DR feem ntau yog tsim los ntawmX-ray raj, X-ray high voltage generator, tiaj vaj huam sib luag detector, mechanical parts thiab imaging system.Tus yuam sij rau X-ray duab yog qhov ntom ntom.Nta: tus nqi qis, yooj yim, hluav taws xob.
X-rays, pom lub teeb, thiab ultraviolet lub teeb yog tag nrho cov hom ntawm electromagnetic spectrum, tab sis nrog txawv wavelengths thiab frequencies.Vim hais tias lub wavelength ntawm X-ray luv luv, luv dua lub wavelength ntawm atoms, thiab lub zog yog heev nkag mus rau hauv, nws muaj peev xwm cuam tshuam nrog atoms, yog li ionizing nws.Cov ions txuas ntxiv hnov mob thiab cuam tshuam nrog DNA ua rau kev hloov pauv, teeb meem hluav taws xob peb txhua tus mob siab txog.
Zaj duab xis yog rhiab rau X-rays, thiab X-rays nthuav tawm cov yeeb yaj kiab, yog li CT tau yug los.Tua ntau cov duab los ntawm ntau lub kaum ntse ntse, thiab tom qab ntawd siv cov algorithm los ua kom lawv ua 3 qhov ntev.Cov pob txha ceev yog siab, yog li nws yog qhov ci heev thaum tua.
Siv qhov sib txawv ntawm cov teeb liab tsim los ntawm kev nqus ntawm X-rays los ntawm tib neeg lub cev rau cov duab, covX-ray zaj duab xis yog sib npaug rau nias tus neeg mus rau hauv lub dav hlau, thiab tom qab ntawd saib qhov sib txawv ntawm qhov nqus nqus ntawm X-rays ntawm lub dav hlau no.
Yog li ntawd, X-raysyog qhov zoo rau cov khoom siv ntom ntom xws li cov pob txha.Tshwj xeeb tshaj yog txawv teb chaws lub cev, vim hais tias txawv teb chaws lub cev feem ntau muaj ib tug kuj siab ceev.Hauv kev tshuaj xyuas cov pob txha, txha nraub qaum, pob qij txha thiab lwm cov kab mob hauv cov organic, qhov chaw, qhov loj me, qib thiab kev sib raug zoo nrog cov ntaub so ntswg ib puag ncig ntawm cov kab mob tau qhia meej meej.
