Taw qhia:
X-ray tshuab tau siv dav hauv ntau qhov chaw, suav nrog tshuaj, kev lag luam, thiab kev tshawb fawb, rau lawv lub peev xwm los tsim cov duab ntxaws ntawm cov qauv sab hauv. Nyob rau hauv lub plawv ntawm lub tshuab X-ray yog lub X-ray raj, ib qho tseem ceeb ntawm lub luag hauj lwm rau tsim X-rays. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov haujlwm thiab kev sib koom tes ntawm X-ray raj hauv X-ray tshuab.
Kev ua haujlwm ntawm X-ray Tube:
X-ray raj yog tsim los tsim cov kab hluav taws xob tswj thiab tsom ntawm X-rays, uas tuaj yeem dhau los ntawm cov khoom thiab tsim cov duab los ntawm kev cuam tshuam nrog cov khoom sib txawv. Lub luag haujlwm tseem ceeb ntawm X-ray raj muaj xws li:
X-ray tiam:
Nyob rau hauv lub X-ray raj, ib tug high voltage yog thov ntawm ob electrodes: lub cathode thiab anode. Lub cathode emits lub teeb tsom electron beam, thaum lub anode feem ntau yog ua los ntawm cov hlau hnyav, xws li tungsten, uas yog lub hom phiaj rau X-ray ntau lawm. Thaum lub teeb hluav taws xob los ntawm cathode ntaus lub anode, nws tsim X-rays los ntawm cov txheej txheem hu ua bremsstrahlung.
Focusing Electron Beam:
X-ray raj muaj xws li lub khob tsom iav nyob ib ncig ntawm lub cathode, uas tsim ib qho hluav taws xob teb uas yuav pab kom mloog zoo rau cov emission electrons mus rau hauv ib tug nqaim beam. Qhov kev tsom xam no ua kom ntseeg tau tias cov kab hluav taws xob hluav taws xob ntaus lub anode kom raug, ua kom X-ray ntau lawm efficiency.
Thaum tshav kub kub Dissipation:
Lub cim ntawm X-rays nyob rau hauv lub X-ray tube ua rau cov khoom ntawm tshav kub raws li ib tug byproduct. Txhawm rau tiv thaiv kom tsis txhob muaj cua sov thiab kev puas tsuaj, X-ray raj tau nruab nrog cov txheej txheem txias, xws li tig anode lossis roj immersion, kom dissipate tshav kub thiab tswj kev ua haujlwm zoo.
Kev sib koom ua haujlwm ntawm X-ray Tube hauv X-ray Machine:
X-ray raj koom tes nrog lwm cov khoom hauv lub tshuab X-ray kom muaj kev nyab xeeb thiab ua haujlwm zoo. Kev sib koom tes ua haujlwm suav nrog cov kauj ruam hauv qab no:
X-ray Beam Control:
X-ray tshuab suav nrog collimators, uas yog adjustable diaphragms los yog shutters, los tswj qhov loj thiab cov duab ntawm lub X-ray beam emitted los ntawm X-ray raj. Qhov no ua rau tus neeg teb xov tooj txwv tsis pub X-ray raug rau thaj chaw uas xav tau, txo cov hluav taws xob tsis tsim nyog rau tus neeg mob lossis cov khoom nyob ib puag ncig.
Tus neeg mob Positioning:
Kev tso tus neeg mob kom raug yog qhov tseem ceeb heev kom tau txais cov duab X-ray kom raug. Cov tshuab xoo hluav taws xob muab kev txhawb nqa, xws li lub rooj lossis lub rooj zaum, kom tso tus neeg mob kom raug txheeb ze rau lub raj X-ray. Qhov no ua kom ntseeg tau tias X-rays dhau los ntawm cheeb tsam xav tau thiab ntes cov ntaub ntawv kuaj mob tsim nyog.
Image Receptor Placement:
X-ray tshuab tso cai rau kev tso cov duab receptors, xws li X-ray zaj duab xis lossis digital sensors, nyob rau hauv txoj hauj lwm meej los ntes cov X-rays uas dhau los ntawm tus neeg mob. Cov receptors no nyob rau sab nraud ntawm X-ray raj, ntawm ib qho kev ncua deb, txhawm rau txhim kho cov duab zoo thiab txo qhov cuam tshuam.
Radiation Safety Measures:
Cov tshuab xoo hluav taws xob suav nrog cov hluav taws xob tiv thaiv hluav taws xob, xws li cov khoom siv lead ua, cov phab ntsa hauv cov hlau lead, thiab cov kev tiv thaiv kev tiv thaiv, kom txo qis hluav taws xob cuam tshuam rau cov kws kho mob thiab cov neeg mob. Cov kev ntsuas kev nyab xeeb no yog qhov tseem ceeb hauv kev tswj hwm qhov chaw ua haujlwm nyab xeeb thiab ua raws li cov cai tswj kev nyab xeeb hluav taws xob.
Xaus:
X-ray raj yog ib qho tseem ceeb ntawm cov tshuab X-ray, lub luag hauj lwm rau kev tsim cov X-rays siv rau hauv kev kuaj mob. Nws cov haujlwm, suav nrog X-ray tiam, electron beam tsom, thiab cua sov dissipation, pab tsim cov duab zoo. Los ntawm kev sib koom tes ua haujlwm nrog lwm cov khoom siv, xws li collimators, cov neeg mob qhov chaw, cov duab receptors, thiab kev ntsuas hluav taws xob tiv thaiv hluav taws xob, lub raj X-ray ua kom cov txheej txheem pom tseeb thiab nyab xeeb. Kev nkag siab txog lub luag haujlwm thiab kev ua haujlwm ntawm X-ray raj ua rau peb txaus siab rau cov thev naus laus zis uas cuam tshuam cov tshuab X-ray thiab lawv cov txiaj ntsig zoo rau ntau yam.
