Ib X - hluav taws xob generator feem ntau muaj ib qho X - ray lub cev los tsim X - rays . Ib X - ray raj yog lub raj nqus yooj yim uas muaj cov cathode, uas coj cov kwj hluav taws xob mus rau hauv lub tshuab nqus tsev, thiab anode, uas khaws cov hluav taws xob thiab ua los ntawm tungsten kom tshem tawm cov cua sov uas tsim los ntawm kev sib tsoo.
Ntawm no, yuav ua li cas tshuab hluav taws xob X tsim hluav taws xob x?
Ib x - ray beam yog tsim tawm los ntawm kev hla lub tshuab hluav taws xob hla lub tshuab nqus tsev ntawm cathode (-) thiab anode (+). Qhov zoo them nyiaj anode nyiam qhov txav nrawm, tsis zoo them nqi hluav taws xob.
Qhov thib ob, lub tshuab xoo hluav taws xob ua haujlwm li cas? Yuav Kho Li Cas X - Rays ua haujlwm . Thaum lub X - rays kis los ntawm lub qhov ncauj, tus cov hniav thiab cov pob txha nqus tau ntau dua ray tshaj li cov pos hniav thiab cov nqaij mos, yog li cov hniav pom qhov sib zog ntawm qhov kawg X - ray duab (hu ua duab hluav taws xob). Cov cheeb tsam ntawm hniav lwj thiab kab mob zoo li tsaus nti vim lawv tsis nqus ntau npaum li cas X - ray.
Hais txog qhov no, X Ray tau tsim li cas?
Tom qab ntawd thaum Lub Kaum Ib Hlis 8, xyoo 1895, tus kws qhia paub txog physics German Wilhelm Conrad Roentgen ua ib qho kev pom zoo. Nws tau siv lub raj zoo ib yam li lub teeb roj fluorescent, tshem tawm tag nrho cov huab cua thiab ntim nws nrog cov pa tshwj xeeb. Thaum nws dhau qhov hluav taws xob hluav taws xob siab dhau los ntawm nws, lub raj tso tawm qhov ci ci.
Tus nqi ntawm X ray yog dab tsi?
X - rays yog hom hluav taws xob hluav taws xob. Qhov no txhais tau tias lawv yog cov nthwv dej, tsis yog cov khoom me me. Lawv tsis muaj a nqi , zoo li cov khoom ua. Thaum lub zog hluav taws xob siab hauv lub raj xa tawm sib tsoo nrog cov anode, cov hluav taws xob nkag tau raug tsim tawm uas hu ua X - rays.

Tus kws saib xyuas hluav taws xob hluav taws xob ua dab tsi?
Cov kws saib xyuas hluav taws xob oncology tau qhia tshwj xeeb hauv kev kho hluav taws xob thiab ua haujlwm ze nrog koj tus kws kho hluav taws xob hluav taws xob. Ib feem ntawm lawv lub luag haujlwm yog los tshuaj xyuas koj li cas thiab pab koj daws qhov kev hloov pauv hauv koj txoj kev kho mob. Lawv yuav piav qhia thiab pab koj los tswj cov kev mob tshwm sim
Thaum twg yog siv hluav taws xob hluav taws xob thawj zaug?
Keeb kwm ntawm kev siv hluav taws xob hluav taws xob pib nrog Wilhelm Roentgen xyoo 1895. Wilhelm muaj peev xwm ua thawj xoo hluav taws xob, uas yog nws tus poj niam thiab yeej qhov khoom plig Nobel hauv kev siv tshuaj hauv xyoo 1901 vim nws qhov kev tshawb pom tshiab
Puas yog koj siv hluav taws xob tom qab kev kho hluav taws xob?
Qee cov neeg mob qog noj ntshav uas tau txais kev kho hluav taws xob txhawj xeeb tias lawv lub cev yuav dhau los ua "xov tooj cua" tom qab lawv tau txais kev kho hluav taws xob. "Kev siv hluav taws xob me me tuaj yeem siv tau txhua hnub nyob rau ib lub sijhawm txij li ob peb hnub mus rau ntau lub lis piam
Ntev npaum li cas qhov chaw nyob rau hluav taws xob hluav taws xob?
Tom qab koj ua tiav kev xyaum ua haujlwm ib xyoos, koj yuav tsum ua kom tiav 4 xyoo nyob hauv kev kuaj mob. Thaum lub sijhawm koj nyob, koj yuav tsum tau zaum rau ntau qhov kev xeem ua los ntawm American Boardof Radiology. Qhov no suav nrog kev sau ntawv thiab kev hais lus ntawm rooj sab laj thiab kev tshuaj xyuas lub cev
Puas yog hluav taws xob hluav taws xob tsis yog ionizing?
Tsis-ionizing (lossis tsis-ionising) hluav taws xob yog hais txog txhua hom hluav taws xob hluav taws xob uas tsis muaj lub zog txaus rau quantum (photon zog) rau ionize atoms lossis molecules - uas yog, kom tshem tawm cov hluav taws xob los ntawm lub atom lossis molecule
