathode yog lub luag haujlwm rau kev tsim cov ndlwg ntawm electrons uas yuav siv los tsim X-rays. Lub cathode feem ntau yog ua los ntawm tungsten lossis lwm hom hlau refractory. Thaum lub cathode yog rhuab, electrons yog emissions los ntawm nws nto, tsim ib tug khiav ntawm electrons.
Qhov thib ob ntawm X-ray raj sib dhos yog lub anode. Lub anode yog tsim los ntawm cov khoom siv uas tuaj yeem tiv taus cov cua kub ntau thaum lub sijhawm X-ray tiam. Anodes feem ntau yog ua los ntawm tungsten, molybdenum lossis lwm yam hlau zoo sib xws. Thaum electrons los ntawm cathode tsoo lub anode, lawv tsim X-rays.
Qhov thib peb ntawm X-ray raj sib dhos yog lub qhov rais. Lub qhov rais yog ib txheej nyias ntawm cov khoom uas tso cai rau X-rays dhau los. Nws tso cai rau cov X-rays uas tsim los ntawm lub anode kom dhau los ntawm X-ray raj thiab mus rau hauv cov khoom raug duab. Lub qhov rais feem ntau yog ua los ntawm beryllium los yog lwm yam khoom uas yog pob tshab rau x-rays thiab muaj peev xwm tiv taus cov kev ntxhov siab ntawm x-ray ntau lawm.
Qhov thib plaub ntawm X-ray raj sib dhos yog lub tshuab ua kom txias. Txij li cov txheej txheem X-ray tsim cov cua sov ntau, nws yog ib qho tseem ceeb uas yuav tsum tau muab cov X-ray raj sib dhos nrog cov cua txias kom tsis txhob muaj cua sov. Lub tshuab ua kom txias muaj cov kiv cua lossis cov khoom siv hluav taws xob uas ua rau cov cua sov uas tsim los ntawm X-ray raj thiab tiv thaiv kev puas tsuaj rau cov khoom.
Qhov kawg ntawm X-ray raj sib dhos yog cov qauv kev txhawb nqa. Cov qauv kev txhawb nqa yog lub luag haujlwm tuav tag nrho lwm qhov ntawm X-ray raj sib dhos rau hauv qhov chaw. Nws feem ntau yog ua los ntawm cov hlau thiab tsim los tiv thaiv lub zog tsim thaum lub sijhawm X-ray tsim.
Hauv cov ntsiab lus, ibX-ray tube sib dhosyog ib pawg complex ntawm cov khoom uas ua hauj lwm ua ke kom muaj kev nyab xeeb thiab ua tau zoo tsim lub X-ray beam. Txhua feem ntawm X-ray tube sib dhos ua lub luag haujlwm tseem ceeb hauv kev tsim cov X-rays, thiab txhua yam tsis ua haujlwm lossis ua haujlwm tsis zoo hauv cov khoom yuav ua rau muaj kev puas tsuaj loj rau lub cev lossis ua rau muaj kev pheej hmoo rau cov neeg siv ntawm X-ray system. Yog li ntawd, kev saib xyuas kom zoo thiab kev tshuaj xyuas tsis tu ncua ntawm X-ray tube Cheebtsam yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm X-ray system.
